Just because they were expecting, did not mean Kay and Eijiro were going to sit still on their Mexican babymoon!

Locate about 60 miles south of Cancun in the Riviera Maya, Aktun Chen offers an adventurous and up-close interaction with nature. A zipline flight through the jungle canopy was obviously out of the question for mommy-to-be, so instead they opted for a cave tour and a snorkel trip.

The guided tours take you through a 600 meter long dry cave. You’re provided with helmets and the caves are well-lit with easy-to-walk paths. The cave itself is more than 5 million years old, with stalactites and stalagmites on display.

Kay and Eijiro also took a snorkel tour though the park’s cenote – or underwater cave.

Again, the equipment was provided. Each snorkeler gets a floatation belt, mask and snorkel. You can glide through the warm, crystal clear water to check out the rock formations.

An Aktun Chen trip is quite affordable as well. This two-tour package will run you US$45 each for three hours of guided adventure. Kay wisely recommends seeing out the “locals” parking lot near the caves. Parking in the bigger “tourist” lot is a total rip-off. Great tip!
