The ideal summer outing

The cruises are definitely a must when you come to Saint-Nazaire in the summer!

  • There could hardly be a nicer way to spend two hours than aboard a ship sailing along the coast, beaches and cliffs…
  • How many opportunities will you have to sail underneath the huge Saint-Nazaire bridge or in close proximity to an amazing granite lighthouse?
  • Photographers will have a field day with all the beaches, coves, cliffs, but also the shipyard and harbour terminals…

Several cruises to choose from

Cruises take place on ships having a capacity of 150 seated passengers. You will be accompanied by professional guides. Live commentary in French. According to the tide and the weather, tours can vary slightly.

Duration: approx. 1½ – 2 hours.

2-hour daytime cruise: “Saint-Nazaire sur Mer”

The “Saint-Nazaire sur Mer” tour takes you along the beaches and cliffs which make the coast in Saint-Nazaire so attractive. The ship sails along tiny coves, rocks and cliffs, sandy beaches… and offers unhindered views of a largely unspoilt and wooded coast. After turning back, the ship sails upstream on the Loire River, past the shipyard and some of the impressive harbour terminals, but also underneath the Saint-Nazaire bridge. A great experience!

1½-hour cruise: “Accords maritimes”, musical cruise

Embark on an unexpected journey to Saint-Marc-sur-Mer. Two musicians and a narrator tell you about the multifaceted history of Saint-Nazaire through the coastal landscapes. An opportunity to experience the links between the maritime city and the world.
