Five islands off the coast of Southern California, teeming with wildlife and ancient Chumash heritage.
July–October: calmer seas, clear water for snorkeling and the most reliable boat crossings. December–April is gray whale season.
Summer weekends sell out camping and boat seats, though the islands never feel as crowded as mainland parks.
Spring winds can cancel crossings, winter storms bring rough seas, and fog (“June gloom”) is common in late spring.
General patterns — conditions vary by year. Check current NPS alerts and road status before you go.
Distances are rough estimates to the closest entrance. Check road and ferry conditions before you go.
Campgrounds inside the park are booked through Recreation.gov, and many fill months ahead.
