About this water

The Sipoonjoenpuro is a small stream in Sipoo, east of Helsinki — intimate water with wild brown trout and grayling in clear, shallow runs. Urban-fringe fishing, which means accessible rather than crowded, close without being compromised. The trout are small and genuinely wild and feed properly on insects when the hatches are on. The kind of water that asks nothing heroic of the angler — just a light tippet, the willingness to move slowly, and the habit of watching the water for a few minutes before making the first cast.
