The Snowdon Massif

Yr Wyddfa · Central Snowdonia

Yr Wyddfa (Snowdon) and its satellite ridges form the most famous mountain landscape in Wales. At its heart, the Snowdon Horseshoe links Crib Goch’s knife-edge arete, the summit of Yr Wyddfa itself, and the long ridge of Y Lliwedd around a spectacular glacial cwm. To the west, a quieter chain of lower summits — Moel Eilio, Foel Gron, Moel Cynghorion and Yr Aran — offers gentler walking with some of the best views of the high peaks.

Safety & weather

  • Snowdon is the busiest mountain in Wales; the main paths can be extremely crowded in summer.
  • Weather changes fast at altitude even when Llanberis below is clear and sunny.
