This was the first marine nature reserve created in France, established in 1974.
The trail is monitored by lifeguards during the peak season to ensure safety and environmental compliance.
The reserve protects over 1,200 animal and plant species native to the Mediterranean.
Posidonia seagrass meadows located here are protected as they are vital oxygen producers and carbon sinks.
The water depth along the snorkel trail ranges from 0.5 to 5 meters.
The reserve's strict 'no-take' zone has resulted in a measurable increase in the size and population of local fish species like the dusky grouper.
The Sentier Sous-Marin de Cerbère-Banyuls is a dedicated snorkeling trail located within France's first marine nature reserve. The 250-meter buoyed path allows swimmers to explore diverse Mediterranean marine ecosystems near the surface. Visitors follow a marked route along the Plage de Peyrefite, equipped with floating buoys that provide educational information about the underwater environment. The reserve spans 6.5 kilometers of coastline between the towns of Banyuls-sur-Mer and Cerbère. It protects a wide variety of habitats, including Posidonia oceanica seagrass meadows and rocky reefs. Fishing is strictly prohibited within the reserve's core zone to ensure biodiversity preservation. The seabed transitions from shallow rocky areas to deeper sections, supporting species like dusky groupers and barracudas.

Bring a high-quality snorkel mask and fins, as rentals may be limited during peak capacity.
Wear a rash guard or light wetsuit, as the water temperature can be brisk even in mid-summer.
Apply reef-safe sunscreen at least 20 minutes before entering the water to protect the ecosystem.
Do not attempt to swim outside the marked buoyed area, as boat traffic can be hazardous.
The snorkeling trail is seasonal and typically operates only from June through September.
Do not touch, feed, or disturb any marine life. Do not collect shells, stones, or coral samples.
