A former slate tramway crosses fields from the A470 east of Dolwyddelan and is now a public footpath leading to a bridge over the Afon Lledr. Underneath the bridge is a good sized and reasonably deep pool, with a small 'beach' backed by a grassed area.
Access is via the public footpath and parking is at a a layby on the south side of the road about 100 yards east of the footpath.
