About COW FLATS Hot Springs

COW FLATS Hot Springs offers an authentic Idaho experience with its naturally heated waters simmering around 138°F. Set amidst rugged terrain, this primitive hot spring invites you to soak in its steamy pools while surrounded by expansive wilderness, delivering a raw connection to nature.

Getting There

Access requires a bit of effort, involving a moderate hike through forested trails that can be slippery in wet conditions. There is no formal parking lot, so prepare for limited space along the nearby roadside, and watch for livestock since the area is used for grazing.

What to Expect

The pools themselves are rustic and unmaintained, formed by natural rock formations that collect the hot water. The atmosphere is quiet and secluded, usually attracting a small group of adventurers. Facilities are minimal—bring everything you need as there are no restrooms or developed amenities at this Idaho swimming hole.

Tips for Visitors

Plan your visit in the cooler months when the contrast between air and water temperatures enhances the soothing effect. Carry plenty of water to stay hydrated and sturdy shoes for the hike. Remember, no fees or permits are required, but always practice Leave No Trace principles to preserve this pristine hot spring.
