Sumidero Canyon National Park

Sumidero Canyon National Park protects a 1,000-meter gorge carved by the Rio Grijalva in Chiapas, featuring dry tropical forests, cave-nesting swifts, and riparian habitats supporting crocodiles and tapirs. The Christmas Tree Cave, a green algae formation visible from boat tours, provides a unique attraction unmatched in the region. With over 1,500 recorded species, it surpasses #6 Nevado de Colima in biodiversity within its canyon ecosystem, boasting 20% more endemic fauna.
