8 Best Coasteering Spots in Pembrokeshire (2025)

Abereiddy & Blue Lagoon

The iconic spot — flooded quarry, volcanic coastline, and the best cliff jumping in Wales.

Abereiddy combines everything that makes coasteering special into one location. The Blue Lagoon — a flooded slate quarry with impossibly turquoise water — offers cliff jumps from 3 to 8 metres in a relatively sheltered setting. The surrounding volcanic coastline has sea caves, tunnels, and natural arches. The dark rock and clear water create an otherworldly atmosphere. It's also where Red Bull Cliff Diving holds events, which tells you something about the jumping potential.

St Davids Peninsula (Porth Clais to Caerfai)

The birthplace of coasteering. The most varied stretch of coasteering coast in Wales.

This is where TYF invented coasteering in the 1980s, and the coastline between Porth Clais harbour and Caerfai Bay remains the gold standard. The geology is extraordinary — sea caves you can swim deep into, natural arches, blowholes that erupt when the swell hits right, and cliff jumps at various heights. Grey seals are almost guaranteed. Multiple operators use different sections, so you can return multiple times and have a completely different experience.

Stackpole & St Govan's

Dramatic limestone cliffs, sea arches, and the most beautiful coasteering backdrop in Wales.

The Stackpole coast is jaw-dropping — massive limestone arches, sea stacks, deep zawns (narrow inlets), and crystal-clear water over white sand. The coasteering here feels more dramatic than the St Davids section because the cliffs are bigger and the rock formations more architectural. The famous Green Bridge of Wales sea arch is nearby. Fewer operators work this stretch, so it's quieter and feels more exclusive.

Porthgain & Traeth Llyfn

Quiet, varied, and ends at one of the best pubs in Pembrokeshire. What more do you want?

The coast around Porthgain combines industrial heritage (ruined granite quarry works) with spectacular natural features. The coasteering here includes deep zawn swims, rock traverses, and jumps of various heights. It's less crowded than Abereiddy, more accessible than Stackpole, and finishes near the Sloop Inn — a legendary Pembrokeshire pub that serves fresh crab. The perfect balance of adventure and post-adventure reward.

Pwll Deri & Strumble Head

Remote, wild, and with the best chance of seal encounters in Pembrokeshire.

Strumble Head is the wildest stretch of the Pembrokeshire coast, and coasteering here feels properly adventurous. The seas around the headland are a marine wildlife hotspot — grey seals, porpoises, and occasionally dolphins. The coastline is rugged and less visited, with sea caves and zawns that feel genuinely unexplored. Fewer operators come here, which adds to the exclusive feeling.

Abercastle

A sheltered inlet with gentle jumps — the best introduction for nervous first-timers.

Abercastle is a tiny, sheltered harbour between St Davids and Fishguard that's perfect for easing into coasteering. The jumps are lower (2-4 metres), the water is calmer, and the setting is intimate rather than intimidating. Several operators use it for family sessions and beginner groups. It lacks the drama of Abereiddy or Stackpole, but for building confidence it's ideal.

Newport (Trefdraeth) Coast

North Pembrokeshire's quiet corner — excellent coasteering away from the St Davids crowds.

The coast around Newport is underused for coasteering compared to the St Davids area, which makes it feel more adventurous. The geology is different here — older, more fractured rocks creating a maze of channels, caves, and pools. Preseli Venture run sessions on this stretch and it's their home turf, so the guiding is expert. The Preseli Hills backdrop adds to the setting.

Solva & Newgale Coast

The middle ground — good variety, good access, and quieter than the famous spots.

The coast between Solva and Newgale doesn't have the name recognition of St Davids or Abereiddy, but it offers excellent coasteering with good variety — caves, jumps, traverses, and deep-water swimming. Solva itself is one of Pembrokeshire's prettiest harbour villages, with good cafés and pubs for post-adventure. Less dramatic than the top-ranked spots but more accessible and with a better après-coasteering scene.
