Seymour Tower stands on a rock about two kilometres off Jersey's southeastern corner, a square granite tower built in 1782 against French landings, and it can only be reached on foot across the reef at low tide with a guide, because the water comes back fast across a very large area of flat ground. The tower can be stayed in overnight, which means being cut off by the sea for hours on either side.
What you actually see
- The tower - the square granite building of 1782 on its offshore rock.
- The reef walk - the guided crossing over the exposed seabed at low tide.
- The tidal range - one of the largest in the world, uncovering a vast area.
- The overnight stay - the option of being cut off in the tower by the tide.
When to go
April to September is the main season for guided walks. Crossings run to the tide, not a timetable. Winter walks are occasional.
Honest expectations
Going without a guide is genuinely dangerous and people have drowned on this reef. Crossings depend on the tide and cancel in poor visibility. The tower has no electricity or running water.
Nearby
La Rocque is on the shore, and Gorey is north.
