Prisoners Harbor
Prisoners Harbor is an anchorage on the north shore of Santa Cruz Island, the largest island in Channel Islands National Park, where you drop the hook and dinghy ashore into genuinely wild California. The setting is remote and rugged, with trails leading into the island's interior canyons and a newly opened small campground nearby if you want to extend your stay — but there are no dock facilities, so plan to anchor off and tender in.
