    Punta Sur. Oh, Punta Sur. This site is everything we love about Cozumel drift diving, dialled up. It’s a proper deep dive, so bring your advanced cert and good air consumption. The current here can be a serious ride, which means you just fly along, watching the reef unfold. You’ll spot schools of Cardinal Soldierfish hanging in the overhangs, sometimes so thick they look like a shimmering wall. We’ve seen Marbled Morays peeking from every crevice, and the Harlequin Bass are just everywhere, adding splashes of colour against the deeper blues. The real magic happens when you get to the Devil’s Throat. This is our favourite part. It’s a swim-through that drops you into a vast cathedral-like chamber, shafts of light piercing the gloom. The scale of it is incredible, like diving inside a giant's dream. You emerge onto the deep wall, and that’s where you have a shot at some bigger pelagics passing through, though often we’re just mesmerized by the sheer drop-off. Keep an eye out for Cherub Pygmy Angelfish here, they’re tiny but brilliant. This is a dive for those who love depth, current, and genuinely dramatic topography. It’s not for the faint of heart, but boy, is it rewarding.
