I won't repeat what the other reviews have said but I am quite a seasoned world traveller and this is a really unique experience. Also, they will most likely close this off to the public one of these days soon so don't miss your chance.

If you want to experience true adventure you must see the ATM cave in Cayo, Belize. My husband and I first visited the cave in 2005, was stuck in the jungle overnight with Carlos Panti, our guide and other tourist, had an amazing time. We became great friends with Carlos and have returned many times with friends to see the... More

We hesitated a bit, since everyone seemed to be doing it, and we like to avoid really touristy stuff. But, I'm so glad that we did it! The ATM cave was one of our favorite tours ever. It's a nice level of adventure (exciting, but not terrifying, as long as you aren't afraid of small spaces). Just be aware that... More

Not for people who can not be in tight spaces, are afraid of heights or is frightened by darkness. All others will think this tour ROCKS!

WHAT AN OUTSTANDING way to spend my birthday, a full DAY trip to the mainland to explore this incredibly, spectacular, elusive, historic, spiritual place. We flew the first tropic air flight from SPR, to Belize City Municipal airport from San Pedro. Our driver met us for the 70 min road journey to Tea Kettle, Belize- just West of Belmopan, Belize's...

We have been lucky enough to experience some pretty amazing sites around the world but none as thrilling at Actun Tunichil Muknal (or ATM). The drive was an hour or so from San Ignacio, the trek in from where we parked was probably another 20 minutes over a few rocky bedded rivers. The cave entrance is beautiful & we swam... More

I won't go into detail on the trip itself as there are many other reviews that do. We did our tour with Cayo Adventure Tours, tour guide was Martin. I highly recommend them and especially Martin for this trip. Martin is a very knowledgeable naturalist, and the experience was out of this world with him. Close to the beginning of... More

If you are in good physical shape, I highly recommend exploring the ATM cave. Nice cave formations, well-preserved Mayan pottery and skeletons of human sacrifices / victims, and an overall great adventure. As others have described, it is a 45 minute walk to the mouth of the cave. You cross a fairly slow moving river 3 times; 1 ankle deep,... More

I really enjoyed the ATM cave. I am a Belizean and I enjoy touring my country and I can say without a doubt that this was my best tour ever. Our tour guide, Patrick Bradley, was the best. It was evident that he had done this tour so many times because damn, he was good. There were only two of... More
