Walking and mountain bike trails plus more

Gwydir Forest Park lies at the heart of the Snowdonia National Park near Betws-y-Coed. It takes its name from the ancient Gwydir Estate, established by the John Wynn family of Gwydir Castle, which owned the land. Visitors have been enjoying the woodland and rivers in the area since Victorian times. Most of the lakes in the park were created to serve the lead and zinc mines which dominated the landscape between 1850 and 1919. What was once a derelict industrial landscape is now a wonderful expanse of woodland, pastures and lakes. Waymarked walking trails make exploring the park easy and there’s a mountain bike trail too.

The park encompasses 72 square kilometres. It can be accessed from multiple locations with parking:


Llyn Crafnant
Swallow Falls
