Overview Tucked away in a canyon to protect visitors from strong northwest winds, Water Canyon Campground offers exceptional island views, access to spectacular hiking opportunities and a nearby white sand beach. Located 40 nautical miles from the Channel Islands National Park visitor center in Ventura, Santa Rosa is the second largest island in California at approximately 53,000 acres in size. The island landforms support a diverse array of plant and animal species including six plant species found nowhere on earth but Santa Rosa Island. The island also hosts over 100 bird and three land mammal species, including the endemic island fox. Recreation Several trails and roads traverse the island, providing visitors with spectacular hiking opportunities, including the relatively flat route to Water Canyon Beach to the rugged, mountainous path to Black Mountain. Due to the strong, persistent wind, swimming, snorkeling, diving and kayaking are limited and recommended for the experienced visitor only. Despite the wind, Santa Rosa Island offers exceptional beach walking on white sand beaches.
