Arrival

Getting There

California is served by several major international airports and extensive overland routes.

By Air

  • Los Angeles (LAX) The busiest gateway, with nonstop routes from virtually every major city worldwide. Located 17 miles southwest of downtown.
  • San Francisco (SFO) Primary hub for Northern California. Strong international connectivity across the Pacific.
  • San Diego (SAN) Compact, easy-to-navigate airport in the heart of the city. Good connections to Mexico.
  • Sacramento (SMF) Best arrival point for Gold Country, Napa Valley, and the Sierra Nevada foothills.

By Road & Rail

  • Amtrak Coast Starlight Seattle to Los Angeles in around 35 hours, passing through Sacramento and the Central Valley.
  • Amtrak Pacific Surfliner Runs along the Southern California coast between San Diego, Los Angeles, and San Luis Obispo.
  • Interstate 5 (I-5) The main north–south spine from Oregon to San Diego. Fast and inland.
  • US Highway 101 The historic coastal route, slower than I-5 but scenic through the Bay Area and wine country.

Seasons

Best Time to Visit

California's climate varies dramatically by region — there's no single "best" time for the whole state.

Pro tip: Shoulder seasons (April–May and September–October) offer the best balance of good weather, manageable crowds, and lower accommodation prices at most California destinations.

Spring (Mar–May)

  • Best for: Wildflower blooms in Anza-Borrego and the Antelope Valley; coastal fog lifts; waterfalls at peak flow in Yosemite.
  • Watch out for: Lingering Pacific storms through March; crowded parks on spring break weekends.

Summer (Jun–Aug)

  • Best for: Beach destinations; Lake Tahoe; high alpine trails accessible once snow clears.
  • Watch out for: Extreme heat in Death Valley (routinely 120°F+); heavy crowds at Yosemite; wildfire smoke can affect air quality.

Fall (Sep–Nov)

  • Best for: Wine harvest in Napa and Sonoma; warm, clear weather along the coast; quieter national parks.
  • Watch out for: Wildfire season peaks in September–October; early snowfall can close mountain passes from October onward.

Winter (Dec–Feb)

  • Best for: Skiing at Lake Tahoe and Mammoth; whale watching along the coast; uncrowded cities.
  • Watch out for: Heavy rain in Northern California; Tioga Road through Yosemite is typically closed November–May.

Transport

Getting Around

Car Rental

  • Essential for most itineraries Outside San Francisco and Los Angeles, a car is effectively required. Public transit does not serve national parks, wine country, or coastal routes.
  • Minimum driving age 21 at most rental agencies. Drivers aged 21–24 typically incur a young driver surcharge.
  • EV charging California has the most extensive EV charging infrastructure in the US — electric vehicles are a practical choice.

Urban Transit

  • San Francisco BART & Muni BART connects SFO airport to downtown in 30 minutes. Muni covers the city's neighborhoods including cable cars.
  • Los Angeles Metro Expanding rail network; useful for Hollywood, downtown, and the Westside. Less comprehensive than San Francisco.
  • San Diego MTS The Trolley connects the airport (via shuttle), downtown, Old Town, and the Mexican border at San Ysidro.

Long-Distance

  • Amtrak The Pacific Surfliner (LA to San Luis Obispo) and Capitol Corridor (San Jose to Sacramento) are genuinely useful and scenic.
  • YARTS (Yosemite) Seasonal bus service from Merced, Mammoth, and Sonora directly into Yosemite Valley — the only option if you lack a timed-entry permit.
  • Greyhound / Flixbus Budget intercity buses connect major cities. Slower but significantly cheaper than Amtrak.

Where to Stay

Accommodation

National Park Lodges

  • Ahwahnee Hotel, Yosemite A National Historic Landmark inside Yosemite Valley. Rooms book out 13 months in advance — plan accordingly.
  • Wuksachi Lodge, Sequoia The only in-park lodging in Sequoia; simple rooms with direct access to the Giant Forest trailhead.
  • Camping Recreation.gov handles all federal campsite reservations, including Yosemite, Sequoia, and Joshua Tree. Reservations open 6 months ahead and fill quickly.

Coastal & City Options

  • San Francisco Union Square and the Embarcadero are most convenient for transit. Pacific Heights and the Mission offer a quieter residential feel.
  • Los Angeles Stay near your primary activities — the city is too large to "base" from one location. Santa Monica suits beach visitors; Silver Lake or Los Feliz suit culture seekers.
  • Big Sur Options are limited and premium — Ventana Big Sur and Post Ranch Inn anchor the luxury end. Reserve months in advance.

Before You Go

Essential Tips

Entry Passes

  • America the Beautiful Pass — $80/year Covers entrance fees at all federal lands including Yosemite, Sequoia, Joshua Tree, and Death Valley. Pays for itself after 2–3 park visits.
  • Timed-Entry Permits Yosemite Valley requires a timed-entry permit from late March through October. Permits are released on Recreation.gov two days in advance at 8 AM PT.
  • California State Parks Pass Separate from federal pass. Worth it if visiting Malibu Creek, Crystal Cove, or other state-managed sites.

Safety & Preparedness

  • Fire conditions Check CalFire (fire.ca.gov) for active wildfires and air quality index before entering forested or canyon areas, particularly in summer and fall.
  • Wildlife Black bears are active throughout the Sierra Nevada. Use bear canisters for all food storage while camping; never leave food in vehicles.
  • Sun and heat Desert parks can reach extreme temperatures. Carry more water than you think you need — a minimum of one liter per hour of hiking in hot conditions.
  • Cell coverage Many national parks and rural highways have no cell service. Download offline maps (Maps.me or Google Maps offline) before departure.

Useful Resources

  • Recreation.gov Federal campsite and permit reservations for all national parks.
  • Caltrans QuickMap Real-time highway conditions, road closures, and chain control requirements for mountain passes.
  • AirNow (airnow.gov) Air quality index monitoring — important during wildfire season.
