Carlos was our affable guide. I don't think we could have made it safely to the top without him.. He lives in Cabuya, but his grandfather runs the parking lot at the base of the trail, so if you ask him, he will get Carlos there to guide you. We hiked all the way to the top and did some swimming. I would do it again in a hearbeat. I can't imagine anyone making the trip to Montezuma without doing the falls.
