Destination guide
Los Angeles: Beaches, studios and year-round sunshine
Los Angeles is a sprawl of beach towns, hillside neighborhoods and studio lots tied together by freeways. LAX is the main gateway, but Burbank, Long Beach and Orange County airports are smaller, calmer and often closer to where you're staying.
Best time to visit: March–May and September–November have warm, dry days and thinner crowds. June can be gray at the coast ('June gloom'); fall is the warmest beach season.
