Abereiddy beach is famous for its black sand full of tiny fossils. Abereiddy nestles in a sheltered bay; it's one of Pembrokeshire's pebble backed storm beaches. All the pebble banks, like the one at Newgale, were created by a huge storm in 1859.
Nearby is the Blue Lagoon, a flooded slate quarry, regarded as an important geological feature. Abereiddy is on the northern coast of St David's Peninsula, about 5 miles away from St David's itself. The Pembrokeshire Coast Path passes the beach. The walk from Abereiddy to Porthgain is one of the best stretches along the entire coast path.
A Green Coast and Seaside Award beach. Nearest Information Centre, numerous cafes, pubs and shops can all be found in St David's 5 miles away. Dogs allowed.
