The Blue Lagoon in Abereiddy, Wales is a small oasis on the west coast of the United Kingdom. Originally a slate quarry, it was shut down in 1910. The mine was flooded (on purpose) by local fisherman who blasted a narrow channel in the seaward side of the quarry, which allowed the ocean to flood the pit and provide shelter for their boats. The fishing industry has all but disappeared from Abereiddy Bay, and these days the lagoon is more popular for swimming, diving and exploring than as a boat harbor.

Evidence of the industrial era still stands around the lagoon, and the remaining slate walls are popular diving platforms. Even though it was considered a small quarry, The Blue Lagoon is pretty deep —- 25 meters according to the Pembrokeshire National Park. The water is a recognizable green-blue hue, which gets its color from the mineral content of the submerged slate.

How to get there:

The Blue Lagoon is in Abereiddy, a small hamlet in Pembrokeshire county in south-west Wales. Park at the Abereiddy Beach car park, and walk the short path to the lagoon.

What to consider

  • Parking is free at the beach, about a 7-minute walk from the Lagoon — the path is also suitable for wheelchairs and strollers.
  • To get to the diving platforms, you have to swim across the quarry.
  • Wetsuits aren’t necessary, but they’re a nice addition.
  • You can also paddle a kayak or boat from the beach through the channel and into the lagoon.
  • If you’re still looking for things to do after you’re done in the lagoon, Abereiddy beach is a black sand, pebble and shingle beach loaded with fossils for the picking — but only at low tide.
  • The Blue Lagoon is within Pembrokeshire Coast National Park -— named the second best coastal destination in the world by National Geographic in 2011.
