ABOUT
My name is Lesly Janssen, the locals call me "Lesko".
I am a member and a fly fishing guide for the fly fishing club of Tolmin (RD Tolmin).
​
I am 39, come from the Netherlands, and have been fly fishing and fly tying for over 28 years.
More than half of that time has been spent exploring and learning the rivers of the Soca Valley in Northwest Slovenia.
I have also sought out and fished many rivers in Austria, Croatia, Bosnia, Italy, Germany, Belgium, France, the Netherlands and Colorado, in the United States. additionally, I fish Tenkara, tie flies, shoot and edit photos, and film.

My story...

From the first moment I found the rivers of Northwest Slovenia I fell in deep love with the entire area surrounding the village of Tolmin. It was the impressive nature, the people, the pristine and wild rivers,
the challenging sight fishing and the unique arsenal of fish
species that caught me!
Since my first visit, I haven't left as my intrigue for the land has
kept me exploring. Now I've seen it all and know it better than
my pocket. I just love the sight fishing more than anybody
else I know.
A few years later into my Slovenian discoveries, I started with
the guiding service HookedonSlovenia.com to guide for the fishing
club of Tolmin. I later joined the Soca fly shop with my guiding services until early 2016, when I began my own journey again as SLO-FLY.COM
What I do...
I specialize in sight fishing with dry flies and nymphs and have mastered the skill of finding fish in these remote rivers and canyon stretches including Soca, Tolminka, Ucja, Trebuscica, etc. My favorite method is upstream fishing and catching wild Marble trout in the first cast.
My goal is to make your trip easier and more successful by sharing my knowledge about the area, rivers, and fishing spots.
I will teach you numerous fishing tricks like where to find and on how to have success with the Marble trout and other species on lighter gear with dry flies, nymphs, and small streamers.
To protect our beautiful fish I practice Catch & Release fishing only!
