Tunnel

This dive site features a stunning underwater tunnel cutting through a limestone island, with sunlight streaming through openings in the rock. Schools of batfish and trevally often gather at the entrance. The tunnel leads to a vibrant coral garden teeming with anthias, butterflyfish, and occasional reef sharks. Depth ranges from 5 to 30 meters, with mild currents. The exit opens to a dramatic drop-off covered in soft corals and sea fans. Visibility is typically excellent, making it ideal for photography. The site offers both sheltered conditions and exciting drift diving opportunities.
