Llanaber Beach is mostly sand and backed by a sea wall which protects the railway. It can be reached from Llanaber village by either of two footpaths from the A496. The first of these leaves the road on the south side of the cemetery, crosses the railway by a footbridge and continues south between the railway and a sea defence wall of boulders. The better option, which is signposted to the station (Llanaber) crosses the railway and leads to a ramp down to the shore, but as the tide comes right up to the sea wall this can only be used for two hours (at most) either side of low tide.
Parking nearby is difficult, so the best option would be either to park at the northernmost car park at Barmouth and walk, or come by train.
