We start the tour from your hotel and head towards the Sumidero Canyon, where we will take a 2-hour boat ride through the Sumidero Canyon to the Grijalva River dock, where you can observe the local flora and fauna. As we progress through the tour, we will stop at a 16th-century fountain designed in the Mudejar style as we approach the historic city of Chiapa de Corzo, founded by Captain Diego de Mazariegos in 1528. We take advantage of the opportunity to continue our tour and visit 3 of the 5 viewpoints that make up the Sumidero Canyon to end the tour. Return at approximately 6:00 pm.
