VALLEY OF FIRE STATE PARK
One of Nevada's oldest state parks, dedicated in 1935, is a sci-fi--like land of red sandstone and gray limestone formations. Today the stark landscape sees more lizards than it does visitors. Winter, when temperatures are mild, is the best time to go. Delineated hiking trails here are relatively short, but you're free to explore on your own. From Las Vegas, take I-15 55 miles to the park. Or, for a more scenic route, take Lake Mead Blvd. into Lake Mead National Recreation Area ($5 per vehicle); bear left at Northshore Blvd. and continue to Valley of Fire State Park ($6 per vehicle); allow 1 1/2 hours; http://parks.nv.gov or 702/397-2088.
