Located in the beautiful Mountain Pine Ridge Forest Reserve, Rio Frio Cave is by far the most easily accessible of Belize's river caves. Everything is big in this cave! The two 65-foot arched entryways leave you in awe. Huge stalactites hang from the massive cathedral-like vault, which is part of a cave system the Maya used to bury their dead. Room size boulders are strewn throughout the cave and a stream flows through, forming pools with cascading falls. Openings at both ends make flashlights unnecessary for viewing the cave's formations during daylight hours.

There is a beach area with a foot bridge for crossing the stream and getting to the other side, which leads to the exit opening. It is a quarter mile through to the other side, another equally impressive opening. (Do bring a flashlight to watch your footing as you walk through to the other end and to explore other caves in the area). Laughing Jaw and several other caves are also located nearby. The trails are marked; and you can explore them on your own, or with your guide.
