If you're in Guatemala and are looking for some heart pumping adventure, it's worth the trek to the Kan'Ba Caves at Semuc Champey. These caves are located near the small village of Lanquin deep in the Guatemalan jungle and a guide is required to enter the area. Here your group will be guided through a labyrinth of caverns and tunnels while wading chest deep (and often deeper) through dark waters lit only by the candle you are holding. It's not for the faint of heart as there are rock ledges, waterfalls and rope ladders to navigate and at one point you have to drop through a small opening in the rocks to a pool about 15 feet below. Of course this is done in the pitch black because by this time your candle has been snuffed. If your idea of fun is an experience reminiscent of the Goonies movie then this is something you can't miss!
