San Juan Island National Historical Park preserves key sites of the 1859 Pig War boundary dispute, offering rich history combined with diverse wildlife viewing and hiking along the scenic shores of the San Juan Islands.
San Juan Island National Historical Park is composed of two separate units on San Juan Island, Washington: the American Camp on the southern tip and the English Camp on the northern end. The park commemorates the peaceful resolution of the Pig War, an 1859 border dispute between the United States and Britain. It covers more than 1,700 acres of forest, grassland, and shoreline teeming with native flora and fauna. Visitors can explore well-preserved military sites, historic structures, and interpretive exhibits that recount this unique part of Pacific Northwest history. The park's coastal location offers excellent opportunities for wildlife viewing, including bald eagles, harbor seals, sea otters, and occasional orca sightings in the surrounding waters. Over 14 miles of trails weave through forested hills and open meadows to dramatic viewpoints overlooking the Strait of Juan de Fuca and the Sucia Islands. American Camp features remnants of 19th-century military fortifications, beaches, and black-tailed deer populations, while English Camp preserves British-era barracks and gardens. Recreational activities include hiking, photography, picnicking, and bird watching. The park’s mix of cultural history and natural beauty makes it a favored destination for history buffs as well as outdoor enthusiasts. Access is via ferry or private boat to San Juan Island with well-maintained roads leading to both units. The park operates year-round and offers ranger programs in the summer months. It maintains a quiet, reflective atmosphere with a focus on preservation and education.
