House Reef

House Reef is the main house reef dive near Santorini in the Cyclades, offering easy access to a volcanic underwater landscape unique in the Mediterranean. The reef features dark volcanic rock formations interspersed with lighter sand, creating a striking visual contrast. Santorini's volcanic geology means the reef substrate is different from anywhere else in Greece, supporting unique encrusting organisms adapted to the mineral-rich rock. Marine life includes colourful wrasse, damselfish, octopus, and moray eels. The famous Santorini visibility — often exceeding 30 meters — makes every dive here feel extraordinary. Perfect for multiple daily dives and suitable for all experience levels from discovery to advanced.
