Punta Sur - Devil’s Throat - Cozumel

South Dolphin is one of our favourites in Watamu, especially if you’re looking for a relaxed dive with plenty to see without going too deep. The plateau itself starts around 12 metres, then gently slopes off to about 20. We usually descend on the buoy line, then drift along the edge, letting the gentle current guide us. What really sells South Dolphin for us is the coral coverage. It’s beautifully overgrown, a real mix of hard and soft corals that seem to just melt into each other. You get these lovely purple soft corals swaying with the surge, interspersed with brain corals and plate corals. It creates so many little nooks and crannies, perfect for spotting the smaller stuff. We’ve had some great encounters with scorpionfish here, perfectly camouflaged, and moray eels peeking out from every crevice. Schools of fusiliers often hang above the plateau, shimmering as they move. Keep an eye out for grey sweetlips too, sometimes huddled in small groups. Visibility averages around 14 metres, which is usually more than enough to appreciate the details. This site is ideal for those who prefer a less strenuous dive but still want a vibrant, healthy reef experience.
