Pacific Coast Highway vs Yellowstone and Grand Teton

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.

Yellowstone and Grand Teton sit side by side in northwest Wyoming, linked by a short parkway, and together they make one of the great American road trips. Yellowstone, the world's first national park, holds more than half the planet's active geysers, including Old Faithful, plus the rainbow-colored Grand Prismatic Spring, the thundering Lower Falls of the Grand Canyon of the Yellowstone and terraced hot springs at Mammoth. It is also the best place in the Lower 48 to see big wildlife: bison herds in Hayden and Lamar valleys, elk, pronghorn, bears and, with patience and a spotting scope, wolves. Just south, Grand Teton's jagged peaks rise straight out of the valley floor above Jackson Lake and Jenny Lake, with sunsets that rival anything in the West. Fly into Jackson Hole or Bozeman, rent a car and plan on long but rewarding drives. Neither park uses timed entry, but in-park lodging books up months ahead, parking at Old Faithful and Grand Prismatic fills by late morning, and most of Yellowstone's roads close to cars from early November to late April, so summer and early fall are the main seasons.
