Sumidero Canyon Boat Trip

The Sumidero Canyon boat trip departs from the embarcadero in Chiapa de Corzo, about 70 km from San Cristóbal de las Casas and 15 km from Tuxtla Gutiérrez, making it reachable either as a half-day add-on from Tuxtla or a fuller half-to-full day from San Cristóbal. Independent travellers take a colectivo to Tuxtla Gutiérrez and a short taxi or second colectivo on to the dock, while a direct shared tour van from Real de Guadalupe agencies in San Cristóbal covers the whole route with the boat ticket included. Boats leave the dock once full rather than on a fixed schedule, so arriving in the morning gives the best chance of a quick departure and avoids the afternoon heat. The two-hour launch runs beneath sheer canyon walls that rise more than a kilometre above the Grijalva River, passing the mineral-streaked Árbol de Navidad cascade, cave shrines used for offerings, basking crocodiles and troops of spider monkeys along the forested banks. Life jackets are provided and the ride itself requires no exertion beyond sitting in an open launch, though spray and sun exposure call for a hat and sunscreen. After the boat returns to the dock, an hour or two exploring Chiapa de Corzo's colonial plaza and the Mudéjar-brick La Pila fountain rounds out the day within easy walking distance of the embarcadero. Simple restaurants around the plaza serve regional dishes such as cochito and pepita con tasajo, making a natural lunch stop before or after the ride. November through April brings the clearest water and best visibility of the canyon walls, while the water runs higher and browner after heavy September-October rain, which can also affect departure schedules. Visitors prone to motion sickness on open water should sit toward the centre of the boat, and those sensitive to sun should bring a hat, as the launch offers little shade for most of the two-hour run.
