Utah Mighty 5 vs Colorado Rockies

Utah's Mighty 5 is the classic Southwest road trip: five national parks strung across roughly 400 miles of red-rock desert, each completely different from the last. Start in Zion, where the Virgin River has carved a sheer sandstone canyon you explore by shuttle, then climb to Bryce Canyon's amphitheaters of orange hoodoos at more than 8,000 feet. Scenic Byway 12, one of the most beautiful drives in the country, carries you to Capitol Reef, a quieter park of cliffs, petroglyphs and pioneer orchards near the small town of Torrey. The trip ends in Moab, base for Arches and its 2,000-plus stone arches and for Canyonlands, where the Island in the Sky mesa looks down on the Colorado and Green rivers. Most travelers fly into Las Vegas or Salt Lake City, rent a car and spend about a week, sleeping in Springdale, Bryce or Tropic, Torrey and Moab. Plan ahead: Arches uses a timed-entry system in its busy season, Angels Landing needs a permit, and summer afternoons regularly top 100°F (38°C), so early starts, plenty of water and spring or fall dates make the biggest difference.

The Colorado Rockies pack big mountain scenery within easy reach of a lively city, which makes them perfect for a long weekend. Start in Denver, the Mile High City, where food halls, breweries and green-chile-smothered everything have turned neighborhoods like RiNo, LoHi and Union Station into a serious food scene. Just 30 minutes west, Red Rocks Amphitheatre sits between towering sandstone slabs and is one of the world's most famous places to see a concert, or simply to climb the stairs at sunrise. From there the mountains take over: Trail Ridge Road in Rocky Mountain National Park climbs past 12,000 feet above treeline, and the old mining towns of Idaho Springs and Georgetown, plus the gateway town of Estes Park, make charming bases. With more time, head to Breckenridge, Vail, Glenwood Springs' hot springs pools, Aspen's Maroon Bells and the red rocks of Garden of the Gods near Colorado Springs. Plan ahead: Rocky Mountain National Park requires timed-entry permits in summer and early fall, the Maroon Bells need a shuttle or parking reservation, and the altitude is real, so drink plenty of water and take the first day easy.
