Everything you need to know about this dive site.
Dive Site Overview
Entering the natural archway of Galleria offers a journey into a remarkable subaquatic realm. After a short 15-minute boat ride, divers descend into a large initial chamber, often flooded with natural light, creating an amphitheater effect.
Fine sand characterizes the bottom here, where one might spot flounders or cuttlefish moving discreetly. Further exploration leads into a network of passages; some sections resemble a block of 'Swiss cheese' due to their numerous circular openings and pathways. These intricate swim-throughs are a highlight, leading through rocky arcades and small caves, sometimes culminating in air-filled chambers adorned with stalactites.
A varied and colorful underwater landscape ensures a dynamic dive. Especially engaging for Open Water divers comfortable with cavern environments, it offers substantial exploration without extreme depth.
Maximum depth within Galleria typically remains around 15 m / 49 ft, though some areas, especially near underwater landslide rubble, may extend to 22 m / 72 ft. Divers will find interesting plays of light and shadow, particularly near the 'windows' described in deeper cave sections, enhancing the overall exploratory feel and making each turn a new discovery.
A blend of reef and cavern structures provides a rich tapestry for underwater navigation and observation.

Visibility is consistently good, allowing divers to appreciate the intricate rock formations and diverse marine life within caverns and along the reef. Water temperatures vary depending on the season, commonly experienced within the Mediterranean range of 14-26°C (57-79°F). Its underwater landscape is varied and colorful, shifting from open, light-filled chambers to narrower, more complex passages. Divers will navigate around the rubble of ancient underwater landslides, which has created additional nooks and crannies to explore. Diving transitions under rocky arches adorned with sponges and false coral, where yellow Gorgonia can be found, providing excellent photographic opportunities and refuge for smaller fish.
Dive Difficulty & Safety Guidelines
Navigating the intricate passages of Galleria requires adherence to established safety protocols for cavern diving. Site access is available to certified Open Water Divers, but divers should be comfortable in overhead environments. Though the first chamber is often well-lit, exploring deeper sections mandates carrying both a primary and backup torch to penetrate darker areas and appreciate the full spectrum of light plays. A cavern line is not consistently present, emphasizing the importance of excellent buoyancy control and spatial awareness. Maximum penetration into the cavern is generally recommended at 60 meters (200 feet) from the surface, well within no-decompression limits for recreational divers. Diving here with a local professional guide is highly recommended, as their familiarity with the site's layout ensures a safe and enriching experience, particularly through the more labyrinthine sections.
