Lihou Island

Lihou lies off Guernsey's western tip and is reached on foot across a cobbled causeway that only clears at low tide, which means the island is accessible for a few hours at a time on published dates. The ruins of a Benedictine priory of the twelfth century stand on it, along with a house used for residential groups, and the surrounding reefs and pools are a Ramsar site rich in marine life.

What you actually see

• The tidal causeway - a cobbled crossing open only for a few hours at low water.
• The priory ruins - the twelfth-century Benedictine remains.
• The rock pools - the Ramsar reef and pool system around the island.
• The isolation - an island cut off for most of every day.

When to go

Causeway opening times are published and vary through the month; check before going. April to September is the season for the pools and birds. Winter storms close the crossing.

Honest expectations

Getting cut off by the tide is a real risk and people are caught out every year. There are no facilities on the island. The causeway is uneven and slippery.
