Crystal Cave is one of the most exhilarating caves in the region. The initial climb through lush rainforest is steep and heart pumping. After a 60-minute hike, you arrive at the entrance of the cave; here, the real fun begins. You will descend up to 600 feet (183 meters) into a stunning cave system. Pick your way along sheer rock faces and slide down mud ramps. Littered with crystal stalagmite and stalactite formations, the chamber called the “cathedral” is mind-blowing. If you are up for this physically demanding excursion, it will be a high point of your caving experiences in the Cayo district.
