Fields Spring State Park is a 828-acre (3.35 km2) public recreation area in the northwest United States, located in southeastern Washington on State Route 129, four miles (6 km), south of Anatone. Near the tripoint with Idaho and Oregon, the state park offers various routes to the top of Puffer Butte and its scenic views of the Wallowa Mountains and the Grande Ronde River and Snake River basins. The park was initially developed by members of the local chapter of the Isaac Walton League and workers with the Works Progress Administration.
