Cedar Breaks National Monument

Cedar Breaks is the amphitheater almost nobody drives to - a half-mile-deep bowl of pink, red and orange rock perched above 10,000 feet in southern Utah, about 194 miles and 3¼ hours from Las Vegas. Think Bryce's hoodoo drama with a fraction of the crowd: State Route 148 runs the monument's rim with pullouts at four overlooks, two short trails visit ancient bristlecone pines and an alpine pond, and after dark it's a certified International Dark Sky Park with some of the best stars in the Southwest. Entry is $25 per vehicle for seven days ($20 per motorcycle, $15 per person on foot, under-16s free), card only, no cash.

The defining fact is the season: SR-148 closes to cars with the snow, roughly mid-November to mid-May, leaving winter access to snowshoes, skis and snowmobiles only. July and August bring the famous wildflower bloom (and afternoon thunderstorms; pack a layer, because 10,000 feet ignores summer). It's a half-day monument at the end of a long drive, which is exactly why the right play is a southern-Utah loop: Cedar Breaks pairs with Brian Head next door and Bryce Canyon an hour away, not with a same-day return to the Strip.
