Seymour Tower
An 18th-century watchtower on the tidal flats of the southeast coast. During extreme low tides, you can walk two kilometres across the seabed with a licensed guide, exploring rock pools and gathering shellfish.
Jersey's tidal range can reach 12 metres, making it one of the regions with the greatest tidal ranges in the world. On the southeast coast, at low tide, several square kilometres of seabed known as the Moonscape are exposed. Seymour Tower was built in 1782 on a reef about 2 kilometres offshore. During spring low tides, visitors can reach it on foot across the intertidal zone, led by a licensed guide. Along the way, you can observe crabs, starfish and seaweed in the rock pools. Guides also offer experiences such as shore foraging and oyster gathering. The tide rises extremely quickly, so never attempt the crossing alone. Waterproof footwear is essential, and advance booking is required.
