The best snorkeling areas in South France are the rocky parts of the coast. It is undoubtedly in the Var region that the best snorkeling spots of South France are located. Between la Seyne-sur-Mer and St Tropez, you’ll find many coves, bays, and rocky beaches to explore, like in Anse Magaud, Plage de Brégançon, Plage de Jovat, and Calanque du Four à Chaux.
On the Giens peninsula, you can also discover the Archaeological Site of Olbia, where an ancient Roman quay and a 19th-century wreck rest a few meters only from the beach.
This region also hosts the Port Cros National Park, considered as the French snorkeling Mecca. This small island, which has been a National Park since 1967 (the oldest marine protected area in the Mediterranean), has sea beds that are among the best-preserved and richest in fish.
Some spots (Plage de la Palud, but also Anse de la Fausse Monnaie) are without equal and will delight even the most experienced snorkelers.
There, you’ll have good chances to meet huge common dentex, greater amberjack, dusky grouper, and brown meagre, some species that are almost impossible to spot at snorkeling depth elsewhere in South France.
Although also located in Port Cros National Park (which was extended in 2012), the island of Porquerolles is less full of fish, because fishing remains authorized on a large part of its coastline.
Some of the best places on the island to snorkel are Calanque du Brégançonnet, Plages du Langoustier, and Cap des Mèdes, but you can also find decent snorkeling along the rocky edges of the famous Plage Notre-Dame and Plage d’Argent.
The Calanques range (between Marseille and Cassis) boasts a magnificent rocky shore with crystal clear waters, but not that fishy. In fact, despite the Calanques area is part of a National Park since 2012, fishing is still allowed in 90% of its perimeter, including the most popular Calanques of Sormiou, Sugiton, Port Pin, and En Vau.
Close to Marseille, Plage du Cap Rousset in Carry-le-Rouet and Anse du Petit Mugel in La Ciotat are better options. The eastern part of the French Riviera, consisting mainly of rock, offers some spots of varying quality.
In Languedoc, characterized by long sandy beaches, opportunities to practice snorkeling are becoming rarer. The Cap d’Agde and Sète are home to some decent spots, including La Plagette and Plage du Lazaret, but the most amazing snorkeling spots around are not in the sea.
The Etang de Thau, a lagoon about twenty kilometers long separated from the sea by a coastal strip stretching between Agde and Sète, is a unique opportunity to discover an exceptional aquatic life, including two species of seahorses, several species of pipefish and nudibranchs, in a few meters of water. To get the best chances to spot them, head to the Ponton de la Bordelaise, just 5 minutes from Sète.
At the western end of the French Mediterranean coast, the Côte Vermeille, between Perpignan and the Spanish border (you can check our page about snorkeling in continental Spain here), is another snorkeling hotspot in France. These few kilometers of rocky coastline are home to the country’s oldest marine reserve (the Cerbère-Banyuls national nature reserve, created in 1974). Plage de Peyrefite, in particular, is full of fish.
A large number of snorkel trails have been set up along the French coast. With their immersed educational panels, they are an original way to explore the sea bed and to discover the Mediterranean’s biodiversity. Among the most popular snorkel trails is Plage de la Palud in Port Cros, Plage de Peyrefite in Cerbère, Anse Magaud near Toulon, and La Plagette in Cap d’Agde.
The Mediterranean is a relatively small and enclosed sea (1% of the world’s ocean surface) but is a major source of biodiversity. It is estimated that the Mediterranean contains 8% of the world”s sea life, with an endemism rate of nearly 30%.
Neptune grass seabed, in particular, provides a remarkable environment that is simple to explore from the French coast. Although it is easy to come across ornate wrasse, sargo, cuttlefish, and starfish in the French Mediterranean waters, you may also spot moray eels or small dusky groupers in certain areas.
If you are planning a snorkeling trip to Southern France, we recommend you to take with you great Europe and Mediterranean Marine Fish identification guide, a comprehensive guide that includes all the marine fish species that may be encountered in the Mediterranean up to 50m depth.

The Mediterranean climate is mild and sunny, and the temperatures are generally clement. On the coast, average temperatures range between 70 to 80°F (20 to 25°C) from June to September, and from 55 to 70°F (14 to 20°C) the rest of the year.
July/August is the peak period for tourists in the region, and you can expect high visitor numbers on some parts of the coast.
Water temperature varies between 65 to 75°F (18 to 24°C) from July to October, and around 60°F (15°C) in May/June. Outside these months, snorkeling is limited by cooler water temperatures, unless you have an adapted wetsuit.
Even during summer, we recommend wearing a rashguard, which will protect your back and shoulders from the strong UV radiations that occur in the Mediterranean.
Our selection of the best rashguards and wetsuits for snorkeling may help you to make your choice!
The wind, blowing in gusts over some parts of the coast, should be taken into account before a snorkeling trip in the Mediterranean. It can lead to dangerous conditions in the sea (waves), but which are also less pleasant (cold).
