Îles Chausey Day Trip
A 50-minute ferry from Granville's port drops you into a different world: the Chausey archipelago, a scatter of more than 350 granite islets at low tide (just 52 at high tide) that forms France's largest tidal range spectacle and one of the least-visited island groups in the Channel. One small village, one hotel, no cars.
The Tides and the Landscape
Chausey has the second-greatest tidal range in Europe — up to 14 metres between low and high water — which means the landscape transforms completely every six hours. At low tide you can walk across sand causeways to neighbouring islets, discover rock pools thick with anemones and starfish, and feel genuinely far from mainland France.
The main island, Grande Île, is a 2 km strip of pink granite, wild thyme and sea lavender with a handful of fishermen's cottages, a small fort dating to François I and a lighthouse that has operated since 1861. The pace of life is determined entirely by the tides.
Wildlife and Swimming
Grey seals are resident in the archipelago year-round and are easily spotted from the rocks on the western shore of Grande Île, particularly at low tide. The waters around Chausey are a protected marine nature reserve, and the snorkelling in the clear shallows is exceptional for northern France.
Several sandy beaches on Grande Île are sheltered from the prevailing westerly winds and warm up quickly in summer — the water temperature reaches a surprisingly comfortable 18–20°C in July and August. Pack a picnic because dining options on the island are limited to one restaurant and a crêperie.
