Key Dive Site Facts
Dive Site Overview
Seal Cave's geological narrative is etched into its impressive formations, drawing divers into ancient underwater landscapes. Historically, its name derives from occasional sightings of the Mediterranean monk seal, or "Fokia," a shy inhabitant that once frequented such marine shelters.
Divers entering the site discover expansive caverns and intricate ravines. One notable feature, depending on the specific location, includes a main chamber sizable enough to allow dive boats to partially enter. Inside, natural light rays penetrate the water, creating a dynamic visual experience against the rock walls.
These spaces often present a flat sloping landscape, characterized by sandy bottoms meeting dramatic rock formations. Some sections might also reveal a halocline effect where fresh spring water mixes with saltwater, especially in areas with terrestrial water sources.
Exploring deeper, divers encounter impressive stalactites and stalagmites, evidence of millennia of geological activity. A ceiling in some cavern entrances lies nearly 2 meters (6.5 ft) above the water surface, offering an opportunity to surface within the cave itself.
This blend of open, light-filled spaces and more intimate passages defines the site's unique character.

Dive Experience & Conditions
Exploring the depth profile of Seal Cave offers a gradual descent into its various chambers and passages. Divers typically start in shallower sections before reaching its maximum depth, generally 21-25 meters (70-80 feet). The site consistently offers excellent visibility, often extending beyond 20 meters. Conditions inside the caverns are typically calm, with limited or negligible currents reported, making navigation straightforward.

Some areas may present a halocline, where freshwater mixes with the sea, adding a distinct visual layer to the dive.
Dive Difficulty & Safety Guidelines
An expert tip for diving Seal Cave emphasizes the importance of buoyancy control and awareness within confined overhead environments. While the site is accessible to Open Water certified divers and those new to cavern diving, maintaining precise control is crucial to avoid disturbing the delicate formations and sandy bottoms. Always dive with an experienced guide, especially given its isolated nature where immediate assistance might be distant. The cave's main entrance allows some light penetration, yet divers should carry redundant light sources for exploring deeper, darker sections or smaller passages. Due to boat-only access, careful entry and exit procedures are essential. Comprehensive pre-dive briefings are mandatory to understand the specific layout of the cavern, potential haloclines, and any variations in conditions. Dive planning should account for small group sizes to enhance safety and ensure a tailored experience for all participants.
