Fishing Grimsjön
perch, pike and trout sit at the top of the food chain in Grimsjön, carried by roach. The clearer water makes the fish wary — and rewards a careful presentation.
Every session at Grimsjön is fished in whatever conditions hold right then — the same pressure, wind and light as over the real water. What bites today isn't what bit the day before, and those who return learn the water for real.
