Maple Grove Hot Springs, also known as Hopkins Hot Springs, is a small developed natural hot spring in the Raft River Mountains of Cassia County, Idaho, where lithium- and sodium-rich thermal water feeds a series of outdoor soaking tubs on Bureau of Land Management land. The site is valued by Idaho hot spring enthusiasts for its distinctive mineralogy — the lithium content is exceptionally high — and its quiet rural character amid the sagebrush valleys of southern Idaho. The surrounding landscape of the Raft River Mountains, with their broad forested ridges and wide open basin valleys, provides a quintessentially Intermountain West backdrop for soaking.
Insider tip — Maple Grove Hot Springs (also known as Hopkins) lies in a secluded canyon in the Boise National Forest near Crouch, Idaho, accessible via the South Fork of the Payette River corridor. Multiple soaking tubs are fed by a robust geothermal source, and the pools are maintained through a small private fee operation. Ponderosa pine and granite outcrops frame the setting. The nearby river allows for a bracing cold plunge between soaks.
