    StandoutExceptional marine biodiversity

    Chun Zumbul is a solid choice for a relaxed dive in Cozumel, especially if you’re not keen on long boat rides. This shallow reef, topping out at around 11 meters, is a really comfortable spot to explore. We’ve often seen gardens of brown garden eels swaying in the sand, alongside some surprisingly large tarpon cruising by. It’s perfect for newer divers getting their fins wet, or for experienced eyes who enjoy really taking their time to spot things like pygmy morays tucked into the coral. Visibility averages 17 meters, which is usually plenty good for enjoying the corals and sponges.

    Safety Notes

    Strong currents typical this month (avg 79 cm/s). Good buoyancy control essential.
