Zion National Park is located in Springdale, Utah, which is about 300 miles from Salt Lake City.
The park was named Zion, which means “place of refuge,” by the Mormon pioneers who settled in the area.
The landscape of Zion consists of lush vegetation, deep canyons, towering sandstone cliffs, and a restless river.
Over 3 million people visit Zion National Park every year, and the National Park Service works to accommodate them.
