Status: Open
Visibility: good (30–60+ m / 100–200+ ft)Default estimate: inside the caves the visibility is 30–60+ m all year. The water is filtered through tens of metres of limestone, so rain hardly clouds it inside. Divers' reports come first. Source: Aqua Core Adventures ↗

The dive

Usil lies semi-closed in a grotto: a blue water surface of only 20 by 6 m, with a shaft of some 112 m below it. The villagers tell of a guardian in the depths.

Shaft of about -112 m under a small water surface; nothing published about lines or the bottom. Technical dive only, with a guide who knows the cenote.

It is the main cenote of Cenotillo, 'the town of cenotes', and after Sabak Ha the deepest known cenote in the state. What lies underwater in lines or passages is not published.

How to get there

2 km outside Cenotillo on the Buctzotz–Tizimín road, about 100 km north-east of Mérida. A side entrance into a grotto, then stairs to the water; the slope is slippery. Go with someone from the village; ask about the fee.
