Shell Island
Gwynedd
Shell Island (Mochras) is a peninsula that becomes an island at high tide, reached via a causeway and home to a large campsite. The beaches here are backed by dunes and the site is famous for the thousands of different shell species found on its shores, making it a superb beachcombing destination. The views north to the Snowdonia mountains and south along Cardigan Bay are stunning.
Shell Island is a private campsite and day visitor site; access requires payment. Dogs are welcome. Shell Island is not included in the Gwynedd PSPO restriction list, so no seasonal ban applies. Year-round dog access on the beach.
