Shell Island has the largest camp site in the UK with some 300 acres of camping space for tents only. The site usually allows parking for day visitors, and can be reached across a causeway from Llanbedr. This floods on some high tides cutting off vehicular access, although access on foot from the south is always possible. The cut-off times are shown on a board at the start of the causeway.
The shore varies from rocky to sandy, with some impressive sand dunes to the south. This is the best area for bathing, but there are other sandy areas. It is claimed that 200 different varieties of shells have been found here.
Facilities include toilets, a bar and a supermarket. The nearest railway station is Llanbedr, and is approximately 1 mile from the northern end of the beach.
Dogs are allowed at all times.
