Visit Worm's Head Tidal Island



A rocky sea serpent hides caves, blowholes, and a spectacular natural bridge.

Given the name “Wurm” (Dragon) centuries ago by Vikings for its snaking serpentine profile, the tidal island now known as Worm’s Head has inspired visitors since antiquity, and once trapped a terrified young Dylan Thomas.

Connected to the mainland by a two-mile-long causeway which slips beneath the waves at high tides, Worm’s Head holds many natural wonders for the adventurous explorer including natural caves and blowholes, but the crowning glory is the spectacular, jagged Devil’s Bridge which connects the Inner Head to the Low Neck.

On the outermost outcrop, a nearly inaccessible cave fascinated Henry VIII’s official antiquarian, who wrote of tales of hidden passageways and secret doors to be found deep within the island. Excavations in the modern era have long since disproved that romantic fantasy, but did uncover a minor treasure trove of bones and ancient stone tools.

The Worm’s Head is now protected as a National Nature Reserve by the National Trust and the Countryside Council for Wales. It is home to huge colonies of nesting seabirds, which can affect the accessibility for human visitors during the spring and summer months.
