Be ready for pickup at yourSan Crist□bal hotel at 9am to start the tour. Drive west about an hour to reach Sumidero Canyon, a canyon inside a national park where the Grijalva River meanders through a narrow gorge with walls up to 3,280 feet (1000 meters) high.

Travel through Sumidero Canyon on a 2.5-hour boat ride and admire the scenic views of the deciduous rain forest. Look for wildlife including river crocodiles. Learn about the canyon’s natural history (Spanish-only narration) and how it formed around the same time as the Grand Canyon in the United States.

Afterward, head to Chiapa de Corzo, one of Mexico's Pueblo M□gicos, or magic towns. Explore this colonial city on the banks of the Grijalva River for an hour or so, stopping in to Santo Domingo Church, a former monastery built by Dominican friars in the 16th century. Stroll around the central plaza and see the famous La Pochota, a centuries-old kapok tree around which the town was founded. Admire La Pila fountain, a beautiful Moorish structure built in 1562. Buy some souvenirs before heading back to downtown San Cristobal, where the tour ends.
