• Kirkham Hot Springs is a scenic geothermal area just off Highway 21
• The site features multiple hot pools and waterfalls at the river's edge

Kirkham Hot Springs can be found on the South Fork of the Payette River, across Highway 21, five miles east of Lowman. This spot is both a recreation area and an interpretive site for volcanic activity, where, in addition to soaking in the healing mineral water or taking a hot shower in the river's cave, you can also learn about the hot springs' geology and local history.

If you are driving from Lowman, you can stop at a large pullout on your right, just before the Kirkham parking area. There, you will enjoy a scenic view of colorful hills, steaming waterfalls cascading down into the pools, and the river rushing its turquoise waters over the rocky bed.

Should you wish to see this fabulous geothermal area closer and soak in its mineral water, travel 400 feet east to the bridge across the river. At the time of our visit, the bridge was closed to vehicles. At this very bridge, however, begins a 0.3-mile trail leading to the waterfalls and soaking pools. It runs through the site to a viewing platform and then down to the river. Be careful when walking, though – the rocky surfaces are uneven and slippery when wet.

There are only vault toilets in the parking area and no drinking water. There is, however, a beautiful picnic area shaded with Ponderosa pines.

Kirkham Hot Springs Experience

Kirkham mineral water flows out of numerous spots, creating smaller puddles and larger pools and cascading as a waterfall. Water comes out of the source at temperatures between 120°F and 135°F and flows into the man-made soaking pools. The pool temperatures range from 95°F to 110°F.

You will see the first pools as soon as the picnic area near the bridge. The other two smaller pools at the viewing platform are great for children. However, what is considered a highlight of Kirkham Hot Springs are hot waterfalls with multiple rock-and-sand pools by the river.

Please note that the river may overflow some bank pools during the high water season.

Remember that at the springs of the Lowman Ranger District of the Boise National Forest, nude soaking and the use of soap are strictly prohibited. Pets should always be kept on a leash and away from the hot spring pools and runoff areas. No glass containers are allowed at or near the spring.

Kirkham Hot Springs is a popular soaking spot that can get crowded during summer weekends and holidays. Plan your trip wisely.

Lowman Ranger District is a popular destination for outdoor enthusiasts. One of its premier hiking routes, the 35-mile Kirkham Ridge Trail, begins just a quarter-mile away. The South Fork Payette River also offers exciting whitewater rafting, kayaking, and trout fishing opportunities.

Traveling along Highways 21 and 17, a.k.a. the Ponderosa Pine Scenic Byway and the Banks-Lowman Highway, respectively, you will enjoy scenic vistas, wildlife viewing, historical kiosks, numerous trailheads, and many natural hot springs. If you head west from Kirkham Hot Springs, you will find Haven Hot Springs, Pine Flats Hot Springs, and Campground Hot Springs, all easily accessible from the road. Going east toward Stanley, you will discover more geothermal gems like Bonneville Hot Springs, Sacajawea Hot Springs, plus several others near Stanley.
