The Avisio is a stream in northern Italy that is 89 km long and springs from the glaciers of the Marmolada. Its waters flow through fairy-tale mountain landscapes and spectacular valleys such as Val di Fassa, Val di Fiemme and Val di Cembra, before merging into the Adige River near Lavis, close to Trento.

In this article, we will take a trip through the waters flowing in one of the most beautiful valleys in Trentino, the Val di Fiemme, focusing mainly on the stretches licensed by the Associazione Pescatori Dilettanti Val di Fiemme.

Obviously, the spotlight will be on the Avisio, but it is only fair to point out that this stretch of the stream is fed by numerous mountain creeks, which flow amidst beautiful coniferous forests, and which in turn are fed by countless alpine lakes literally set like precious stones on mountains of unique beauty. In each of these waters it is possible to fish with a single fishing licence, as they are all managed by the Associazione Pescatori Dilettanti Val di Fiemme (Val di Fiemme Amateur Fishermen's Association).

Among these, I have to briefly mention the Travignolo, the main tributary of the Avisio, and the Lagorai lake, located on the mountain range of the same name. The Travignolo is a beautiful, unspoilt mountain stream, flowing between breathtaking canyons and fascinating waterfalls, and is the perfect place to dry-fly fish for wild, rustic brown trout. Moreover, Lake Lagorai is certainly one of the most beautiful alpine lakes managed by the Associazione Pescatori Dilettanti Val di Fiemme. Situated at 1870 metres above sea level, it is the largest alpine lake in the Lagorai mountain chain inhabited by fantastic arctic char and brook trout, some of them even quite large.

Thanks to this huge variety of fishable waters, Val di Fiemme offers you an all-round fishing experience that will be unforgettable memories.

But back to the Avisio...

If you are a fly-fishing enthusiast, and if you read this blog article you probably are, you cannot help but be breathless in front of the majesty of the fish that populate the waters of the Avisio, such as the marble trout, the undisputed queen of this stream, which shares its habitat with beautiful brown trout and powerful hybrids. It is not impossible to catch some rainbow trout too, although it is extremely rare. Fish such as grayling and brook trout, on the other hand, are not present.

But it is not just the fishing that will fuel your fascination for this valley. You will also be impressed by its gastronomy, which will offer you a unique culinary experience. Dishes such as polenta with melted cheese, stew, dumplings, but also local cheeses and cold cuts such as puzzone di Moena and speck, will leave an indelible impression on your taste buds. The list would still be long, going through typical sweets, wines and local grappas. Let me just mention Fiemme beer and Fiemme coffee, both of which are made entirely locally and which, in my opinion, you simply can’t miss to taste abundantly on site.

In Val di Fiemme you can also go on unique mountain treks and reach beautiful ‘malghe’ (shepherd's huts) where you can taste the best of local products, but you can also enjoy a variety of family-friendly outdoor activities. In short, a whole article would be needed to talk about Val di Fiemme, and I don't want to extend myself too much on that topic. What matters is that fishing is just the tip of the iceberg of what Val di Fiemme has to offer you, and it is certainly the perfect place to combine your passion for fly-fishing with a family holiday.


The Avisio stream, which is managed by the Associazione Pescatori Dilettanti Val di Fiemme (Val di Fiemme Amateur Fishermen's Association), can be divided into two parts: the large Avisio and the small Avisio.


The large Avisio starts from the Stramentizzo reservoir and goes up to the confluence with the Travignolo and the outlet of the Predazzo hydroelectric power station. This stretch has a greater flow rate and size due to the fact that it is fed by many mountain streams, one of which is the Travignolo, and, as already mentioned, by the drainage of the hydroelectric power station, which influences both the flow rate and the activity of the fish.

For this reason, when fishing in this stretch you should pay particular attention to the water levels, which, even if they do not undergo an extreme hydropeaking, could complicate your return to shore when wading in the middle of the stream.

Certainly, fishing in the large Avisio is more likely to catch some nice marmorata, although there is no shortage of them in the small Avisio either.

Morphologically, this torrential stretch is very varied, and travelling along it you can encounter rapid currents, long runners, deep pools and large weirs. This entails quite technical fishing, with constant changes of set-up and nymph weights. Laziness, as in most cases, could be the number one cause of unprofitable fishing.

The large Avisio can be successfully fished along its entire length, without the danger of finding yourself in uninteresting areas. The fish are well distributed over the entire stretch, and the catch of your dreams could hide wherever you lay your eyes.

The small Avisio starts above the outlet of the Predazzo hydroelectric power station and also cuts off the Avisio's main tributary, the Travignolo. This stretch of the stream has a much lower flow rate and size and, as is to be expected, is not affected by hydropeaking, which ensures a constant flow throughout the year.

The interesting characteristic of the small Avisio is that it is generally fishable even when the large Avisio is not, perhaps because of heavy rainfall. In fact, this stretch has the characteristic of getting less dirty than its bigger brother, and in any case, its water cleans up and becomes fishable again in a much shorter time. If you have arrived in Val di Fiemme and found yourself in front of the large Avisio, which is not very fishable, I therefore suggest having a look at the small Avisio, it could make your day.

The small Avisio is a well-structured stream and, despite its lower flow rate, here too you can find big pools where you can catch some nice fish. The trout are well distributed along the entire stretch, and you have a good chance of catching them almost anywhere.

In this chapter I have subdivided the Avisio stream taken over by the Associazione Pescatori Dilettanti Val di Fiemme subjectively into different beats. For each beat I have marked the best free parking areas where you can leave your car, to allow you to fish as conveniently as possible. In addition to the car parks I have marked, there are many other places where local fishermen and some guest fishermen leave their cars. In these places, however, parking is tolerated, but not exactly in accordance with the road traffic code, and so I have preferred to omit them.

In addition to the free parking areas, I have also marked other points of interest, such as fishing lodges, underpasses and important junctions that may be of some interest for fishing purposes. Each point is correlated with a GPS link that allows you to easily reach it with a click through Google Maps.

For each beat I am going to name the best bank to approach the stream in my opinion. A suggestion that can be especially valid for those who come fishing in the Avisio for the first time. Obviously, you do not have to strictly follow these suggestions, especially if you have some experience of the place, but in general if you don't want to seek adventure and prefer to fish in a relaxed manner, the indications on accessibility stated below are an excellent starting point.

I did not want to mark the various protection zones (ZT), as they change over time. I therefore preferred to give reference points that are unlikely to be changed and will therefore always be valid and accessible. I have placed the protection zones (ZT) within the chapter ‘regulations’, which I will try to keep updated if there are any changes.

3.1.1. BEAT 1 (1.86 km)

The waters under concession to the Associazione Pescatori Dilettanti Val di Fiemme begin at point A, well delimited both by an old iron bridge in disuse and by an actual bridge, where the road from Cavalese to Masi passes.

In order to fish this stretch, it is possible to park in the industrial area (point 1), cross the state road thanks to the underpass (point 2) and descend towards the beginning of the beat thanks to a very convenient and accessible footpath which runs along the entire right orographic bank, and then come back up to your vehicle while fishing.

For almost the entirety of beat 1, the more accessible stream site is the right orographic bank, as well as being the one that makes fishing easier. The left orographic bank is decidedly more difficult to reach, but also more difficult on a practical level to fish itself due to the fact that in many places it is quite overgrown, and I personally do not recommend it, especially for those who are not familiar with the area.

In this stretch, with the exception of a few points, wading is particularly difficult, if not impossible, even with medium/low levels.

If you are interested in fishing in the initial part of the stretch, you might consider leaving your vehicle in the nearby village of Masi di Cavalese. There are also other parking areas closer by, where parking is tolerated but not officially permitted, and as mentioned above, I preferred to omit them.

Morphologically, this stretch of river has a beautiful deep runner at the beginning of the beat, just below the bridge, and then immediately becomes more structured with many boulders scattered throughout the riverbed, from which a variety of different currents and beautiful as well as deep pools are formed. Especially in the final stretch there are some very interesting spots at the weirs.

3.1.2. BEAT 2 (2.44 km)

Beat 2 is really very interesting, personally I consider it one of my favourites. Access to the stream is very easy along almost its entire length, becoming a little more complicated in the final part.

There is also a gravel road along the entire length of this beat, which runs along the entire orographic right bank of the stream and thus allows easy movement from one spot to the next or simply back to the car. This path is not present in the last 400 metres leading to the wooden bridge (point C).

In my opinion, spot 4 is definitely the best place to park your car. From here, I recommend crossing the bridge on foot to reach the right orographic bank of the Avisio, which is certainly the most convenient for fishing in this stretch. Once there, you can decide whether to fish upstream or walk down first and then go back up fishing.

Morphologically, this stretch of stream is very varied and has weirs, large pools and deep-water runners within it. To fish effectively, you will need to be very dynamic in changing the setting of your equipment.

Along beat 2, about 800 metres from the banks of the Avisio, you will find Maso Piasina (point 5), a farmhouse nestled in nature, where you find yourself in an atmosphere of absolute peace. In addition to being one of the most beautiful holiday farms in Val di Fiemme, Andrea, the owner, is also a passionate fly fisherman and will be able to give you valuable advice on how and where to go fishing during your stay. In addition, at Maso Piasina you will find dedicated services for anglers, such as: breakfast at dawn, a space dedicated to dry your waders, and, of course, the possibility of getting the necessary fishing licences. Needless to say, this is the perfect place if you want to have a fishing holiday with your family. For further information, please visit Agritur Piasina website.

3.1.3. BEAT 3 (2.20 km)

The first part of beat 3 is certainly the most beautiful and suggestive of the entire Avisio in terms of landscape and morphological attractiveness. About 500 metres long and straddling between beat 2 and beat 3, this area of the stream has remained unchanged over time and is a perfect postcard that tells the story of how the Avisio was from its origins. In this stretch of water, you will find large boulders forming deep pools and runner that are very interesting for fly fishing, and the old wooden bridge, located about halfway along this stretch, adds to the evocative atmosphere of one of the most fascinating places you will find in this stream. It is not easy to fish and walk along, especially if the levels are medium to high, but it is definitely a place where you have to do a couple of casts when you come to fish in Val di Fiemme. The more accessible bank is definitely the left orographic one, which can also be fished with medium/high levels if you have a bit of experience, while the right orographic bank is definitely the least beaten and can only be fished with low levels.

Definitely one of the most beautiful and fascinating spots on the entire Avisio stream.

For the rest, beat 3 is very well structured, broken up by a very important weir located near point 7, beyond which the stream forms very beautiful and deep-water runners, especially in the central part.

Also, near points 8 and 9, the stream creates some really interesting spots to fish and is an excellent starting point for tackling this beat. Once you have parked here, you can take advantage of the cycle path that runs alongside the stream on its right orographic bank, which gives you very easy access to the river along almost its entire length, except for the final stretch, which has a fairly high and steep riprap riverbank protection wall to descend. Accessing from the orographically left bank is definitely more complicated, although it is possible in some places, but I recommend staying on the orographically right bank, especially for those who have no experience of the area.

3.1.4. BEAT 4 (2.27 km)

The initial part of beat 4, which basically runs from point D to a fairly large weir (250 metres as the crow flies), is very interesting and I recommend fishing it from the right orographic bank. To access this beat, you will have to descend a fairly high riprap riverbank protection wall, the same as you will have to ascend once you reach the bridleway, so be very careful. If you want to fish in the remaining parts of beat 4, I recommend that you travel by car at least as far as point 13.

However, my advice for tackling beat 4 is to park at point 14 and eventually walk down a convenient footpath that runs along the right orographic bank of the stream and then go back up fishing.

In general, beat 4 is very varied in terms of morphology, with deep runners, large pools, weirs and changing currents, which make fishing very technical. The more accessible bank is certainly the right orographic bank and free parking possibilities are well distributed along the entire stretch. The left orographic bank is also, on the whole, very accessible, but as it is only bordered by a cycle path, it is a little more difficult to reach, because you have to walk a little. Wading is quite complex, if not impossible along the entire stretch, although it is possible in some places provided the levels allow it. However, I do not recommend wading the stream, because at the end of the fishing trip you could find yourself in a spot where it is impossible to turn back, being forced to reach the first bridge on foot and then having to walk a really long way back to the car.

3.1.5. BEAT 5 (815 m)

Beat 5 is very structured, with well-distributed, smaller boulders that create interesting fishing spots. In addition to this, you will also find numerous weirs that are not particularly large, but which form more or less deep pools where you can cast your flies. You will be able to enter the stream very easily and fish wherever you like, unless there is a large flow of water. The banks are quite accessible, thanks to the convenient footpaths that run along both sides of the stream.

The end of beat 5 (point F) is a very important key point of the Avisio stream, because this is where the confluence with the Travignolo is located (point 18) and the outlet of the hydroelectric power station connected to the Pezzè di Moena dam (point 17).

With the same fishing licence, it is also possible to fish in the Travignolo, undoubtedly the most beautiful tributary of the Avisio, a special place where dry fly fishing takes over, but that is another story.

From here on, the stream's flow rate decreases considerably for obvious reasons, remaining constant throughout the year, being influenced neither by the Travignolo nor by the discharge of the hydroelectric power station, but we will go into this in more detail in the description of beat 6.

3.1.6. BEAT 6 (3.88 km)

Beat 6 is what is known as the ‘Small Avisio’, because it is located above both the outlet of the hydroelectric power station and the confluence with the Travignolo, the main tributary of the Avisio. The advantage of this stretch is that it is less easily fouled and, in any case, cleans up quickly, becoming fishable again in a short time even after a storm. Its flow is mainly determined by the residual runoff released by the Pezzè dam, but despite being considerably less than the lower part of the Avisio, this stretch can hold some very interesting surprises. Here, too, there is no lack of deep pools, long runners and a well-distributed structure over the entire stretch.

In beat 6, accessibility to the stream is very good along almost its entire length and given the low water flow rate and the smaller size of the stream, it is possible to wade through it without problems and in safety at many points, although great care must always be taken!

You can fish the whole Avisio with dry flies, classic nymphs or streamers, but let me point out some personal observations regarding the choice of the fly type. In principle, this is a stream that lends itself mainly to nymph and streamer fishing; the window of the season in which dry fly-fishing brings a reasonable number of catches during the day is quite small. Moreover, the best times are around dusk and last an hour or so. It goes without saying, therefore, that having to drive many kilometres, with all the attendant expenses, to come to the Avisio just for dry fly fishing may not be a good investment and I personally would advise against it, but of course you are free to do as you wish.

If you are a fan of dry fly fishing, I highly recommend the Travignolo, the tributary of the Avisio that we spoke about earlier. There you can make excellent catches and have fun with the dry fly technique all day long. In this stream the fish are not particularly picky, and you will be able to get excellent results with a lot of different fly patterns, but perhaps we will go into this in more detail in another article.

If you absolutely want to fish in the Avisio with dry flies, I recommend doing so in the small Avisio, and then perhaps moving to the large Avisio towards the evening in the spots that are most suitable for this fishing technique. The best area in my opinion is from the Ski Center Latemar (point 20) upwards.

You can find the most attractive fly patterns in our online fly-fishing shop and be sure to take a look at our Made in Italy dry flies.

Nymph fishing, especially at Euronymph, is the one that will surely give you the greatest satisfaction along with streamer fishing.

Marble trout from the Avisio

This is not to say that the Avisio is an easy water to tackle; on the contrary, if you don't know how to fish it in the right way it can of course happen that you won’t see any fish the whole day. That said, it doesn’t require special fly patterns to be successful. A common fly as the classic white/black nymph, perhaps with a red hotspot, is certainly a pattern that can give you a lot of satisfaction throughout the season, if you want you can take a look at our Made in Italy competition nymphs.

Nymphs from our Made in Italy series

At the right time of year there is also a strong presence of trichoptera and the peeping caddis nymphs could be an excellent choice. Red- or orange-beat headed nymphs are also perfect, to be used preferably at times of high and cloudy water, where even the classic squirmy worm can have its say.

You can also find these fly patterns in our online fly-fishing shop

Often, because of the sustained current and deep pools, you may need some heavier nymph patterns such as the Jig Bomber nymphs.

Indispensable fly patterns to get straight to the bottom of the big pools


As there is a strong presence of large marmoratas, streamer fishing is definitely a good choice, especially with medium/high levels and cloudy water. Going deep into big pools or deep runners with the right streamer could really give you the fish of a lifetime; so, if that is your goal, try to have the right equipment for fish which can non uncommonly weigh up to 5 kg or even more.

Marble trout from the Avisio

Certainly, using weighted streamers allows you to fish immediately in the desired spot and could definitely make a difference.

Again, you can find a large selection of streamers suitable for big trout fishing in our Made in Italy streamer range.

For dry fly fishing in the Avisio you you are surely fine with a universal fly rod, i.e. the classic 9' line class #4/5, especially if you fish in the large Avisio. Whereas if you decide to fish in the small Avisio, a setting for the ICS (Italian Casting Style) casting technique, with a 7'6’ #3 rod, could also be fine. Being a particularly structured river, the Avisio is very technical for dry fly fishing and some casting experience is certainly required to achieve satisfactory results.


For classic nymph fishing, here too you can use universal equipment, i.e. the classic 9' #4/5 fly rod, in both the large and small Avisio.

If, on the other hand, you want to fish Euronymph style, the classic rod sizes used for this technique, from 10‘ to 11’, are fine. As is to be expected, a longer length will be preferred in the large Avisio whereas you’ll doing just fine with a somewhat shorter fly rod in the small Avisio. In the latter, a 9' rod can also be used without any problems. Given the size of the fish present and the strength of the current, it is a good idea not to go below a size #3 class.


In most cases, a 9' #5 is very good for successful streamer fishing, but as you will have realised, there are few but real possibilities of hooking truly remarkable fish when fishing with this technique. Therefore, it is not totally unreasonable to increase the line class of your fly rod slightly, especially if you are specifically going in search of trophy sized marmoratas.

Marble trout from the Avisio


You can get your fishing licence for example in different bars of the valley, such as the historic Bar Croce in Predazzo.

However, I prefer not to make a complete list of bars where you can make a licence, because they change over time, and you may end up with incorrect information.

An always valid point where you can make the licence is certainly the tourist office or the Maso Piasina farmhouse, although I personally recommend you do everything online through the Trentino Fishing web portal, which is much more practical and faster.



The fishing season in Avisio starts on the first Sunday in March and officially ends on 30 September.

For a few years now, a provincial derogation has been obtained that allows fishing in the Avisio also in October. During this period, it will only be possible to fish with the fly, both nymph and dry, and it will not be possible to keep any fish. In addition, it is compulsory to use wading nets with rubber nets and all silicone-based lures, including the squirmy worms, are prohibited. The stretch of the Avisio in which it is possible to fish during this period is practically the same, except that the downstream limit is moved upstream about one kilometre to the confluence with the Rio Lagorai.

It is possible to fish the entire length of the Avisio without any problems, in fact there is no stretch where fishing is banned. However, there are three stretches classified as ‘marmorata protection zones’ where fishing is still possible, but with some differences in the regulations, which we will see below.

WARNING: there are many fishing bans in Alpine creeks and lakes, and I suggest you do all the necessary checks before you start fishing. For further information, consult the website of the Associazione Pescatori Dilettanti Val di Fiemme.

As a general rule, in Avisio it is possible to fish with a maximum of two barbless hooks, trebles are generally forbidden. Moreover, it is possible to keep a maximum of five fish in total, of which only one hybrid. THERE IS A STRICT RULE TO ALWAYS RELEASE MARBLE TROUT! The minimum size for hybrid marmorata is 40 centimetres, while for brown and rainbow is 22 centimetres.

As far as protection zones (ZT) are concerned, it is mandatory to release not only the marmoratas, but also its hybrids. However, it is permitted to retain up to a maximum of five fish also when fishing these protection zones, either brown or rainbow trout, that reach the minimum size of 22 centimetres. To fish in these stretches, the ZT box on the licence must be checked before fishing begins. By checking the ZT box you can still fish outside the ZT zones, but you must comply with the regulations imposed for this type of water on the entire stretch of the Avisio.

If you practice catch and release, and I hope you do, I recommend that you always check the ZT box. This way you do not have to log your catches even if you release them, allowing you to fish the whole day even if you catch more than five fish. Conversely, you would be obliged to log all catched trout that reach the minimum size in your booklet, forcing you to stop fishing once you reach five catches because a recorded catch of a fish that has reached the minimum size equals a kept fish, even if you release it.


I may be biased, because this is where I started fishing, but I personally believe that the Avisio is an extraordinary stream. Not only for the fish that populate it or for the surrounding environment, but also and above all for the strength that this stream has to resist natural and man-made adversities.

The flushing of the upstream reservoir that is done every three years leaves permanent marks on the fish fauna every time, especially on the youngest trout, which can hardly withstand a whole month of water mixed up with mud flowing down from the Pezzè dam.

Storm Vaia then dug an indelible furrow, literally changing the morphology of the stream, with a devastating impact on all the splendid trout that populate it. I still remember the first few times I fished post-Vaia, and it was like fishing in a different water. It was literally unrecognisable; I am not exaggerating.

Despite all this, the Avisio is still there, and it holds its head high against every hard blow it receives from both man and nature. Nevertheless, I hope that all those who want to fish in these waters have the utmost respect for it, the same respect that one should have for all the nature that surrounds us.
