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.
