Mare

Scuba: No named operational Mare shop, diving conditions, compressor, oxygen station, dive-boat rescue plan, certified guides, deco management or local chamber was verified. Do not plan unsupervised scuba, technical or overhead diving, or treat sightseeing caves and sinkholes as dive locations. A future commercial scuba offering must independently confirm permits, qualifications, medical fitness, gear/gas quality, oxygen, evacuation, daily conditions and specialist insurance.

Freediving: No local professional depth program was verified. Do not turn a snorkeling cove into a solo depth session or infer safe depths. Use qualified supervision and a fully competent safety buddy for any separately arranged apnea diving. Never breath-hold in caves or the Natural Aquarium.

Snorkeling: Verify current community access, ask a knowledgeable local about entry/exit and conditions, stay in sight of a capable buddy, avoid murky water after rain and cliff/surge zones, and do not touch coral. A territory-wide shark-safety guide gives avoidance advice; it does not establish a specific Mare species, sighting guarantee or a lifeguarded beach.

A La Roche medical center is listed for Mare with telephone +687 45 41 01 and weekday consultation hours, but the directory is not proof of a 24-hour staffed emergency department. A July 2026 report described shortages of Mare physicians and difficulties accessing health care; restoration as of early November was not independently confirmed. Call 15 for medical emergencies, and 16 for sea rescue. The CHT Gaston-Bourret referral hospital is in Greater Noumea, not on Mare: hospital contacts. A hyperbaric treatment facility is listed at CHT by a professional directory, but current chamber operations, treatment availability and transport time have not been verified for this trip: chamber reference. Because flight access remains disrupted and ferry availability requires confirmation, travelers needing time-critical care should not assume a particular evacuation time. Confirm insurance covering medical transfer and contact local emergency authorities directly for operational decisions.

Mare coastal access is inseparable from customary stewardship. The island's official visitor map calls for permission before visiting or photographing tribes and certain sites, and says chieftaincy grounds must not be entered or photographed. Beach access may be temporarily closed under customary restrictions; obey markers and local instructions. Never chase or feed marine animals, stand on coral, remove shells or wildlife, anchor on coral, or disturb fishing gear. The Natural Aquarium is a fish/turtle observation basin with no swimming allowed, not a conservation-approved swim-with-turtles site. Tourism descriptions of fish, turtles and reefs do not establish guaranteed wildlife encounters at a particular beach. No reliable Mare-specific marine-park tag or reef-rule inventory was verified, so site-specific restrictions remain to be checked rather than invented.
