Santa Rosa Shallows - Cozumel

We’re always a bit wary of newly discovered sites, but Terno quickly became one of our favourites in Salvador. This isn't just a small patch of coral; it’s an expansive reef system that just keeps giving. Drop down, and you’ll find yourself gliding over a rolling landscape of hard corals. We’ve had dives here where the schools of grunts and snappers were so thick it felt like swimming through a silver cloud. Look closely, and the reef reveals its smaller residents: we’ve often spotted ornate orangespotted filefish picking their way across the corals and the occasional reef scorpionfish perfectly camouflaged on a bommie. The Terno is a shallow dive, maxing out at 12 metres, which means plenty of bottom time and lots of light playing on the reef. Visibility averages around 10 metres, sometimes a bit more, sometimes a bit less, but usually clear enough to appreciate the scale of the site. It’s ideal for less experienced divers looking for a relaxed exploration, or for photographers wanting to spend time with the smaller creatures without deep-dive constraints. Keep an eye out for green sea turtles munching on algae, and we’ve regularly encountered morays peeking from their rocky hideouts. This is a site to take your time and simply soak it all in.
