"Battery Point Lighthouse Battery Point was one of the first lighthouses on the California coast, and today its unique island spot makes for a historical visit that doesn't have to be boring. The Del Norte County Historical Society operates the lighthouse and its accompanying museum—open daily during the summer, but strictly on weekends from October to March. Notably, the lighthouse is accessible to the public only during low tide. Guests have to make their way across the land bridge, which can quickly go underwater when the tide comes in. Once on the small rocky island you can check out the lighthouse keeper's home, which has been memorialized as a museum with vintage odds and ends from the days when the lighthouse was operational. Many people also come out simply to admire the natural beauty."
