ATM Cave Tour Highlights
The 45-minute flat terrain hike includes three river crossings. The first is shoulder deep with a rope as a guide and the other two crossings are only knee-deep.
Exploring the cave includes climbing on boulders, crawling, and squeezing through tight places. The rock formations called stalactites are stunning.
Known to the Mayas as the underworld, the cave was a sacfificial site where sacrificial ceremonies were performed. The remains are skeletons & pottery.
Should You Do The ATM Cave Tour?
My answer is a resounding yes. If you're not a swimmer, claustrophobic or scared or spiders, I think you should still do this tour.
Why? Because it's a once in a lifetime experience that will help you conquer all those fears. You also have access to a life jacket and a highly-qualified guide that has been doing this for 10+ years, so there is no excuse.
Well, technically there are some caveats. Tour companies don't recommend pregnant women, people with heart conditions, walking disabilities and those with back problems to do the tour.
But if you don't fall into any of those categories, you're all clear for a world-class spelunking adventure.
ATM Cave Tour Review (From A Traveler)
In case you're feeling uncertain or unsure whether to do this tour, this short review perfectly summarizes the tour experience giving you a good idea of what to expect.
We survived Actun Tunichil Muknal cave. It was the most challenging and adventurous thing I have ever done! I’m claustrophobic, afraid of heights and clumsy as hell. But our guide was so careful and amazing that I climbed around like a spider monkey and came out unscathed. I’m not the most physically fit - I drink, I sometimes like to smoke and if you find me running it’s because I’m being chased, but still I made it! It’s about 1.5-mile walk to the cave, crossing the river three times and a short swim into the cave. It was absolutely beautiful inside with crystal clear water, shimmering stalactites and formations, Mayan pottery and sacrificial remains. The history we learned was just incredible. You are in the water most of the time except for where the remains are located, and we were inside the cave about three hours. This is an absolute must-do if you come to the Cayo area! I cannot recommend it enough. You need closed toed shoes with a decent grip. I purchased keen closed toed sandals, and they were perfect. My husband and 18 year old son wore Merrell water shoes. Also wear cushy socks for when you climb up to see the artifacts.
