Aktun-Chen

With forest canopy zip-lines, cenote-swimming, light caving, and wildlife-watching, this six-acre nature-based theme park set in scrubby jungle mixes safari park-zoo with light adventure in nature.

There are three separate tours which can be done independently or in combination: a zip-line circuit through the trees, snorkelling in a cenote, and/or a tour through a 5 million-year-old cave dripping with stalactites and stalagmites and coursed by a glass-clear underground river.

Facilities are simple – with little more than a Mexican restaurant – but there are far fewer tourist-bus crowds than at nearby Xel-Há.
