Twenty-six and a half miles off the California coast, Santa Rosa Island is west of Santa Cruz Island and east of San Miguel Island. It is the second largest of the Channel Islands (15 miles long, 10 miles wide) and one of the least visited.
From 1902 until late 1986, Santa Rosa was owned by Vail and Vickers. The company used the island as a cattle ranch and ran a hunting operation as well, stocking deer and elk.
The U.S. Government bought Santa Rosa from Vail and Vickers for just less than $30 million. Studies determined the cattle were detrimental to the islands environment and they were removed in 1998; the deer and elk are to be phased out, too.

Ive taken two land trips, one via boat, the other via small plane. Landing on and taking off from the islands dirt airstrip in the wind was quite an experience. Both groups visited several spots around the island, including a couple of Native American middens and a grove of Torrey pines just east of Bechers Bay. (These trees dont grow on any other Channel Island.) In the spring, when the wildflowers bloom and the rolling hills are green, the island is beautiful.
Underwater visibility is often limited off Santa Rosa, so macro photography is the best bet and you wont lack for subjects. At Outside Pinnacles, I shot Corynactis anemones and Hermissenda crassicornis nudibranchs. At other sites, Ive photographed sea cucumbers, clam siphons, fringehead blennies, chestnut cowries, and feather duster worms.
Although the water at Little Wilson Rock was surgy and green, I noted in my log, the marine life is beautiful.
Talcott Shoal, north of the islands western most point, has long been know as a prime lobster hunting area.
A rocky outcropping with two pinnacles rising five and ten feet above the waters surface, Bee Rock, which I have never dived, gets rave reviews from those who have for its colorful and abundant macro life.
Santa Rosa Island hosts several shipwrecks, including the Aggi, Golden Horn, Dora Bluhm, Chickasaw and Crown of England. All of them are in 50 feet of water or less and parts of at least one, the Chickasaw, can be seen on shore.
Little remains of any of them and they can only be visited when the wind dies down and the seas are calm. And remember, this is a National Park and a National Marine Sanctuary, so the taking of artifacts (or anything not on Fish and Game regulations) is forbidden.
Santa Rosa diving is not for the thermal challenged; the words most often noted in my logbooks after dives here are cold, very cold! But the cold, nutrient rich waters are the reason marine life thrives here and why the diving is extraordinary.
