Twin Tunnels Reef

★★★★☆ (25)

This pinnacle reef rises up from the the bottom at 70+ m to within 15m of the surface. Two vertical shafts descend from the reef top to a chamber and cave exit at 36m where both predator and prey congregate in the current. Healthy, colorful, and vibrant where a single dive hardly does it justice.

All varieties of soft and hard corals can be found here. Various species of anemone fish live side by side in the same anemone. Pelagics, rays, sharks and reef fish in abundance.
