Amazing! I was a little nervous at first about the tight spaces and cold water but didn’t have any problems at all. You can’t go to Belize without seeing the ATM caves! Only bummer is you can’t take pictures but I totally understand the reasoning.

We used M&S Adventures out of San Ignacio. Our guide Renan is an original guide back to when the cave was first opened and his context, passion and knowledge of the history and culture of the Maya people is so moving. The tour was so amazing. We are mid-50’s and not necessarily in tip top shape- and while there were a few moments of pause (I don’t like heights) we managed quite well! I wore leggings and a tankini top which felt like the perfect combo for a day of being wet. Socks with water shoes are also key. Tip your guides! They work hard!

I visited the ATM cave in Belize in March 2000. Program didn’t allow date so far back. It was shortly after cave was opened to tourists. It was certainly not what I expected on an unknown, at the time, place to spend a relaxed vacation day. It wasn’t relaxed by any standard, but turned out to be one of the most exciting, adventurous days I could have imagined. Had no idea what the day was presenting me. I expected a short hike into a local cave. Instead, I ended up wading, swimming, climbing into an enchanted world of the past where artifacts, cave structures and skeletons were bountiful. Truly a wonderful, once in a lifetime, experience.

Our visit was AMAZING. We couldn't believe how close you get to the artifacts, the cave is beautiful and very atmospheric, it didn't feel crowded (I think we were one of the earlier groups to go in), and our guide Basilio kept us safe and taught us lots about the cave and the Mayans who used it. It really was a once in a lifetime experience. A truly fascinating place. Regarding fitness levels, my husband and I walk 2-3 miles (on pavement) after work most days and are both a little overweight, and neither of us struggled. As for old injuries, I fractured my wrist (radial styloid, with associated soft tissue damage) about 10 months before we went and I was fine wearing just a light wrist support. For anyone worried about creepy crawlies, I only saw one scorpion spider (from quite far away).

Totally unique caving experience. There is a 45 minute walk/hike to the cave—each mile way, but it’s worth it. They, supposedly, only let in 175 people a day. The pottery, skeletal remains, formations, and adventure were fantastic. It is a long day.

Actun Tunichil Muknal is amazing on many levels. Fording a river three times to reach its entrance and then swimming into a cave that gets increasingly dark is an experience beyond the everyday. My husband and I toured with Mayawalks and were lucky to have Hugh as our guide. Hugh is a font of knowledge about Mayan culture in general and about ATM in particular. My husband and I are on the older side (79 and 77) for adventures such as this one but we have remained active as we aged and were able to negotiate the water, the tight squeezes and the slippery rocks just fine with Hugh as our guide. The history of the cave with its human sacrifices was compelling. As a long drought set in, Mayans in the area tried to appease the rain god with various sacrifices with the final sacrifices being human. Hugh explained all of this in great detail. I highly recommend Mayawalks and consider yourself lucky if you get Hugh as your guide.

THE MOST AMAZING EXPERIENCE! Truly, one of the highlights of our week in Belize. It was like 2 adventures in 1—physically scaling the cave was really fun (plus the three river crossings), but culturally and historically was a whole different experience. We learned SO much, had a blast, and all thought it was just incredible.

We did this tour in March 2024 with 2 adults and 2 kids aged 9&11. This was probably one of the single greatest things I have ever done on any trip, and I am fortunate to have travelled to many places. First off...if you do not go with River Rat and have Gonzo as your guide then you are not getting the experience that you deserve. He was above and beyond in every way. His knowledge is bar none when it comes to this cave and the history as well he knows the cave like the back of his hand.....so you may get to go in some areas that others don't know about. Just do yourself a favor and book with Gonzo at River Rat, you wont regret it. From the moment you start the hike the adventure begins. You are in rivers, swimming, rock climbing, spelunking....its the greatest adventure with the most beautiful reward of being able to see the relics left behind and having the privilege of being in the space of the Mayans. This is a must do for adventure seekers. I would recommend having some level of fitness and there is a lot of climbing and some swimming.

This is a great experience. You will get wet and need to cross some very narrow (albeit short) passages but it is very worthwhile. Unfortunately you cannot bring along a camera or phone...Too many relicts were broken by tourists dropping them etc. I absolutely recommend it
