From the town of Lanquin, the national park of Semuc Champey is a bumpy and winding 40-minute pickup-truck ride into the jungle—and definitely not for the faint of heart. Hidden deep in the Guatemalan jungle is a turquoise paradise of natural pools, caves, and waterfalls.The water is from the Río Cahabón, and much more of it passes underground, beneath the bridge. Though this bit of paradise is difficult to reach, the beauty of its setting and the perfection of the pools, ranging from turquoise to emerald-green, make it worth it. Many people consider this the most beautiful spot in all Guatemala.
