It will take us an hour to drive to the parking lot. Your experienced guide leads your group on an easy 35-minute hike to the cave entrance. Walk along the bank of the Roaring River, which you’ll cross three times before arriving at the cave entrance. To prepare your group for entering the cave, your guide provides a historical overview and a safety briefing. The water passage allows you to splash and play as you wade through the water, which may come up to your ankles, knees, waist, and even neck—sometimes requiring you to swim. At one point, you’ll climb up to a ledge to enter one of the most attractive parts of the cave, where archeologists have recorded more than 1,000 pieces of pottery and 19 human sacrifices. To explore this chamber, you must remove your shoes to protect the natural surroundings, including impressive formations like rock columns, stalactites, stalagmites, citrines, and flowstones. Your guide will share fascinating details about ancient Mayan rituals and ceremonies that once occurred deep under the earth.

Amazing one of a kind experience. Highly highly recommend, excellent tour guide and lunch was delicious. Very adventurous, the cave was massive. You’ll drive to the location, leave everything in the car besides water bottles, put on equipment then cave exploring for a few hours. After the hike you get to change into dry clothes for the ride back. Our tour guide Francisco was more than amazing. Couldn’t ask for a better day

Pickup was on time and our guide Gliss was kind and very informative. He helped us along and explained so many things. The cave itself was really cool and learning about the Mayan culture was interesting. I wish we could take cameras or the guides could have taken pictures for us but cameras are banned. It did require a certain level of fitness so be Miguel of that since we were scrambling up and down rocks, swimming and crawling through tight crevices.

we were off to a bad start due to our driver being late by nearly 40 mins. I had already dropped the maximum rating I was going to give to 4 stars. Fortunately, that’s where the bad ends and the amazing begins. Our tour guide Fernando was extremely knowledgeable and humorous. With his expertise, we swam, climbed and explored the cave with our small group. It was truly an adventure that intrigued the archaeological side in me. The journey itself was a bit challenging but it’s manageable. At the end of it, exhausted and hungry we got to enjoy a delicious and tender meal that was much needed. Our whole group was satisfied and recommends the trip to anyone seeking adventure
