    StandoutExceptional marine biodiversity

    Baie Ternay is our kind of protected reef: busy but not overhyped, and with enough going on to make a few dives here worthwhile. It’s an easy 20-minute boat ride from Beau Vallon, and the maximum depth here is 20 metres, so it’s a relaxed drift for most divers. We love dropping in when a light current is running; it really brings the reef to life, pushing schools of fusiliers into dense, shimmering walls. The coral gardens, particularly the staghorn formations, are a big draw. Look closely, and you’ll spot all kinds of wrasse darting between the branches – the six-line and dotted wrasse are common here, along with the occasional golden trevally cruising by. Our favourite moments here involve just hanging out on the sand patches, watching the blennies peek out from their holes and catching a glimpse of a broom filefish. Visibility averages about 13 metres, which is decent enough for spotting the resident hawksbill turtles or a white-tip reef shark gliding past the reef edge. It’s a great spot for newer divers to experience a healthy reef without deep dives, and for photographers to really focus on macro life and smaller reef fish.
