Boat-accessed cavern dive inside a mountain with an open roof.
Boat-accessed cavern dive inside a mountain with an open roof.
Hole of Ha is a roofless cavern dive inside a mountain in Corfu, where the practical approach is a short transfer from the diving center and the whole experience is built around the open ceiling, sunlight, and the feeling of being inside the rock. The chamber is shallow enough to feel comfortable but still demands cavern discipline, careful buoyancy, and a conservative turn if you want to stay within the lit, open portion of the site.
Conservative baseline from public research. No community dives logged yet.
