Turbo Tunnel is a rock canyon at Grande Island that divers swim through from end to end. Its steep sides are covered in orange sponge and whip corals, and the passage is at its most fun when a slight surge is running through the gap.

The dive
The dive is the canyon itself, swum at about 8 m between steep rock walls. Orange sponge and whip corals cover both sides of the passage, and a slight surge, when there is one, makes the swim through more fun.
