Lihou is a small tidal island off the west coast of Guernsey, accessible via a cobbled causeway at low tide. Visitors should check tide times carefully to avoid being stranded. The island features diverse birdlife and the ruins of the Priory of St. Mary, making it suitable for nature enthusiasts and history buffs. A visit can be undertaken independently, exploring the island's trails and coastline, or with a guided tour to learn about its history and ecology. Accessibility is limited due to the tidal nature and uneven terrain. The approximate cost is low, mainly covering transportation to Guernsey. A typical visit lasts a few hours, depending on the tide and exploration interests. Seasonal restrictions may apply due to weather conditions.
