Character of the water
Frösjön lies in central Sweden — a acidified forest lake. Acidification has thinned life down to the hardiest few.
The surroundings
The lake lies half-remote, a fair way from the nearest road, tucked into woodland.
Shallow throughout (max 3 m), with reeds and vegetation over large areas — water that warms fast in spring.

In the clear water pike picks its moments — wary, but relentless once committed.
Fishing Frösjön
Frösjön holds 2 species, with perch and pike at the top of the chain. The modest depth keeps most of the fishing within reach of the bank.
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 Frösjön are alike.
General rules of thumb for this kind of water
