1 Best Sight in Southeast Nevada, Nevada

Valley of Fire's jumbled rock formations are remnants of hardened sand dunes more than 150 million years old. You find petrified trees and one of the park's most photographed features—Elephant Rock—just steps off the main road. Mysterious petroglyphs (carvings etched into the rocks) are believed to be the work of the Basketmaker and early Puebloan people, with their occupation in the area estimated from 300 BC to AD 1150. The easy, essential trail is Mouse's Tank, named for an outlaw who hid out here and managed to find water; so will you in cooler months (but not for drinking). It's a short walk with views of petroglyphs and shaded by steep canyon walls. Sci-fi fans also might recognize Fire Canyon as the alien planet in Starship Troopers and several other movies.

The Valley of Fire Visitor Center was remodeled in 2011 and has displays on the park's history, ecology, archaeology, and recreation, as well as slide shows and films, and information about the two campgrounds (72 campsites, 20 of them with power and water for RVs) within the park. Campsites at Atlatl Rock and Arch Rock Campgrounds are available on a first-come, first-served basis. The park is open year-round; the best times to visit, especially during the heat of summer, are sunrise and sunset, when the light is truly spectacular.
