A peaceful island facing Roscoff

The Île de Batz stretches out just opposite Roscoff, separated from it only by a narrow channel. The crossing takes just a quarter of an hour, but the change of pace is immediate: here, people get around mostly on foot or by bike, between vegetable fields, dry-stone walls, fishermen’s cottages and small white sandy beaches.

The island is inhabited all year round. It lives from fishing, farming and, in summer, from welcoming visitors who come to enjoy its mild climate. One day is enough to go round it and discover its main sights without rushing.

The lighthouse: 198 steps to a vast view

Built in 1836, the Île de Batz lighthouse rises to 44 metres. Its 198 steps take some effort, but the reward is worth it: a panorama over the whole island, Roscoff, the Léon coast and the reefs scattered across the sea. An exhibition set up at its base in 2018 tells the story of the lighthouse and its keepers.

The lighthouse is open in season, with opening times that vary through the year: check with the island’s tourist office before climbing.

The Georges Delaselle garden, a palm grove in Brittany

In 1897, Georges Delaselle, a Parisian insurer with a passion for botany, fell for the island and bought windswept plots of heathland at its south-eastern tip. There he created a garden where hundreds of species from Africa, Asia, the Americas and Oceania now grow: a palm grove, a cactus garden, a lawn of cordylines.

During the first works, a Bronze Age burial ground was even uncovered. Owned by the Conservatoire du littoral since 1997 and awarded the Jardin remarquable (Remarkable Garden) label in 2006, the garden was badly hit by Storm Ciarán in November 2023 and has been recovering ever since.

Round the island on foot or by bike

The coastal path goes all the way round the island, leading from one cove to the next, with ever-changing views of the reefs and the mainland. On foot, allow the whole day with breaks; by bike, the tour is quicker, along quiet tracks. Bikes can be hired on the island.

Along the way, don’t miss the Sainte-Anne chapel and the white sandy beaches, ideal for a swim when the sea is calm.
