    StandoutExceptional marine biodiversity

    Little Brother Cenote, a smaller cousin to its more famous neighbors, offers a delightful cavern dive, particularly if you're looking for something a bit less intense than a full cave penetration. The entrance is shallow, leading into a well-decorated space filled with stalactites that hang like ancient chandeliers. We especially love the air dome; it’s a neat spot to surface and take a breath, feeling the cool air against your face before dropping back down. Visibility here is usually excellent, around 33 meters, making for comfortable viewing of the interesting invertebrates clinging to the rocks – keep an eye out for the Serpent Brittle Star. At a max depth of 13 meters, it’s a relaxed dive, good for newer cavern divers or those just wanting a chill afternoon in Cozumel's interior.

    Safety Notes

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