It could be argued that, given the conditions of the roads here, pretty much everything in Guatemala outside of Antigua and Guatemala City is "off the beaten path." Still, for a sight worth all the headaches that speed-bumps, slow trucks and long, unpaved, one-way roads can elicit, make the journey to Semuc Champey. Here, along this 300 m limestone bridge that covers the Cahabón River, you'll discover seven tiered, natural swimming pools in the heart of the Guatemalan jungle. If the thought of diving into these spring-fed emerald waters doesn't pique your spirit for adventure, bear in mind that you can also hike/swim through some cool candle-lit caves as well; and all this performed to the cacophony of distant howler monkeys while tiny fish nibble the dead skin off your toes. Sound memorable? That's because it is.
Getting to Semuc will be the real challenge, although a steadier stream of recent visitors has already increased its name recognition and made group travel to the falls significantly more accessible. Your most likely point of entry will be the city of Coban, from which you'll have to make the drive eastward to Lanquin and then on to the natural monument. It's slow going and stressful, there's no two ways about it, but sometimes that's what makes the best ones what they are. Just make sure you give yourself a few days to truly appreciate the experience, which is more than worth the investment.
