Part of the Channel Islands, this vast and rugged landmass offers a world of dramatic cliffs, rolling hills, pristine shorelines, and breathtaking vistas that seem to exist in another era.
Here, nature dominates, and time slows down. There are no cars, no hotels, no modern distractions—just raw beauty waiting to be explored. For those seeking solitude, adventure, and a deep connection with nature, Santa Cruz Island is an extraordinary escape.

A Landscape of Stunning Contrasts
Rising from the Pacific like a forgotten paradise, the island’s geography is as varied as it is mesmerizing. Towering sea caves carve into the rocky coastline, hidden coves shimmer in the sunlight, and trails wind through golden grasslands and ancient oak woodlands.
Inland, jagged mountain ridges dominate the skyline, with Devil’s Peak, the highest point on the island, reaching 747 meters (2,450 feet). This is a land sculpted by time, weather, and the unrelenting force of the ocean.
Despite being just 32 kilometers (20 miles) from Ventura, Santa Cruz Island—stretching 249 square kilometers (96 square miles)—feels untouched, a place where the modern world has yet to intrude.

A Journey Through History
Its history stretches back over 10,000 years. Long before European explorers set foot on its shores, the Chumash people called this island home, referring to it as Limuw, meaning “in the sea.” They lived in villages along the coast, crafting plank canoes (tomols) to trade with mainland tribes and surviving on the island’s abundant resources.
Later, Spanish explorers arrived, followed by ranchers who turned Santa Cruz into a hub for sheep farming and winemaking in the 19th and early 20th centuries.
Some of the old adobe ranch buildings still stand, remnants of a past era now overtaken by nature’s slow reclaiming of the land. Eventually, conservation efforts took hold, and today, The Nature Conservancy and the National Park Service oversee the island, ensuring that its beauty and biodiversity remain protected for generations to come.
A Haven for Unique Wildlife
For nature lovers, the largest island in California offers a treasure trove of wildlife found nowhere else on Earth. Its isolation has allowed unique flora and fauna to evolve, making it home to over 60 endemic plant and animal species.
One of its most famous inhabitants is the near-threatened island fox, a tiny predator that was once on the brink of extinction but has since made a remarkable recovery. Santa Cruz Island is also the only place in the world where the island scrub-jay, a brilliantly blue bird, can be found.
Along its shores, sea lions and seals lounge on the beaches, while dolphins and migrating whales glide through the surrounding waters. Beneath the surface, kelp forests teem with marine life, creating an underwater wonderland for snorkelers and divers who venture into its depths.
The Best Things to Do on the Channel Islands of California
How to Get to California’s Largest Island
Getting to California’s largest island is an adventure in itself. Unlike other well-known island destinations like Santa Catalina, there are no daily ferries, no resorts, no beachfront bars.
The only way to visit is by boat, kayak, or private charter, with Island Packers Cruises offering regular trips from Ventura Harbor. The journey across the Santa Barbara Channel takes about an hour, and if you’re lucky, you might see dolphins racing alongside the boat or even a passing whale.
Once on the island, there are no services—no food, no shops, no trash bins—so visitors must bring everything they need and follow the strict Leave No Trace principles.
When to Visit Santa Cruz Island
Choosing the best time to visit depends on what you’re looking for. Spring is spectacular, as the island erupts in a riot of wildflowers, painting the hills in shades of yellow, orange, and purple. Wildlife is at its most active, and the weather is comfortably mild.
Summer brings warm temperatures, making it ideal for snorkeling and kayaking through the island’s famous sea caves – some of the largest in the world.
Autumn offers fewer crowds, with golden grasslands stretching across the hills under deep blue skies. Winter, though unpredictable, brings gray whale migrations, a mesmerizing sight for those who make the journey during this season.
Reasons to Visit the Largest Island in California
There are places in the United States where nature has been tamed, where modern convenience blends seamlessly with scenic beauty. Santa Cruz Island is not one of them. It remains wild, untouched, and completely removed from the distractions of daily life. Stand atop a windswept bluff, and the only sounds you’ll hear are the crash of the waves and the calls of distant seabirds.
Hike through valleys where island foxes dart through the brush, paddle into hidden caves that echo with the sounds of the sea, or simply sit on an empty stretch of beach where the footprints in the sand are only your own.
For those seeking adventure, solitude, or a glimpse into California’s past, Santa Cruz Island remains a place where nature still reigns, unchanged by time.
