Lolo Hot Springs is a natural thermal spring resort in Lolo, Montana, situated on US Highway 12 in the Bitterroot Mountains near the Idaho border, at a location historically significant as the route taken by the Lewis and Clark Expedition on their journey to and from the Pacific Ocean in 1805–1806 — the explorers camped and bathed at these very springs, recording them in their journals as a welcome relief after crossing the challenging Bitterroot Mountains. The chloride-mineralised spring waters feed outdoor soaking pools in a mountain forest setting alongside the Lolo Creek, maintaining comfortable bathing temperatures year-round in a landscape of ponderosa pine and Engelmann spruce that has changed little since the Corps of Discovery passed through. The Lolo Trail — the ancient Nez Perce Indian highway across the Bitterroot Mountains used by Lewis and Clark — passes through the area and is now a designated National Historic Landmark, making the hot springs a natural rest stop on one of America's most historically significant wilderness routes. Lolo Hot Springs offers a genuinely historic natural bathing experience in a Montana mountain setting that connects bathers to one of the most celebrated journeys in American exploration history.
