Where to swim with dolphins in France

6 places in France and its overseas territories, from the Indian Ocean to the Mediterranean: seasons, species, whether you can swim (supervised, tolerated or not allowed) and how to choose an operator that respects the animals.

6spots in FranceFrom €35for observationYear-roundin Reunion Island

France has some of the richest dolphin and whale waters in Europe, thanks to its overseas territories (Reunion Island in the Indian Ocean, Guadeloupe and Martinique in the Caribbean) and protected areas in mainland France (the Pelagos Sanctuary, Mont-Saint-Michel, Brittany, the Basque coast). But commercial dolphin swims are only allowed in a few places, and always under strict conditions.

Here are the 6 best placesto see or swim with dolphins, ranked by how often they're seen and whether you can swim.

The 6 spots

From the best to the easiest to reach

Reunion Island

Season

Year-round (dolphins), June-October (+ whales)

Species

Spinner dolphins, Indo-Pacific bottlenose dolphins

The island this site is all about. Boat trips leave from Saint-Gilles with operators who have signed the responsible-watching charter, and your chances of seeing dolphins are very high year-round. You get in the water with mask, snorkel and fins when the dolphins are calm and conditions allow.

In practice

About €90 per person for 2-3h from Saint-Gilles harbour. Book 1-2 weeks ahead in high season. A strict official charter applies (100m distance, no chasing, no diving on top of the group).

Côte d'Azur, Provence, Corsica

The Mediterranean and Corsica

Season

June to September

Species

Striped dolphins, bottlenose dolphins, Risso's dolphins

The Pelagos Sanctuary covers 87,500km² between France, Monaco and Italy. Dolphins are common there in summer, and boat trips leave from Antibes, Cannes, Nice, Toulon, Saint-Mandrier, Calvi and Ajaccio. To protect them, nobody offers swimming with dolphins in the Mediterranean.

In practice

Half-day boat trips cost €50-90. Choose operators with the Pelagos 'High Quality Whale Watching' label. June-September gives the best chance of sightings.

Spot 03Observation only
Morbihan, Concarneau

Brittany

Season

June to September

Species

Bottlenose dolphins (a resident population), common dolphins

The Gulf of Morbihan and Concarneau bay are home to resident bottlenose dolphin populations. Watching trips are run by marine biologists or scientific groups, sometimes with a hydrophone so you can hear the dolphins, and with a strict ethical approach.

In practice

Half-day trips cost €40-70 depending on the operator. The Atlantic can be choppy, so bring seasickness tablets. Season: June-September.

Spot 04Supervised swimming (the only mainland France site)
Hendaye, Saint-Jean-de-Luz, Capbreton

The Basque Coast

Season

June to September

Species

Common dolphins, bottlenose dolphins, sometimes minke whales

One of the very few places in mainland France where specialist operators can take you swimming with dolphins. You get in when conditions allow (calm dolphins, a flat sea), under strict Atlantic rules.

In practice

A supervised swim trip costs €80-150 for 3-4h from Hendaye or Capbreton. You must be a confident snorkeller. Book 2-3 weeks ahead in July-August.

Mont-Saint-Michel Bay

Season

Year-round (a resident population)

Species

Bottlenose dolphins (one of Europe's largest populations)

The bay is home to a resident population recognised as one of the largest in Europe, tracked for years by local associations. You can watch them from the coast (Cap Fréhel, Pointe du Grouin, the bay itself) or on boat trips from Cancale, Granville or Saint-Malo.

In practice

Boat trips cost €35-65 for 1h30 to 3h. Bring binoculars. The strong currents mean no commercial swimming with dolphins.

Spot 06Supervised swimming
Guadeloupe, Martinique

The French Caribbean (French West Indies)

Season

Year-round

Species

Pantropical spotted dolphins, Fraser's dolphins, bottlenose dolphins

The coasts of Guadeloupe and Martinique offer excellent conditions for watching, and sometimes swimming with, dolphins, in 26-28°C water year-round. Boat trips departing from Pointe-à-Pitre, Sainte-Anne (Guadeloupe), Le Marin, Trois-Îlets (Martinique).

In practice

Trips cost €60-110 depending on the package (watching only or supervised swimming). The dry season (December-May) has the best sea conditions.

Frequently asked questions

Swimming with dolphins in France: your questions answered

Where can you legally swim with dolphins in France?
Three areas offer supervised swimming: Reunion Island (under a strict charter), the Basque coast (specialist operators) and the French Caribbean (Guadeloupe, Martinique). In the Mediterranean, Brittany and Mont-Saint-Michel Bay, nobody offers it, to protect the resident dolphins.
What's the best spot to swim with dolphins in France?
Reunion Island, without hesitation: a very high chance of sightings year-round, easy boat trips from Saint-Gilles, a responsible-watching charter that reputable operators take seriously, and humpback whales too in season (June-October).
How much does a dolphin swim outing cost?
In Reunion Island, about €90 for the full trip. In the Caribbean, €60-110. On the Basque coast (the only site in mainland France), €80-150 depending on length. Watching-only trips in the Mediterranean and Brittany start at €35-50.
What's the best season?
In Reunion Island and the Caribbean, year-round. In mainland France, mainly June to September (calmer water, and dolphins spend more time at the surface). In the Pelagos Sanctuary, sightings peak in July-August.
Do you need to be a strong swimmer for supervised swimming?
Yes, you need to be a confident snorkeller in Reunion Island and on the Basque coast. In the Caribbean, most operators accept beginners, as they provide a buoyancy vest. For children, check the minimum age with each operator (often 8-10).
How do you choose a responsible operator?
Check that they've signed the local watching charter (the official charter in Reunion Island, the Pelagos Sanctuary's 'High Quality Whale Watching' label in the Mediterranean, association certifications in Brittany). Choose operators with marine biologists on board, and avoid any that guarantee you'll get in the water no matter what.
Can you touch or feed the dolphins?
Absolutely not. The charter requires you to let the dolphins come to you, with no chasing, no noise and no touching. Fines can run to several hundred euros, and operators can lose their licence.
Can you see dolphins from the coast?
Yes, some areas offer regular sightings from the shore: Cap Fréhel and Pointe du Grouin (Brittany), the Basque corniche, the Saint-Leu cliffs (Reunion Island), Cap d'Antibes (the Mediterranean). Bring binoculars and go at quieter times (9am-11am).
