About Twin Tunnels Reef
A pinnacle reef that rises from deeper water to around 15 m below the surface. Two vertical shafts drop from the reef top to a chamber, with a cave exit around 36 m. Currents attract both predator and prey, and the site is described as healthy, colorful, and vibrant, with enough to warrant multiple dives.
