Fort Canby (now known as Cape Disappointment) bears the distinction as the state’s first military installation. Constructed in 1852 to guard the mouth of the Columbia River, it was part of the defensive triad that included Fort Columbia and Fort Stevens (located on the Oregon side of the river.) The confluence of the Columbia and the Pacific Ocean was a historically significant destination that attracted Native peoples, European explorers, and the famed Lewis and Clark Expedition. This state park preserves some scattered remnants of the fortification, the oldest functioning lighthouse in the state built in 1856 (Cape Disappointment Lighthouse), and North Head Lighthouse. One of the park’s significant attractions is the Lewis and Clark Interpretive Center that is sited on the bluffs overlooking the merging waters of river and ocean. It was near this point on November 7, 1805, that Lewis and Clark first glimpsed the Pacific Ocean.
Fort Canby State Park is located on the Washington side of the Columbia River, two miles southwest of Ilwaco off US Hwy. 101.
