About Lihou Island#

Lihou Island is a small tidal island off the west coast of Guernsey in the Channel Islands. It is notable for its exposed position at low tide and its coastal habitats.

The island offers coastal walking, saltmarsh and rock-pool habitats and is a spot for seabirds and coastal plants; access is only possible around low tide by a short causeway or beach crossing. There are traces of historical use on the island which add interest for visitors exploring the shoreline.

Lihou has been managed for conservation in recent decades and is not intensively developed, with visitor access and activities organised to protect wildlife and archaeological remains.

Geographically it lies just off Guernsey’s western shore and is approached from the west coast of the main island; crossings must be timed to the local tide charts.

  • Tidal access: Access is tide-dependent, with a short causeway or beach crossing connecting it to Guernsey at low tide so visitors must plan around safe crossing times.
  • Conservation status: Important wildlife habitat supports shorebirds and saltmarsh plants, so much of the island is managed for conservation rather than development.

How to Get to Lihou Island#

From St. Peter Port (Guernsey), take a short drive or bus to the west coast at L’Eree or Lihou slipway. Cross only at low tide via the marked causeway-consult local tide tables and island council information before attempting the crossing.

Tips for Visiting Lihou Island#

  • Check tide tables before attempting the walk-Lihou is a tidal island accessible on foot only around low tide.
  • Wear sturdy footwear: the path is pebbly and can be slippery at the high-water margins.
  • Respect nesting birds and closed areas-parts of the island are protected for wildlife.
  • Ferries and guided walks are occasionally organized from Guernsey for those who prefer not to time the tides.
