Build each day around wind direction and surface state. North and west exposures can change quickly, especially outside the calmest summer periods. Use proper entry and exit timing on ladder and rock sites, carry an SMB, and respect boat lanes in lagoons and harbors. Do not treat cave mouths, tunnels, or historic wrecks as casual recreational extras. If you are going beyond standard recreational profiles, book operators who are set up for those objectives and confirm gas, access, and emergency procedures in advance.

Malta has established diving-medicine support. Mater Dei Hospital on Malta has a hyperbaric unit that provides recompression treatment, and Gozo General Hospital added a new six-person hyperbaric unit in March 2026 to improve emergency capacity for divers. That does not remove the need for insurance. Carry dive-specific cover that includes chamber treatment, evacuation, trip interruption, and any technical-depth rider you may need.

Malta's marine Natura 2000 network covers 18 sites and more than 35 percent of the country's Fisheries Management Zone. In practical trip terms, that means divers and snorkelers should treat Posidonia seagrass, cave systems, and sensitive reef structure carefully. Maintain neutral buoyancy, avoid kneeling on rock or seagrass, keep anchors off protected habitat, and never remove artifacts or marine life. Blue Lagoon visitor controls and Heritage Malta wreck rules are part of the same wider conservation and heritage-protection logic.
