Four Valleys Path - Nantlle, Gwyrfai, Padarn and Ogwen Valley Walk

19 miles (30 km)

Explore the four former slate mining valleys of Nantlle, Gwyrfai, Padarn and Ogwen on this beautiful walk through Gwynedd. The walk runs from Penygroes to Bethesda passing along the edge of the Snowdonia National Park along the way. Highlights on the walk include the 13th century, Dolbadarn Castle which features one of the finest surviving examples of a Welsh round tower. You will also pass between Llyn Peris and Llyn Padarn in Snowdonia.
These glacially formed lakes are overlooked by Elidir Fawr mountain, with the busy village of Llanberis located on the southern shore of Llyn Padarn.
The walk is waymarked with a green and white disc.
The area's quarrying history can be further explored on the Snowdonia Slate Trail which can be picked up in Bethesda.

Green Lanes. North of Maen-llwyd-uchaf, the steepening Llanberis-Waunfawr road has turned into a green lane not accessible to general traffic. The other green lane, the one linking the two tarred roads upwards from Llanberis, sweeping past the back of Maen-llwyd-isaf (in the trees) contours the hillside below Yr Aelgerth.
