South Ridge

Crib Goch is the classic alpine-style ridge on Snowdon and one of the most famous mountaineering routes in Britain. It is a narrow, exposed arête with sustained scrambling and significant fall exposure on both sides. The route is usually climbed in dry, settled conditions and is serious in wet, icy, or windy weather. Hands are used throughout much of the ridge, and route-finding is important, especially around the pinnacles and bypasses. It is commonly treated as a Grade 1 scramble in UK terms, but it is the most mountaineering-like of Snowdon's standard routes. The route finishes by joining the main summit ridge before the final ascent to Yr Wyddfa.

Y Lliwedd is a well-known mountaineering ridge on the south side of Snowdon, often climbed as part of the Snowdon Horseshoe. It offers a more serious and less frequented scrambling experience than the main walking routes. The route involves broken rock, ledges, and short steep sections, with route-finding needed in mist. It is exposed in places and can feel much more alpine than the mountain's hiking paths. In winter or poor weather it becomes a much more committing climb. It is a classic objective for scramblers and mountaineers seeking a ridge route on Snowdon.
