Sentier sous-marin de la Palud, Parc national de Port-Cros · 프랑스 프로방스 이에르(포르크로섬)
Location
Overview
Set in the bay off La Palud beach on Port-Cros island, this self-guided underwater trail sits inside the first marine national park in Europe (established 1963) and is one of France's original snorkel routes. Six large yellow buoys, each with a submerged interpretive panel, form a loop of roughly 40 minutes that you follow with just fins, mask and snorkel. The water is shallow — around 2 to 4 metres — with summer visibility of 10 to 20 metres, making it ideal for families and first-timers. Over the protected posidonia seagrass you'll spot wrasses, scorpionfish, sea urchins and pen shells, plus the park's two stars: the dusky grouper (mérou) and the brown meagre (corb). As of 2026 it remains free and open through the summer season.

Good to know
SafetyThere is no lifeguard on this open-bay route. Always snorkel with a buddy and carry a float or surface buoy — being a beginner-friendly trail does not make it hands-off.
SafetyThe mistral (strong NW wind) tends to build the swell in the afternoon. Swimming is discouraged on windy days; it's easy to be pushed toward open water or to tire, so judge conditions before you go in.
SafetyScorpionfish (rascasse) carry venomous spines and sea-urchin spines hurt if you kneel on them. Don't grab or stand on the rocks, and since Pelagia jellyfish appear in season, a thin shorty wetsuit helps guard against stings and stony scrapes.
RulesThis is a marine protected area: no collecting, fishing or anchoring, and no touching or standing on marine life or the posidonia meadow. Stay on the marked buoy route and use reef-safe sunscreen.
MannersNever feed or chase the grouper, corb or other wildlife — keep your distance. Don't stand on the seagrass or rocks, and control your fins so you don't stir up the bottom.
SeasonBest from June to September (roughly 15 June–15 September opening), with summer water at 22–25°C. July and August are busy — mid-week is often the most crowded, so weekends can be quieter. Come prepared for jellyfish and strong sun.
CautionWatch for unlicensed guides or overpriced gear rental. Book any guided snorkel (randonnée palmée) or equipment through operators recognised by the national park, and confirm current prices on site.
Practical info
Take a ferry from Hyères (Port d'Hyères / La Tour Fondue) or Le Lavandou to Port-Cros village, then walk about 30–40 minutes to La Palud beach and enter from the shore. The trail itself is free and self-guided, open in the summer season (roughly June–September). Ferry timetables and fares, guided-tour options and gear rental change seasonally, so confirm the latest details with the national park and ferry operators before you go.
