This earthen fort at Oregon's northwestern tip was built during the Civil War to guard the Columbia River against attack. None came until World War II, when a Japanese submarine fired upon it. The fort still has cannons and an underground gun battery, of which tours are available in summer (call for details). The park has year-round camping, with full hookup sites and 15 yurts. There are also bike paths, boating, swimming, hiking trails, and a short walk to a gorgeous, wide beach where the corroded skeleton—or the tiny bit that remains of it—of the Peter Iredale pokes up through the sand. This century-old English four-master shipwreck is a reminder of the nearly 2,000 vessels claimed by these treacherous waters.
