Boat-loop tunnel dive in Sarigerme with a wall exit and mixed marine life.
Boat-loop tunnel dive in Sarigerme with a wall exit and mixed marine life.
Blue Tunnel Sarigerme is a boat dive built around a shallow overhead tunnel with two atrium-style chambers that opens onto an outer wall and returns in a loop back to the boat. It is one of the better-known Sarigerme dives because the route mixes the tunnel section with open-sea structure and the chance of surprise marine life. Divers should plan for guided boat logistics, controlled buoyancy through the overhead section, and day-by-day routing that depends on weather and sea state.

Late spring through early autumn is the easiest window, with warmer water and more stable conditions.
Typical Conditions
Open-sea conditions can vary and marine life sightings may be unpredictable.
Site conditions, restrictions, and access requirements.
Site Conditions
Safety Notes
Keep buoyancy tight through the overhead section and follow the guide closely on the circuit.
Access Restrictions
Boat access only; the overhead section makes it a guided site rather than a casual shore dive.
Legal Notes
Follow local operator briefings and any harbor or sea-state limits for the day.
Community notes to help plan your visit.
Scuba Diving
The tunnel leads into an outer wall circuit that finishes back at the boat, so buoyancy and route discipline matter more than depth.
Freediving
Possible only for confident freedivers who are comfortable with an overhead section and a guided loop; scuba is the easier fit.
Snorkeling
Not a full snorkel site. The tunnel and wall section are the real draw, so surface-only use is limited.
