Traeth Llydan is a wide beach of coarse sand backed by dunes situated just east of the village of Rhosneigr. The A4080 leading into the village from the east has a wide gravelled verge along its northern side where vehicles may be parked. From here a few footpaths lead across the dunes to the beach. Dogs are allowed at all times.The village of Rhosneigr has a few small shops and cafes and a railway station. The station is just over a mile from the beach and can be reached via public footpaths alongside Llyn Maelog.
