Chun Zumbul - Cozumel

Just a quick two-minute boat ride from Papatura, Grandma’s Garden is a cheerful bommie that’s shallow enough for snorkelers and divers alike. It starts at a comfortable three meters, dropping to a maximum of 19 meters, with average visibility sitting around 12 meters. We usually find the bi-directional currents here gentle, largely dictated by the tides, and it’s well-sheltered from the wind. The star attraction is definitely the fan corals, some stretching three meters wide, adding splashes of colour across the bommie. While it's home to plenty of smaller reef fish closer to the surface, keep an eye on the deeper sections for cruising trevally and giant trevally. It’s a pleasant, relaxed dive, perfect for an easy afternoon.
