Fishing Tretjärnarna
perch, pike and trout sit at the top of the food chain in Tretjärnarna, carried by roach and ruffe. The clearer water makes the fish wary — and rewards a careful presentation.
The fishing here follows the water's own rhythm: dawn and dusk have their windows, fronts close and open them, and the season moves the fish. No two sessions at Tretjärnarna are alike.
