Less than 20 minutes from Tuxtla Gutiérrez, the state capital of Chiapas, is one of Mexico’s most impressive natural attractions: the Sumidero Canyon. The Grijalva River runs through the canyon gorge, where local flora and fauna abound, including crocodiles, ocelots, spider monkeys, white-tailed deer, and a great variety of waterfowls. Here are some photos that will make you want to add the Sumidero Canyon to your bucket list.
