Loftus Hot Spring is tucked within Boise National Forest, Idaho, a vast mountain woodland. Its iron-rich water surfaces at around 38°C in an open-air pool suited to wild bathing.
Insider tip — The Boise National Forest in southwestern Idaho is a vast mountain wilderness of ponderosa pine forests, granite peaks, and clear rivers shaped by the ancient Idaho Batholith volcanic intrusion. Loftus Hot Spring emerges from the geothermal legacy of this volcanic terrain, providing iron-rich thermal bathing in the forested mountains above Boise — one of the American West's fastest-growing cities that seeks refuge in its spectacular natural wilderness hinterland.
