Day one

Conwy Castle to Nant Gwynant

49km (30.5 miles) | 3800m (12,467ft)

Northern Snowdonia has the rockiest mountains! The Carneddau, Glyderau, and Yr Wyddfa (Snowdon) massif await.

Starting with a gentle climb from the beautiful coastal Conwy Castle, the route gradually becomes rockier with unrelenting ascent and descent, culminating in the airy ridge scramble across Crib Goch and the traverse of the full Yr Wyddfa horseshoe, passing by some astounded tourists.
