Discover the wild beauty of the Channel Islands off the Ventura and Santa Barbara coast — including hiking, wildlife, camping, and boat tours to the islands.
Just off the coast of Southern California lies one of the most breathtaking and least visited national parks in the United States — Channel Islands National Park. Often called the “Galápagos of North America,” the park protects five remarkable islands filled with dramatic sea cliffs, pristine beaches, marine wildlife, and rare species found nowhere else on Earth.
Located off the shores of Ventura and Santa Barbara counties in California’s 805 region, the Channel Islands offer outdoor adventure, solitude, and untouched natural beauty that feels worlds away from the busy mainland.
Whether you're interested in hiking coastal bluffs, kayaking through sea caves, spotting whales, or camping beneath the stars, the Channel Islands provide one of the most unique outdoor experiences in California.
This guide covers everything you need to know about visiting the islands, including the best things to do, how to get there, and boat tours and charters that depart from the mainland.
Where Are the Channel Islands?
The Channel Islands sit between 11 and 55 miles off the Southern California coast, stretching across the Pacific Ocean west of Ventura and Santa Barbara.
Eight islands make up the Channel Islands archipelago, but five islands are protected within Channel Islands National Park:
The remaining islands — San Nicolas Island, Santa Catalina Island, and San Clemente Island — are not part of the national park.
Most visitors access the islands by boat from Ventura Harbor, Channel Islands Harbor in Oxnard, or Santa Barbara Harbor.
