A few miles east of Tuxtla Gutierrez is the spectacular Cañon Sumidero, created by the mighty Rio Grijalva which runs northwards through it.
Cañon Sumidero can be toured by boat on the river that runs through it, or from above, by the beautiful lookouts and trails.
The 2-3 hour round trip on the boat will take you on a spectacular journey through the canyon, with some of the walls towering 2,500 feet (760 m) above you. Your boat may take you on a tour past one or two caves. The wildlife you will see is equally as spectacular which includes crocodiles and spider monkeys.
If you want to get a bird's-eye view of the canyon, travel by car to 'miradores', where there are 6 viewing points located in the national park. A new Ecological Park has been opened inside the canyon. The only way to get to the park is by boat.
The most common embarkation point is at Chiapa de Corzo, a 40-minutes drive from Tuxtla Gutierrez.
CHIAPA DE CORZO
Chiapa de Corzo is known as the peaceful colonial town on the banks of the Rio Grijalva. It was the first city ever founded by the Spanish in the State of Chiapas (1523) founded by the Spaniard, Diego de Mazariegos. As the story goes, when his army invaded the local indigenous peoples' settlement a few kilometres downstream from here, they all jumped to their deaths in the canyon rather than surrender to his forces. Mazariegos eventually left to found what is today San Cristobal de las Casas, preferring the climate and less hostile reception he encountered there.
If you travel to Chiapas in January, a visit to Chiapa de Corzo during the festival of San Sebastian is A MUST. It is one of the most spectacular Mexican traditions.
