History of Ohanapecosh Hot Springs
The name Ohanapecosh derives from a Taidnapam word whose exact meaning remains debated, though connections to the river and landscape are clear. Early park visitors bathed in these springs before facilities closed in the 1960s to protect the thermal features and surrounding environment. An interpretive boardwalk now allows observation while preventing damage to the fragile spring area.
Visit the springs May through October when State Route 123 is open. Ohanapecosh Campground sits 1 kilometer away with reservable sites beneath old-growth forest. The Grove of the Patriarchs trail remains closed pending bridge replacement, but Silver Falls and other hikes offer excellent alternatives. Winter brings road closures and deep snow.
