Home to France's leading fishing port, Boulogne-sur-Mer is a must on any tour of the Opal Coast and is considered its capital. You'll need several days to see it all, especially with a visit to Nausicaá, Europe's largest aquarium, which takes an average of 5 hours.

Yes, and it's even one of the coast's best family stops thanks to Nausicaá. The ramparts are pushchair-friendly.

Information about the town
Close to Cap Gris-Nez, Boulogne-sur-Mer is one of the classic towns of northern France, alongside Calais, Wimereux and Hardelot. A real fishing town for decades, it draws thousands of visitors every year for its architecture, history and giant aquarium. Boulogne-sur-Mer attracts city-dwellers from Paris or Lille wanting a breath of sea air and some water sports, especially in summer. Its closeness to Le Touquet (45 minutes' drive) is an asset: staying at a hotel in Boulogne-sur-Mer and spending a few days in Le Touquet is a common pairing.
