Located a few kilometres east of Tuxtla Gutierrez, the capital of Chiapas, the Sumidero Canyon (Cañon del Sumidero in Spanish), has 800 meter-high walls feet) and lots of natural life. Sumidero Canyon's Río Grijalva is a gorgeous landscape.
Fjaðrárgljúfur Canyon, in Iceland. Some geological formations in Earth are simply spectacular. The way our planet adjusts its continents creating breath-taking landscapes all around the world is simply fantastic. Another place I'd love to visit.
