Let's DO this! >> Actun Tunichil Maknal Cave in Belize. It's a protected area, so you need to join a licensed tour to go there. Once in the rain forest, its a 45-min. hike, then you swim into the cave. Then hike, crawl, swim & climb ladders to the "underworld" where the Mayas believed the gods lived. In the cave is The Cathedral, where skeletons of sacrificed Mayas have rested for over 1k years. "The Crystal Maiden," skeleton is calcified, giving it a sparkling, surreal appearance. #PinUpLive
