Visiting RSPB South Stack Cliffs Reserve on Holy Island, Anglesey, is an unforgettable experience. Perched above the Irish Sea, this dramatic landscape offers a blend of natural beauty, rich wildlife, and historical intrigue.
Nature & Wildlife
South Stack is renowned for its seabird colonies, with up to 9,000 birds nesting on the cliffs during breeding season. Species include puffins, guillemots, razorbills, kittiwakes, and fulmars. The reserve is also a stronghold for the red-billed chough, a rare crow with striking red legs and a curved bill. Visitors often spot these birds feeding near the visitor centre or soaring along the cliffs .
The heathland supports unique flora like the endemic spatulate fleawort and fauna such as silver-studded blue butterflies, adders, and common lizards. Marine life sightings may include bottlenose dolphins, harbour porpoises, and even minke whales .
South Stack Lighthouse
Built in 1809, the South Stack Lighthouse stands on a small island accessed via over 390 stone steps and a bridge. While the lighthouse was closed during one visitor’s trip, it typically offers tours that include the engine rooms and panoramic views from the top.
Walking & Exploring
The reserve features several trails, including the Anglesey Coastal Path and the Cybi Circular Walk. These paths offer stunning views of the cliffs and sea, with opportunities to explore heathland and spot various bird species. Ellin’s Tower, a Victorian structure, serves as a visitor centre with telescopes and information about the local wildlife.
Prehistoric Roundhouses
Just a short walk from the main RSPB visitor area lies Ty Mawr Hut Circles, a remarkable group of well-preserved prehistoric roundhouses dating back to the Iron Age and Roman periods. These stone structures offer a fascinating glimpse into ancient life on Holy Island, with the remains of walls, doorways, and hearths still clearly visible. The site sits on open heathland with sweeping views across to South Stack and the Irish Sea, making it a scenic and historically rich detour for walkers. Interpretive panels help bring the ancient settlement to life, and the peaceful setting offers a real sense of stepping back in time.
