Dos Ojos Cenote Park — Private Tour

Dos Ojos is the front door to one of the longest underwater cave systems in the world. Divers go deep into it; snorkellers stay in the two connected cenotes that give it its name, which is more than enough — the visibility is the reason people come.

Nicte-Ha is the shallow, lily-covered one and the best for anyone nervous in water. Jaguar is the quietest of the three and usually the emptiest.

The park also runs a zip-line, which is genuinely a park attraction rather than a nature one — fine with children, skippable otherwise. Going privately means you can decide.
