Zion National Park is always open; park facilities' hours vary by season. The entry fee is $25 per vehicle and is valid for seven days. High season is April through September. From April to October, Zion Canyon can only be accessed by a free shuttle bus; the rest of the year you may drive a private vehicle. The closest major airport is McCarran International Airport (LAS). Springdale, Utah is the service-oriented town next to the park. Zion's animals are wild; it's illegal and dangerous to approach, touch, or feed them. The bottom of Zion Canyon is located at 4,000 feet altitude, and the park’s mountains rise another 3,000-plus feet. Reservations are necessary for the Zion Lodge and camping.
