Fort Stevens was once the primary military defense installation in the three-fort, Harbor Defense System at the mouth of the Columbia River (along with Forts Canby and Columbia in Washington). The fort saw service for 84 years, from the Civil War to World War II. Today, Fort Stevens has grown into a 4,300 acre park offering exploration of history, nature, and many recreational opportunities.
Camping, beach-combing, freshwater lake swimming, trails, wildlife viewing, a historic shipwreck, and a historic military fort make Fort Stevens a uniquely diverse park. The park also has a network of nine miles of paved bicycle trails and six miles of hiking trails that allow for exploring a variety of habitats including spruce and hemlock forests, wetlands, dunes, and shore pine areas.
