Baie Ternay Marine Park

Protected marine park reef, nothing deeper than 20 m

Baie Ternay is a protected reef inside a marine park on the north-west corner of Mahe, twenty minutes by boat from Beau Vallon and no deeper than 20 m. Hard and soft coral cover the bottom, octopus and hawksbill turtles work the reef itself, and barracuda, rays and white tip reef sharks show up along its edges.

The dive

Twenty minutes from Beau Vallon beach, or eighteen from Bel Ombre marina, the boat anchors on sand inside the area where anchoring is permitted, and the dive starts on a protected reef that bottoms out at 20 m. There is no reason to chase depth here: hard and soft coral run from the shallows down, and the reef is worked slowly rather than crossed.

Move slowly across the coral for octopus tucked into holes, stonefish sitting still on rock, and hawksbill turtles feeding. Parrotfish, pufferfish, cornetfish, trumpetfish and boxfish make up the everyday cast, and the edges of the reef are where rays, barracuda and the occasional white tip reef shark appear. Current is unpredictable, sometimes light and sometimes strong, so keep track of the boat throughout.

Season follows Seychelles: Inter-monsoon periods (Mar-May, Oct-Nov) are calmest with the best visibility; whale sharks pass through the inner-island channels August through October.

Know before you go

  • Current can switch from light to strong, and the boat sits at anchor rather than on a mooring, so plan the return leg before swimming away from it.
