Safety · Destination Guide
Volcanic reef diving, serious apnea and carefully regulated lagoons on Reunion's west coast.
This is a regulated marine-reserve and shark-risk coastline. Never select a beach or dive site using old photos alone: the 2026 prefectural coastal order, the reserve's sanctuary zoning, active municipal signs and current lifeguard flags all matter. Most scuba is operator-led from boats. For an emergency at sea contact CROSS on 196 or VHF 16; medical emergency service is 15 or 112. The CHU hyperbaric service is located at Saint-Pierre, not inside this limited west-coast guide region.
The CHU La Reunion hyperbaric medicine service is based at CHU Sud in Saint-Pierre and handles suspected diving decompression illness through emergency referral; its secretary contact is not a 24-hour dive-emergency line. On a suspected diving accident, end the dive, give emergency oxygen if trained and supplied, summon professional emergency assistance, and follow local emergency coordination. At sea use 196 / VHF 16 for CROSS and 15 / 112 for medical emergencies. Confirm provider oxygen and evacuation logistics before boarding. Consider personal medical and hyperbaric/repatriation insurance: general travel insurance may exclude scuba depths, freediving, technical profiles or evacuation. In case of any decompression symptoms, do not fly or drive uphill.
Shark risk and changing bathing permissions
Observe the current 2026 prefectural order, municipal rules and live flags. The absence of a specific PMT ban in this version is not a general declaration of safety or unconditional permission. Shark risk persists outside protected swimming areas.
Open lagoon passes can pull strongly
The Hermitage pass notice warns about current. Never cross reef passes, chase wildlife offshore or swim near active channels.
Fully protected sanctuaries are no-entry underwater zones
No recreational scuba, apnea or snorkel in the reserve's zones de protection integrale (ZPI). The reserve rules apply regardless of how calm the water appears.
Sea state and cyclone disruption
Wind shifts, heavy rain, swell and port closures can alter all boat departures. The meteorological authority identifies January-March as the rainier core, but warnings can matter outside these months.
The west-coast reserve protects coral habitats and fauna and sets zones de protection integrale that bar scuba, apnea and underwater trails. Operators and associations need activity authorization, renewal and reporting; boats should use permitted moorings rather than anchoring on reef. Do not touch or feed wildlife, collect shells or coral, stand on living substrate, or pursue turtles. Reserve conduct and permits. The Kelonia conservation center illustrates turtle rehabilitation. The 2026 cetacean rules constrain approaches to protect mothers, calves and other cetaceans: no normal dive or casual snorkel confers whale-approach rights.
Do Not Do This
Avoid entering when shark risk and changing bathing permissions. Confirm local briefings before committing.
