Slovenia is known for beautiful and large graylings! On average anglers catch specimens between 30 and 40 cm, every year several trophy specimens are being caught, even up to 50 cm.
Grayling is very interesting fish to fish for. The only method that is allowed is fly fishing. One can successfully apply bot dry fly fishing and nymphing as well. Probably the best fisheries for fly fishing for grayling are Sava, Ljubljanica, Vipava and Poljanska Sora. Want to come and see for yourself? Check the links. You do not need a fishing guide!
