Channel Islands National Park

Log in to track your visit to Channel Islands National Park.

Channel Islands National Park protects five of the eight Channel Islands scattered off the Southern California coast — Anacapa, Santa Cruz, Santa Rosa, San Miguel, and Santa Barbara — along with a mile of surrounding ocean, totaling nearly 250,000 acres mostly underwater. Often called the "Galapagos of North America," these islands were separated from the mainland over 10,000 years ago as sea levels rose, allowing plants and animals to evolve into forms found nowhere else on Earth. Established as a national park in 1980, the islands have no roads, no cars, no hotels, and no services of any kind — just 145 miles of wild coastline, ancient Chumash archaeological sites, and a wildlife density that can seem almost unreal. Santa Cruz Island, the largest at 96 square miles and jointly managed with The Nature Conservancy, is the most visited; Anacapa, with its iconic lighthouse and dramatic sea arch, is closest to the mainland. Each island has its own character, ecology, and set of hiking trails and sea caves to explore. Reaching any of them requires a boat or seaplane — a natural filter that keeps the Channel Islands among the least crowded destinations in the California national park system despite being within 25 miles of Los Angeles and Ventura. If you've lived in Southern California and never visited, these islands are your reward for finally making the trip.

Sea kayaking the sea caves of Santa Cruz Island is the park's most celebrated activity. Painted Cave — one of the largest and deepest sea caves in the world at over a quarter mile deep — can be paddled by kayak at low tide, its walls streaked with colorful algae and lichen that justify the name. Kayak rentals and guided tours are available through Island Packers or Aquasports. Snorkeling and scuba diving around the giant kelp forests bring you face-to-face with bat rays, garibaldi (California's brilliant orange state marine fish), lingcod, and the occasional harbor seal. Hiking on Santa Cruz includes the Potato Harbor Trail (4.5 miles round trip) with cliff-edge views and the Scorpion Canyon Loop for beach access. Anacapa's Inspiration Point trail (1.5 miles) delivers panoramic views of neighboring islands and whale migration routes. Whale watching from the concessionaire boats is excellent January through March (gray whales) and May through October (blue and humpback whales). Birdwatching on all islands during seabird nesting season (spring) is world-class.

The Channel Islands fox — a miniature subspecies of the gray fox found only on six of the Channel Islands — was brought back from the brink of extinction in a landmark recovery effort; today it is the most abundant native land mammal on the islands and remarkably fearless around humans. California sea lions and harbor seals haul out by the hundreds on rocky beaches. Northern elephant seals breed on San Miguel Island each winter in one of the largest colonies on the Pacific Coast. Thousands of seabirds nest on Anacapa, including Brandt's cormorants, western gulls, and brown pelicans. The surrounding kelp forest ecosystem supports over 1,000 marine species.

There is no entrance fee for the park itself, but boat transportation is required. Island Packers (island-packers.com) operates daily ferry service from Ventura and Oxnard — reserve well in advance for spring and summer weekends. Day trips to Anacapa run about 3 hours round trip; Santa Cruz day trips are about 4 hours with several hours on the island. Camping is available on all five islands with advance reservation through Recreation.gov; bring everything you need including all water. The best overall season is spring (April–June) for wildflowers, seabird nesting, and whale migration. Summer is warmest and calmest for kayaking.

Island Packers departure points are in Ventura Harbor (1691 Spinnaker Dr., Ventura, CA) and Channel Islands Harbor in Oxnard. Ventura is 60 miles northwest of Los Angeles via US-101. Los Angeles International Airport (LAX) and Burbank (BUR) are the nearest major airports. Truth Aquatics in Santa Barbara also offers seasonal boat service to the northern islands. A seaplane service (Channel Islands Aviation) flies to Santa Rosa Island from Camarillo.

Bring all water you'll need for the day — there is no potable water on Anacapa or most other islands (Santa Cruz Scorpion Ranch is the exception). Pack for rapidly changing weather: coastal fog, wind, and sun can all occur on the same afternoon. Seasickness is real on the crossing — take medication an hour before departure if you're prone to motion sickness. Book ferry tickets as early as possible; popular dates sell out months in advance. The Channel Islands fox is harmless and curious but do not feed it — the success of the recovery program depends on keeping the animals wild.
