The Cañón del Sumidero National Park is a Mexican ecological reserve and National Park on the Usumacinta River, in the central Chiapas highlands. The park's centrepiece is Sumidero Canyon, accessible by boat from the township of Chiapa de Corzo, in the central region of the state of Chiapas. American crocodiles (Crocodylus acutus) are among the park's most notorious and sometimes enormous inhabitants.
