Yanbu Reefs

Before each dive, verify cylinder gas, buddy roles, surface signaling, boat recall method, the skipper's weather assessment and coast-guard/Border Guard clearance. Use a certification-appropriate profile; some Seven Sisters offerings explicitly require Advanced Open Water, while a published seven-night voyage specifies Open Water with a minimum of ten logged dives plus advanced-current experience recommended. Wreck penetration, cavern and technical diving require separate evidence and credentials; do not enter Iona or any overhang because of a marketing photo. Snorkelers should have their own guide and approved shallow-water plan. Freedivers need one-to-one buddy coverage as applicable, an instructor and an oxygen/rescue plan, never solo depth sessions. The DAN flying-after-diving advice specifies at least 12 hours after a single no-stop dive, 18 hours after multiple no-stop dives and a substantially longer interval after mandatory deco.

The Royal Commission medical network lists a Yanbu Medical Center, and Mouwasat describes a Yanbu hospital with emergency services. Neither citation independently verifies a chamber capable of recompressing injured divers or its operating schedule. PADI's general Yanbu entry names Jeddah as a chamber location, but that community-contributed entry is not confirmation of an operational or publicly available service. Before a remote reef day, require the operator's current written plan identifying oxygen, extraction vessel, communications, receiving emergency department and how doctors arrange treatment or evacuation. For suspected decompression illness, call local emergency services, give first aid and emergency oxygen if trained, and seek DAN consultation; do not bypass an emergency department to chase an unconfirmed chamber.

Saudi National Center for Wildlife and Saudi Water Sports and Diving Federation guidance warns of habitat damage from anchoring on coral and seagrass. Choose operators that use lawful moorings or reef-safe anchoring, practice neutral buoyancy and avoid touching or standing on live coral. Never remove organisms or archaeological objects, feed sharks or fish, chase turtles, or approach wildlife for a photograph. Reef protections, collection rules and site closures may vary; ask the licensed operator and relevant authority what applies on the exact route. Do not assume a particular Yanbu reef is a designated marine park solely because another Red Sea destination uses a permit tag.
