Snowdon (Yr Wyddfa), Eryri – Mountain Routes in Snowdonia

Summit paths, ridgelines, and glacial valleys in the heart of Eryri

Snowdon, known in Welsh as Yr Wyddfa, rises to 1,085 metres as the highest mountain in Wales within Eryri National Park. A network of established paths ascends from Llanberis, Pen-y-Pass, Rhyd Ddu, and Nant Gwynant, linking valley settlements with the central summit ridge.

The mountain stands at the centre of a dramatic glacial landscape of cwms, lakes, and steep-sided valleys. Underfoot, terrain varies significantly depending on route. The Llanberis Path follows a long, steady ascent on stone and gravel, while the Pyg Track and Miners’ Track climb more directly over rocky ground above Llyn Llydaw. The Watkin Path rises steeply from Nant Gwynant, and the Rhyd Ddu Path approaches along a narrower ridge. Gradients increase near the summit, with exposed sections and loose stone common on upper slopes.

Snowdon is heavily visited in fair weather, especially during summer months. Despite this, conditions can change rapidly, with cloud, wind, and rain affecting visibility and footing. The summit area is rocky and often busy, marked by a trig point and seasonal visitor facilities.

Routes descend back toward Llanberis or Pen-y-Pass, while longer mountain traverses link surrounding peaks such as Crib Goch and the Snowdon Horseshoe. The terrain is mountainous rather than rolling, with sustained ascent and uneven surfaces across most approaches.
