Rocky Amouliani islet with routes, walls, and fish life.
Dias is a boat-access rocky islet off Amouliani with alternative routes, boulder fields, and wall sections that let the same site feel very different depending on how deep you go. The site is known for rich marine life, constant exploration, and night-diving potential, with enough structure to reward careful buoyancy and a slow look around the rocks.
Site Conditions
Safety Notes
Pick the route that matches your certification, keep a close buddy plan on the deeper lines, and do not treat the shallow side as permission to wander the whole site.
Access Restrictions
Boat access only. The site is best reached through the local Amouliani and Ouranoupoli diving circuit, especially for the deeper or night-diving lines.
Legal Notes
Follow local diving rules and operator briefings; no special closure or restriction is indicated here.
Community notes to help plan your visit.
Scuba Diving
Good for certified divers who want route choice. The site can be a relaxed exploration or a deeper multilevel dive depending on the line chosen.
Freediving
Not a freedive-first spot. The deeper sections and wall features make scuba the better fit.
Snorkeling
Possible only in the shallowest calm-water sections, but the site is primarily a scuba destination.
