Ile d'Oleron

Oleron is about thirty kilometres long, the largest French island on the Atlantic side, with pine forest and dunes on the west coast facing open ocean and oyster country in the sheltered east. At Le Chateau-d'Oleron, the old oyster cabins along the channels were repainted in strong colours from the 1990s and taken over by artists and craftspeople, making a working port that is also a row of studios. Oyster farming here uses claires, shallow clay basins where oysters finish and take on a greener tint from algae. The Fort Boyard sits offshore, and the lighthouse of Chassiron in the north has two hundred and twenty-four steps.

What you actually see

• The painted oyster cabins - colourful huts turned studios at Le Chateau.
• The claires - shallow clay finishing basins in the marshes.
• Chassiron lighthouse - a striped tower at the northern point.
• The west coast dunes - pine and sand facing open ocean.

When to go

May to September; the bridge is free, so summer traffic is heavy. Oysters are sold year-round with the main season in autumn and winter. Atlantic surf and rips are strong on the west coast.

Honest expectations

Being toll-free makes Oleron busier and more built-up than Re in summer. West coast swimming has serious rip currents and is only safe at supervised beaches. Accommodation books out in August.

Nearby
