Traveler, Elizabeth Coughlan, shares some of her experiences exploring the Actun Tunichil Muknal (or ATM) cave in Belize. Learn a little about the logistics, the how-tos and what to expect. I can tell you from personal experience, you can prepare all you want for this tour, but there is no way to predict what the journey to this archaeological treasure will mean to you. I'll try and avoid sentimentality, but the ATM cave is exceptional and dramatic. It pulses with energy -- its intriguing history is easily rivaled by its surprising beauty. I had the privilege to explore ATM in 2005, and it is still stands out as one of the most memorable experiences I have ever encountered in my travels.
