Start with Wet-fly teams (12-14) on a slow, natural presentation — check locally for the preferred method. Rainbows respond to more active retrieves — try short strips between pauses. If that does not produce, switch depth or speed before changing the pattern entirely.
If surface work dries up, try a diawl bach or hare's ear on the point and skate a sedge pattern on the bob at last light.
Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.
Good ripple suits both bank and boat. Bank: work inflows, dam walls, and points. Boat: broadside drift covering wind lanes.

A good match for Lac Saint-Michel (Brennilis) — most conditions are close to what it fishes best in.
At 450 hectares in the heart of the Monts d'Arrée, Saint-Michel is a Grand Lac Intérieur — a big, open reservoir of stocked rainbow trout fished alongside resident pike and perch. This is loch-style water: you fish the wind, the contours and the inflows rather than a pocket of stream. It carries its own lake regulations, separate from the spate rivers all around it, so read the Finistère rules before you launch.
