A marked trail in the heart of the Cerbère-Banyuls Marine Reserve
The Cerbère-Banyuls Underwater Trail immerses visitors in an exceptional protected site. Managed by the Pyrénées-Orientales Department, a long-standing actor in the preservation of the Catalan coastline, it is part of the marine nature reserve created in 1974—the first of its kind in France. Along 6.5 kilometres of coastline, this protected area hosts a wide diversity of Mediterranean ecosystems. The marked trail offers an accessible, self-guided way to explore it without technical constraints.
Five educational stations to discover at the surface
The underwater trail extends over 250 metres and is organised around 5 distinct observation stations. Each stop highlights a characteristic Mediterranean ecosystem: beach pebbles, seagrass meadows of Posidonia, rocky boulders, fissures, and drop-offs. Submerged, numbered information panels guide your interpretation of the underwater landscape. Buoys fitted with handrails mark the route, allowing you to rest between observations and fully enjoy the educational experience on offer.
A Mediterranean richness of flora and fauna
The marine nature reserve is home to more than 1,200 animal species and nearly 500 plant species, according to the Pyrénées-Orientales Department. Algae make up the largest share, followed by the many fish species typical of the Catalan coast. Along the trail, you may encounter shoals of salema fish, octopuses hiding in rocky crevices, red starfish, or occasionally a stingray. The Posidonia seagrass meadow, a true nursery for marine life, is one of the highlights of the route. Our team’s favourite spot at Camping Sunêlia Les Pins: The Posidonia meadow station remains our favourite stop. This underwater meadow acts as a true “lung” of the Mediterranean and hosts remarkably rich biodiversity. In practice, it is also where you are most likely to regularly see shoals of salema fish, sometimes accompanied by a few octopuses well camouflaged among the nearby rocks.
How to prepare for your visit to the underwater trail?
Good preparation makes the experience both more enjoyable and safer. The trail is accessible to swimmers of all levels, but a few precautions are necessary before getting in the water. Here are our practical tips so you don’t forget anything on the day.
Essential equipment for snorkelling
To fully enjoy the experience, bring fins, a mask, and a snorkel, as well as a short wetsuit for thermal comfort. If you don’t have your own gear, a rental point is available directly at Peyrefite Beach. You can also choose an FM snorkel, which provides audio commentary at each observation station. This educational option greatly enhances the visit, especially for children. Our team also recommends bringing a towel, a UV-protective T-shirt, and eco-friendly sunscreen for when you return to shore. “At Camping Sunêlia Les Pins, we always advise our guests to rent the FM snorkel for their first visit: the audio commentary turns the experience into a real marine ecology lesson, and children absolutely love it,” our reception team explains.
Safety rules to follow in the reserve
Before going for a swim, check the beach safety flag displayed on the shore: it provides information about sea conditions and safety levels. Stay at the surface, breathe calmly, and use the buoys if you feel tired. Freediving and spearfishing are strictly prohibited within the marine nature reserve. Do not touch fish or organisms attached to the rocks, and observe the seagrass meadow without stepping on it. These simple actions help preserve a fragile ecosystem and ensure a safe and peaceful visit for everyone.
