Pacific Coast Highway vs San Francisco

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.

San Francisco packs world-famous sights into a compact, hilly peninsula wrapped in fog and bay views. Ride a clanging cable car up Nob Hill, then drop toward the water for sourdough bread bowls of clam chowder at Fisherman's Wharf. Book Alcatraz well ahead, because the ferry to the former prison island and its gripping audio tour sell out weeks in advance. Walk or bike across the Golden Gate Bridge, coast downhill into Sausalito for seafood by the bay and ride the ferry home past the skyline. Give a full day to wine country, sipping Cabernet in Napa Valley or Pinot Noir in laid-back Sonoma, and save a morning for the towering coast redwoods of Muir Woods, where parking or shuttle reservations are required, or swap in the cliffs and beaches of Half Moon Bay. The city itself rewards slow wandering: dim sum in Chinatown, espresso in North Beach, murals in the Mission and sunset at Ocean Beach. Pack layers whatever the month, since summer fog can drop temperatures into the 50s while the sun shines a few miles inland, and wear comfortable shoes for the steep hills. September and October usually bring the warmest, clearest days of the year.
