Cold water kelp forests, sea caves, and wild islands close to California yet worlds apart
Overview
Channel Islands National Park and the surrounding national marine sanctuary protect five remote islands and cold water kelp forests just off the Southern California coast. Year round boat access from Ventura and Oxnard opens up rich scuba, freedive, and snorkel adventures among sea lions, giant sea bass, and colorful invertebrates. On land, hikers find quiet ridgelines, sea cliffs, and endemic wildlife. Expect cool water, variable wind, and a strong conservation ethic shaped by marine protected areas that cover about a fifth of local waters.
Dense kelp and rocky reefs hold rockfish, sheephead, invertebrates, plus occasional pelagics for wide-angle and macro.
Thirteen MPAs cover about 21% of waters, with several no-take reserves open for diving and snorkeling.
With no public airstrips or car ferries, you reach the islands by ferries and charter boats, keeping crowds low.
Mild Mediterranean weather around mid-18°C air supports year-round trips with shifting wildlife and viz.
