The Dysynni Gorge
Leave Abergynolwyn Station and, after a short stretch of road, you are soon walking along a steep gorge defined by the Afon Dysynni, which squeezes through this narrow gap before reaching Dyffryn Dysynni, where it turns south-west and heads for the sea. A very quiet lane is then joined at Pont Ystumanner and this is followed for a short way to Llan llwyda, with the craggy hulk of Bird Rock directly ahead.
