Alex was our tour guide for two tours: Sumidero Canyon on April 18 and the Mysteries of Palenque tour on April 22. The tour and Alex were perfect. Alex was knowledgeable, punctual and very helpful. Alex was great at having the perfect balance of providing information without being overwhelmingly chatty. He was also very helpful in having suggestions for things to see and do in San Cristobal de la Casas. I would highly recommend Alex for anyone going to the Chiapas area. Thanks Krista
