Llyn Gwynant Walk Description

This lovely walk isn’t particularly well-marked, so we recommend downloading the map and turning back to retrace your steps whenever you feel you’ve gone far enough.

The trail begins from the Llyn Gwynant Campsite. Approach the shore and follow the path that wraps around the lake heading to the left. You’ll follow the shores of the lake until you cross Afon Cors-y-Celyn. Here, take the trail that branches off to the left.

Stay left as there is a private trail that intersects with your trail several times. You’ll be mostly following Afon Cors-y-Celyn as you gain modest elevation.

You can follow this trail for several kilometres, but most will stop on the ridge that overlooks Llyn Gwynant, as this is the most rewarding viewpoint. Retrace your steps from here, taking care to stay right off of the private trail.

You’ll gently descend to the lakeshore. Turn right once you reach the main trail at the shore and continue to the campsite.

Insider Hints

  • There is a fairly robust network of walking trails in the area, so extending and customizing your journey is easy
