Grassholm Island - gannets galore
Eight miles off the coast lies Grassholm, home to one of the world's largest gannet colonies! Watching these magnificent seabirds is an awe-inspiring experience.
Approximately 39,000 pairs breed on this tiny, remote island. These magnificent seabirds, with their striking plumage, piercing blue eyes, and an impressive wingspan, dominate the landscape. Watching their aerial displays and busy nesting activities is a breathtaking experience.

While gannets are the stars, Grassholm also hosts smaller populations of guillemots, razorbills, fulmars, kittiwakes, and a few shags. They share the cliffs and ledges with the gannets, adding to the island's vibrant seabird community.
You may also spot Atlantic grey seals, playful dolphins, porpoises, and occasionally larger whales can be spotted.
How to visit Grassholm
Grassholm is a strictly protected RSPB Reserve. The best way to witness its wildlife spectacle is through organised boat trips.
Thorne Island: A Fortified Gem
Thorne is a small rocky island providing habitat for nesting seabirds and occasionally seals and situated just off the coast of Angle. It is dominated by its star-shaped Victorian fort, a Grade II listed building. Built in the 1850s as a coastal artillery fort to defend the Milford Haven Waterway against a potential French invasion.
Take a boat trip
You can't land on the island for casual visits. However, boat tours offer a great way to view Thorne Island's impressive fort from the water and learn about its history as you cruise around it. Keep an eye out for seals sometimes basking on the rocks and seabird colonies nesting around the island.
And yet more Pembrokeshire islands
St. Margaret's Island is a site of a medieval monastery, offering history and quiet beauty.
St. Margaret's holds the atmospheric remains of a medieval monastery. While not grand in scale, the historical significance and peaceful setting create a unique charm.
The island's limestone was heavily quarried in the past, with quarriers' houses still visible.
Though small, it's a haven for seabirds; guillemots, razorbills, and cormorants nest on its cliffs, along with various types of gulls. Look for the flashes of colour as puffins sometimes visit too.
The Bishops and Clerks is a group of rocky group of islets and haven for seabirds.
This cluster of rocky islets stands as a striking sentinel off the Pembrokeshire coast. Their rugged shape and exposed location make them a distinctive seascape feature.
'Bishop' refers to the largest rock, while the smaller rocks are the 'Clerks.' These islets are crucial nesting sites for gannets, guillemots, razorbills, and other seabirds.
The best way to experience the Bishops and Clerks is by boat. Many trips to Skomer and Ramsey Island pass nearby, offering excellent viewing of the rocks and their boisterous bird colonies.
