We did this tour through Mayawalk in San Ignacio and I highly recommend them. It was truly an excellent day. Rio Frio Cave is a eco-tourist destination in Pine Ridge Forest Reserve, Cayo District, Belize. It's one of the stops that are made on the way back from Caracol. Caracol is a major Mayan archaeological site frequented by travelers in Belize. It's definitely a stop along the way that tops off a fantastic day.
