Fly Fishing Slovenia
Where to go Fly Fishing in Slovenia
Slovenia rests along the southern end of the European Alps. These high peaks separate the two major drainages of the country, the Danube River drainages, and the smaller drainages that feed into the Adriatic sea. The country is home to several species of salmonids including the Huchen (Danube Salmon), grayling, brown trout, and the coveted Marble Trout which are unique to the country in tandem with the neighboring Italian Dolomites. Rainbow Trout have also been introduced to a handful of river systems across Slovenia but do not draw as much attention from visiting anglers as the Marble Trout and Huchen which can grower to larger sizes and ascend the role of the apex predators in the rivers they inhabit.
Fishing the Soca River in Slovenia
Among anglers, Slovenia is best known for the Soča River. The crystal clear turquoise water and
the bright limestone make it one of the most beautiful rivers of the world. The source lies in the
heart of the Triglav National Park which is one of the oldest protected zones in all of Europe. The Triglav
National Park is part of the Julian Alps and marks the southeast end of the range. The Soča river is relatively
short, only about 86 miles long, but possesses more then a dozen modestly sized tributaries that comprise well over 200 miles.
The river attracts anglers from all over the world to catch the Marble Trout that call the river system home. It is one of the most unique relatives of the brown trout which are clearly identified by the vibrant marmorations along it back and side flanks. The marble trout can grow to be some of the largest members of the salmonid family with individuals capable of reaching 48 inches in length and weighing over 50 pounds. We take a deep dive into the fly fishing opportunities on the Soca and its tributaries in this article on Fly Fishing the Soca River.
Fishing the Sava River in Slovenia
While the western drainages of Slovenia tribute in the Adriatic Sea and possess the Marble trout that attract many anglers to the country, the central and northern rivers of Slovenia drain to the Danube River system, and more specifically the Sava River. In these waters lives "The King“. Hucho Hucho, sometimes called the Danubian Salmon is part of the Taimen
family which grow much larger than any trout. Slovenia has a strong population of these apex predators which have become a huge trend for ambitious anglers to target. They are known to be fish of 1,000 casts, or maybe 10.000! They feed sparing and they can dormantly lounge for many days. Good conditions are crucial to have a small chance of shaking hands with one.
Good conditions are a change in the weather to rain or snow, which invite slightly stained or rising water. These can be the most challenging conditions to physically fish but are ideal for the huchen to hunt. Clear, low water and sunshine will almost certainly lead to frustration. Frozen guides and blocked reels make fishing impossible at times but are just another obstacle separating anglers from the glory of landing these massive predators.
Several tributaries in the Sava River system spread all over the country, the largest of which hold the bigger taimen. On some smaller tributaries anglers can find better chances even when the conditions aren’t perfect. For trophy hunters it can be a sheer game of luck when it comes to timing, location, and presentation of your fly.
Some anglers can fish for Hucho for weeks without a bite while others may catch a trophy fish on their first cast if the stars align.
Fishing the Sava Dolinka and Sava Bohinjka
The Sava Dolinka and Sava Bohinjka are the two most popular tributaries of the Sava targeted by anglers looking to land a trophy sized huchen. These waters are a bit less daunting than the much larger Sava. Even smaller tributaries such as the Savinja, hold larger populations of Huchen but are typically much smaller in size. These smaller streams are more suitable for anglers using single handed rods while two handed setups are more common on the larger waters. Medium sized streamer to the largest streamers anglers can tie are all used to target the huchen. These predators can be downright gluttonous when looking for a meal, opting for ANYTHING they can fit inside their mouths.
9 to 12 weight rods are typical for anglers targeting the huchen. Their unique fishing season differs in start time based on conditions and management, ranging between the 1st of October and 1st of November. It will lasts until 15th of March. These regulations change from country to country across the Danube drainges in the Southern Alps and Eastern Balkans.
Fishing the Kupa River

On the Slovenian border with Croatia lies the Kupa River. This small to mid sized spring creek is a dry fly anglers dream. The river is home to Huchen, Brown trout, and European Grayling. These three salmonids occupy the various niches throughout the river with the grayling and brown trout primarily focusing on the insect life of the river and the huchen targeting any fish that swims within the banks of the river. Late Spring through early summer sees the best hatches along the river. Mid September and October see another flurry of bug activity that attracts anglers. Huchen season again spans the colder months with October, through February being the optimal times for anglers to find these predators. Single, barbless hooks are the only permitted on the river.
Mongolian Grayling
Mongolia has the highest diversity of grayling species in the world next to Russia. Four Grayling species including the Arctic Grayling, Siberian Grayling, Amur Grayling, and the Mongolian Grayling, which is the most unique of all can be found throughout the country. The Mongolian Grayling is only found in 3 lakes and their conjoining rivers that are located in the far western edge of the country near the Kazakh border. These borderline desert lakes provide an abundance of food which allows the Mongolian Grayling to grow to tremendous proportions. They are likely the largest grayling species in the world, which prefer a piscivorous diet unique among the Grayling family.
