LOCATION ~ ABEREIDDY
Abereiddy has a small beach which has black sand. A large car park adjoins the beach, in the summer an ice cream van can usually be found. The beach also has public toilets. The Pembrokeshire Coast Path gives fine walking in both directions.
Ruins of a small group of slate houses known as The Street remain near the beach. These were houses built for the quarry workers of the Blue Lagoon and were only abandoned after a flood in the early 20th century.
Nearby are the ruins of the ‘Blue Lagoon’, a small slate quarry, now flooded by the sea having broken in. Initially slate was exported across Abereiddi beach, but later through a tramway to the harbour at Porthgain a couple of miles to the North. Although a small quarry, it operated a steam-hauled lift.
The Blue Lagoon is 25m deep and despite the name, the water is always a distinct greenish hue, owing to the mineral content within the quarry.
Red Bull Cliff Diving World Series location in 2012, 2013 & 2016. A selection of the world’s best divers dived from a man-made platform, 27 metres for the men and 20 metres for the women, into the Blue Lagoon.
