We arrived in Lanquín, Guatemala after being packed like sardines on an 8-hour bus trip from Tikal. The scent of burnt foliage from the ubiquitous slash-and-burn stung our noses as we exited the bus onto the orange mud road that had led us into the depths of the Mayan jungle. We’d come for Semuc Champey (Mayan for Sacred Waters). The clear turquoise lagoon flows from an underground cave in the middle of the jungle, beckoning visitors to bathe with the fish. Colorfully-clad Maya sat at the water’s edge, observing us with reluctant fascination as we graciously explored their sacred oasis.
