Tryfan

Tryfan's North Ridge climbs from the Ogwen Valley straight to the summit, and it is the best Grade 1 here for building rhythm on sustained rock rather than one or two awkward steps. Expect some route finding: higher up a pinnacle can be avoided by trending left, and beyond it you drop into a notch with gullies falling away on both sides. Much of the rock is heavily polished, so care counts most on the upper pinnacles. The twin summit blocks, Adam and Eve, invite a jump between them that is entirely optional. Descend to the col and stone wall, then back past Llyn Idwal; strong parties continue up Bristly Ridge instead.
