Île de Berder

Drop anchor off this quietly magical 23-hectare island in the Gulf of Morbihan, linked to the mainland village of Larmor-Baden by an 80-metre submersible causeway that reveals itself at low tide. Once ashore, a 2.5 km coastal path circles the entire island, giving you views across the scattered islands of the gulf. It's a small, unhurried place that rewards those who time the tides right.
