Gwydir Forest and Swallow Falls
Betws-y-Coed is bordered by Gwydir Forest, which has several well-marked walking trails. The forest also contains a half dozen or so mines, the last of which was abandoned in the 1940s. On the western approach to the village, you'll find Swallow Falls, where the River Llugwy tumbles down through a wooded chasm. The trail to Swallow Falls (Rhaeadr Ewynnol) is a strenuous circular walk, which takes at least a couple of hours.
