You have just arrived at the airport of Tuxla Guttierez, Chiapas, Mexico half an hour ago. Now you are on a highway snaking its way upwards 2500 meters, on your way to San Cristobal de las Casas, the home of the Zapatistas and the central meeting ground for the local indigenous groups like the Chamulas. On your right you can see the world falling away as you get closer to the clouds. It is your first time here. You have read the travel guides, and searched the internet for things to do.
