Asturias: Gijon / Cudillero / Costa Verde

Use conservative profiles and make the dive plan match the sea state. A DSMB is essential for boat diving and useful around any exposed site. Expect lower visibility after rain or swell, and do not enter caves, arches or overhangs without appropriate training and a guide. Spain requires recreational divers to have accident and civil liability insurance. Confirm oxygen, emergency plan and nearest chamber routing with your centre before diving.

For a serious incident, call 112 first. Gijon has hyperbaric medicine support at Ribera Covadonga Hospital, but divers should not self-diagnose or self-transport suspected decompression illness without emergency coordination. DAN Europe can support diving emergency advice and evacuation coordination for covered members. Carry travel insurance that covers scuba, cold-water boat activity and any mountain driving or hiking add-ons.

Stay neutrally buoyant over algae-covered rock, sponges and anemones. Do not collect shells, crustaceans or octopus, and avoid moving rocks for photos. Use reef-safe behavior even though these are not coral reefs: no gloves-on grabbing unless required for safety, no finning into the bottom, no harassment of conger, lobster or spider crab, and no drone or cliff disturbance near nesting birds in protected landscapes such as Cabo Penas.
