History of the Blue Lagoon
The Blue Lagoon in Pembrokeshire wasn’t always a dreamy destination for adventurers and cliff divers. These days, it’s a popular day trip from Cardiff, but it actually has a fascinating backstory.
It started as St. Brides Slate Quarry, a busy slate mining site in the 19th century when Pembrokeshire’s coast was dotted with quarries. Slate workers carved slabs out from the cliffs here, and the slate was transported to Porthgain on a tramway and then shipped to the world.
When the quarry closed around 1910, local fishermen had an idea. They blasted open the seaward wall, allowing the quarry to flood, creating a sheltered spot where they could safely moor their boats. So, the Blue Lagoon was born! Now, the mineral-rich sediment from the slate has given this lagoon its famous turquoise color, making it one of the most striking places on the Pembrokeshire Coast.
This old quarry has seen a lot of history and even hosted the Red Bull Cliff Diving series, where brave divers took the leap from dizzying heights into the cool waters of the Blue Lagoon. It’s not every day you can explore a piece of history that’s also the perfect place for cliff diving or just a refreshing dip.

The best time to visit
Wondering when to visit the Blue Lagoon Pembrokeshire? This stunning spot is part of the Pembrokeshire Coast National Park and is worth visiting any time of the year, though each season has its own charm.
Spring and early summer (April to June) bring mild weather and vibrant wildflowers along the Pembrokeshire Coast path, making it perfect for a scenic walk with fewer people.
In July and August, the Blue Lagoon gets quite popular, so you’ll find a livelier atmosphere, great if you’re up for a more social vibe but maybe a bit crowded if you’re after peace and quiet.
For an extra touch of magic, try visiting in the late afternoon during early autumn. Fewer people, soft light, and sunsets over the lagoon are pure bliss. The Blue Lagoon is open year-round, but remember that if you’re planning to dive in, the water can be brisk outside of summer!
For the ideal balance of peaceful views and fewer visitors, a crisp autumn day might just be your best bet.
How to get to the Blue Lagoon in Pembrokeshire
Located on the north coast of the Pembrokeshire Coast National Park, it’s best reached by car. The closest parking area is at Abereiddy Beach, just a short 5-10 minute walk to the lagoon itself. For parking, you’ll pay around £4 for the day, which is a fair deal for such a unique experience.
The roads leading to the Blue Lagoon are narrow and winding, typical of the Pembrokeshire Coast. Take it slow and enjoy the scenic drive! Once parked, it’s a quick, flat walk along the coastal path to the lagoon, with beautiful views over the cliffs as you approach.
If you don’t drive, getting here can be a bit trickier. There’s a limited local bus service (the 404 bus) that stops at a junction near Abereiddy Beach, running between St. Davids and Fishguard. This bus isn’t frequent and only operates in peak seasons, so it’s worth checking schedules and considering a taxi if public transport doesn’t fit your plans.
Alternatively, if you’re staying nearby in St Davids or Porthgain, a taxi might be your best option to make sure you get there hassle-free.
