Abereiddy is a tiny hamlet on the northern coast of St Davids Peninsula, about 5 miles away from St Davids itself.

The Pembrokeshire Coast Path passes the beach and the walk from Abereiddy to Porthgain is one of the best stretches along the entire coast path.

What's in Abereiddy?


Abereiddy beach is famous for its black sand full of tiny fossils and is perfect for other activities such as fishing and kayaking and seal watching in the autumn.

The Blue Lagoon is a favourite for adventure groups practising coasteering, and in 2012 and 2013 the lagoon took centre stage as the only UK stage for the Red Bull Cliff Diving world series. Divers from around the world compete in 8 exotic locations from Brazil to Thailand and Pembrokeshire! Diving from a platform 27meters above the water, it’s not for the faint-hearted.

Food & drink

An ice cream van is normally available in the car park during the summer months. The nearest pub and restaurant are in Porthgain, 2 miles north via the cliffs and coast path and 2.5 miles by car.


There are plenty of small campsites and caravan sites nearby. There are some quality B&Bs and hotels in the vicinity and in nearby St Davids. Self-catering cottages can be found all across the St Davids peninsula, including some of the cottages on Abereiddy beach itself. Search for accommodation.

Getting to Aberieddy

Abereiddy is on the route of the Strumble Shuttle. The coastal bus service hugs the coast from Strumble Head near Fishguard to St Davids and is a great way to enjoy the National Park without a car.

Did you know...

Abereiddy was involved with slate with a small quarry just north of the beach. Initially, the slate was exported across Abereiddy beach, but later through a tramway to the harbour at Porthgain a couple of miles to the north. Today the quarry is flooded and known better as The Blue Lagoon

The Blue Lagoon is 25m deep but despite the name, the water is always a distinct greenish hue, owing to the mineral content within the quarry.

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 was only abandoned after a flood in the early 20th century.
