Nant Gwynant autumn walk


Step out this autumn and explore the lower slopes of Snowdon and Nant Gwynant valley, where you'll discover a landscape steeped in history and rich colours.

Walk through wooded glades in a tranquil valley

Pass under the orange canopy of oak woodlands, keeping an eye out for interesting fungi along the way. Ascend the famous Watkin Path out into the open fields of fading green dotted with the rust of bracken die-back at Cwm Llan. Pass the intriguing ruins of Cwm Llan House and head towards Craflwyn, watching out for feral goats as they start to descend the hills and seek shelter in the wooded glades.
