Complete guide to the Îles du Ponant

Everything you need to know about the 15 islands off the French Atlantic coast: how to get there, when to go, what to see.

What are the Îles du Ponant?

The Îles du Ponant are a group of 15 islands along the French Atlantic and Channel coasts, from Charente-Maritime to Finistère. They share three fundamental characteristics: a permanent population, municipal status, and no fixed link to the mainland — no bridge, no road. To reach them, there is only one way: the sea.

The Îles du Ponant association, founded in 1971, brings together these 15 island gems and works to maintain active island communities and preserve their unique heritage.

The 15 islands, department by department

  • Île de Sein — almost flat, heroic during World War II
  • Île de Batz — exotic gardens and mild microclimate opposite Roscoff
  • Île de Bréhat — the "flower island", pink granite and subtropical climate
  • Glénan archipelago — turquoise waters nicknamed the "French Caribbean"

Morbihan (6 islands)

When to go?

High season runs from mid-June to mid-September. Crossings are more frequent but the islands are busier. Fares are generally higher.

Low season (October to May) offers a more authentic experience: fewer people, spectacular winter light, but reduced ferry schedules and more unpredictable weather.

Spring (April–June) is often the best compromise: pleasant weather, flowers in bloom, and regular crossings without the summer crowds.

How to book?

Each ferry company has its own online booking system. For peak periods (May bank holidays, July–August), we strongly recommend booking in advance, especially if you're travelling with a vehicle.

Check our company pages to go directly to each operator's booking website.

Practical tips

  • Vehicles: only some routes accept cars (Belle-Île, Groix, Yeu). Many islands are car-free — bring or rent a bike instead.
  • Bikes: generally accepted on most crossings, with a supplement of €3 to €18.
  • Luggage: pack light and easy to carry — quaysides can be steep.
  • Seasickness: some Iroise Sea crossings (Ouessant, Sein) can be rough. Take precautions.
  • Cash: bring cash — ATMs are rare on smaller islands.
