About Heybeliada
Heybeliada is a Marmara Sea dive area off Istanbul's Princes' Islands, where rocky reef sections, sandy slopes, and a deeper wall give the site a wider range than a simple beginner reef. It suits divers who want a classic island boat dive with strong visibility potential and enough structure for both easier and more advanced routes.

Boat traffic
Safety Notes
Treat the wall and technical section as separate from the beginner reef line, and keep a conservative plan around surface traffic and wake.
Access Restrictions
Plan the dive with an Istanbul-side or island-based boat operator. Heybeliada is ferry-reachable, but the dive itself is not a casual walk-in shore entry.
Legal Notes
Follow Turkish maritime rules, local club guidance, and any island access or conservation restrictions in force.
Local Intel For Heybeliada
Community notes to help plan your visit.
Scuba Diving
Boat-access Marmara site with a shallower reef for newer divers and a deeper wall for experienced teams.
Freediving
Only the calm, shallow reef edges are sensible for freediving; the wall and technical section are scuba terrain.
Snorkeling
Snorkeling is secondary here and only makes sense in the calmest shallow water close to the island.
