On the morning we were scheduled to visit the Sumidero Canyon, Lucero, the administrator of Cepsu called to advise the tour had been cancelled due to bad weather. She quickly rearranged our day to visit 2 indigenous communities, and our family of 4 ended up having a private tour. Our tour guide, Nahum, was professional, courteous, knowledgeable and very pleasant to spend the day with. He gave us a lot f information about the two communities we visited. We had an extremely interesting day, despite the bad weather.
I highly recommend this tour company. They are professional and a pleasure to deal with. Our trip to Chiapas was made all the more enjoyable thanks to them.
