Colorado Rockies vs Pacific Coast Highway

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.

Driving the Pacific Coast Highway from Los Angeles to San Francisco is the classic American road trip, a roughly 450-mile ribbon of asphalt that clings to cliffs, dips into surf towns and threads some of the most dramatic coastline on Earth. Start with the beach cities of Santa Monica and Malibu, then roll north to Santa Barbara's red-tile roofs and its graceful Spanish mission. Next come the laid-back college town of San Luis Obispo and the wide sands of Pismo Beach, followed by the hilltop opulence of Hearst Castle and hundreds of elephant seals lounging on the beach at Piedras Blancas. The highlight is Big Sur, where Highway 1 winds high above the ocean past McWay Falls and the arching Bixby Creek Bridge before reaching storybook Carmel-by-the-Sea and the world-class Monterey Bay Aquarium. Five days is the sweet spot for the drive, with extra days for San Francisco, Napa Valley wine country and the coast south of the city. One important warning: landslides regularly close sections of Highway 1 in Big Sur, so check Caltrans QuickMap before you set out and be ready to detour inland on US-101 or do Big Sur as an out-and-back from Carmel.
