Just 55 miles northeast of Las Vegas is the Valley of Fire State Park. The Valley of Fire covers more than 42,000 acres of haunting sandstone formations created from sand dunes that settled in and solidified here during the time of dinosaurs. Human occupation of the valley dates to 3,000 years ago. The park contains numerous rock drawings scratched on its red sandstone by ancient people of the Pueblo culture. The hiking trails through Valley of Fire State Park lead to petroglyphs, unique rock formations, and stunning views. The park is known primarily for its red rock. There is a modern visitors center here, picnic areas, and campsites. Take Interstate 15 north from the city and head east on the Valley of Fire Highway.
