This archaeological site is about one hour from San Ignacio and requires about four hours from beginning to end. The drive to the cave is very scenic, passing through a few Maya Villages along the way. It is only accessible by canoe and requires minimal physical activity as you glide along gently. Formations of stalactites and stalagmites found inside are remarkable. Evidence of use by the Maya exists on ten ledges within the first kilometer of passage. Pottery shards indicate use between the Early Classic (200 to 600 AD) to the Late Classic (600 to 900 AD) periods. The remains of at least 28 humans have been found within the cave. This tour is slow paced, educational, and fun for all ages.
