Blue Lagoon Beach

Blue Lagoon beach is a mix of pebble, slate and sand and is an old slate quarry that flooded when one wall collapsed into the sea. The blue-green colour of the water comes from the slate and is some 25m deep,.

The lagoon is a favourite for adventure groups and coasteering, divers and has been featured in the Red Bull Cliff Diving world series.
