A:This 1,800-acre preserve is a patchwork of bluffs, beach, lakes, and old growth forest, complete with two historic lighthouses. It occupies a narrow peninsula on Washington’s southwestern tip, where the Columbia River joins the Pacific. And while Cape D may be the state’s most popular park, it’s virtually empty in the evenings when the crowds go home. Stay in one of the park's yurts, which are roomier and more luxurious than a cabin or a tent. Rates start at $62 a night.
