Shell Island has the largest camp site in the UK (tel: 01341 241453) with some 300 acres of camping space for tents only. It is reached across a causeway from Llanbedr which floods on some high tides cutting off access by vehicle, but access on foot along the beach from the south is always possible. The cut-off times are shown on a board at the start of the causeway. Day visitors are allowed and there are plenty of places to park, with panoramic views towards Harlech, Snowdonia and the Lleyn peninsula. The beach varies from rocky to sandy, with some impressive sand dunes to the south. This is the best area for bathing, but there are two other sandy areas. It is claimed that 200 different varieties of shells have been found here.
Facilities include toilets, a snack bar, a bar and a supermarket. Activities at the beach include bathing, shell collecting, kite-carting and fishing. The nearest railway station is Llanbedr, and is approximately 1 mile from the northern end of the beach. Dogs are allowed at all times.
