    StandoutExceptional marine biodiversity

    Drop in, and you’re instantly pulled into the Santa Rosa flow. This isn't just a wall; it's a vertical city, falling from 15 metres and just keeps going. We love the feeling of hanging over that deep blue, watching schools of horse-eye jacks wheeling in the distance. Keep a close eye on your depth gauge here, it’s easy to get distracted and go deeper than you intended, the wall just beckons you down. The current often dictates your pace, but we always try to slow down at the overhangs and the bigger swim-throughs. The light rays piercing through the cuts in the coral make for incredible photo ops, and you’ll often find nurse sharks resting in the shadows. Look for the Splendid toadfish, Cozumel’s own, tucked into crevices – their vibrant yellow faces are hard to miss once you know what you’re looking for. Spotted eagle rays often glide by in the deeper sections, so always keep an eye out into the blue. This site suits divers who are comfortable with drift diving and managing their depth, and who appreciate a grand, dramatic underwater landscape.
