Know Before You Go
The lake is on private property. Those who still choose to visit do so at their own risk.
Driving from Dolgellau to Fairbourne on the A493, go 1/2 mile past the Fairbourne turn until you see a phone box on the right. Turn onto the road opposite the phone box and park. Then walk up the road until a footpath is signed off to your right, follow this footpath until it turns sharp left over a stile. At this point carry straight on onto a flat plateau area, the tunnel entrance to the lake will be on your left.
