Whether running, hiking or just gently wandering, this Llyn Crafnant Loop is perfect for lowering the heart rate with some easy trails and beautiful scenery.

The short section of forest in roughly the middle of the trail route is particularly spell binding, with moss covered trees, streams and small waterfalls aplenty.

Early morning visits here can be wonderful when we catch the lake on a still day – the reflections are mesmerising.

Midday sunlight filters through the forest section of this walking/trail running route really well, again well worth timing a visit to enjoy this at it’s best.

1. Llyn Crafnant has a great public car park (with toilets) a short distance from the north tip of the lake. From the car park entrance we cross the road and initially walk up a dirt track to the north (away from the lake). This soon turns back on itself and the wide forest track continues for about a mile and a half.


2. After the track descends through a few neat left and right bends, a narrow footpath turns up the right into the woodland. From here all the way down to the side of Llyn Crafnant is some truly special forest, with moss hanging everywhere, carpeting every trunk and branch with it’s lush greens. Small streams run through the trees and there are a number of incredibly beautiful miniture waterfalls.


3. On reaching the Crafnant road and turning left (south west direction), the rest of the Llyn Crafnant Loop is via a very well maintained track that follows the lakeside all the way back to the start. There’s a great little vantage point with a wooden bench not far from the end of the lake which we love for a final coffee break overlooking the water to the forests on the other side that we started off in.
