Arches National Park is 48 miles from Green River.
A red rock wonderland containing some of the most scenic and inspiring landscapes on Earth, Arches National Park contains the world’s largest concentration of natural sandstone arches. Although over 2,000 arches are located within the park’s 76,518 acres, the park also contains an astounding variety of other geological formations. Colossal sandstone fins, massive balanced rocks, soaring pinnacles and spires dwarf visitors as they explore the park’s viewpoints and hiking trails. Geologic faulting has exposed millions of years of geologic history within the park.
