The full story

Standing two kilometres offshore on Jersey's vast south-east tidal plain, Seymour Tower (1782) is reached on foot at low water across a moonscape of gullies, oyster beds and rockpools. Guided walks visit it; the adventurous can book an overnight stay.

Good to know

Never attempt the crossing unguided — the tide here comes in faster than walking pace.
