Aktun Chen Natural Park

Aktun Chen Natural Park is about 4 km (2.5 mi.) s. of Akumal (watch for the signed turn-off on the right side of Mex. 307 going southbound), then another 4 km (2.5 mi.) down a narrow dirt road to the entrance. This nature park offers a guided half-mile walking tour through a dry cave festooned with stalactites, stalagmites and other natural limestone formations, all enhanced by indirect artificial lighting as well as natural light coming through openings in the cave ceiling.

The tour ends at a freshwater underground cenote with green-hued water that is mostly shallow but reaches a depth of 10 feet in parts. The water is not only remarkably clear but illuminated, creating ideal snorkeling conditions. There is an extra fee to snorkel in the cenote.

For daredevils there's the “Canopy” zipline tour that also features two suspended bridges. Animal exhibits include deer, spider monkeys, toucans, parrots and snakes; wild turkeys and iguanas freely roam the park grounds.

On-site parking is available; for visitors arriving by taxi or colectivo a free shuttle service travels to and from the highway entrance and the park reception area. Restrooms are available. Activity equipment and lockers are provided. Wear comfortable clothing and footwear and bring a bathing suit, towels, biodegradable sunscreen and mosquito repellent.

Food is available. Time: Allow 3 hours minimum.
