Best Walks in Snowdonia

Eryri — Snowdonia — is the most concentrated block of real mountain terrain in England and Wales. Sharp ridges, deep cwms, volcanic rock, and big views that stretch out to the Irish Sea. It’s a range shaped by fire and ice, and you feel that the moment you step off the valley floor.

The mountains here aren’t soft. Yr Wyddfa rises from a ring of glacial basins. Crib Goch is a true arête — narrow, exposed, and carved by cirque glaciers. The Horseshoe wraps around three hanging valleys. More than a hundred lakes sit in hollows left behind by the last Ice Age. It’s compact, serious terrain.

These routes are chosen because they earn their reputation — not because a brochure says they’re “classic.” They’re the lines with exposure, commitment, and terrain that demands attention. Each one comes with grades and stats so you know exactly what you’re stepping into. Start with the line that matches your experience.
