Breitenbush Hot Springs Retreat and Conference Center (pronunciation: BRIGHT en BUSH), commonly called Breitenbush Hot Springs or simply Breitenbush, is a worker-owned co-op featuring holistic and spiritual retreats. It is surrounded by the Willamette National Forest in Breitenbush, Marion County, Oregon, United States, 10 miles (16 km) east-northeast of Detroit along the West Cascades Scenic Byway and 12 miles (19 km) northwest of Mount Jefferson. The closest metropolitan area, Salem, is approximately 60 miles (100 km) to the west. The retreat center is located at the site of the Breitenbush Hot Springs, which drain into the adjacent Breitenbush River.
Breitenbush Hot Springs has natural geothermal springs, and was a frequent gathering place for local Native Americans.
The geothermal hot springs result from precipitation onto the surrounding Cascade Range. Analysis of the mineral and chemical content indicates an average subsurface temperature of 356 °F (180 °C) and a migration time of several thousand years.
