Keep reading to learn more about Kirkham Hot Springs and why it’s one of our favorite things to do near Idaho City.
A Brief History of the Springs
Kirkham Hot Springs sits within the Boise National Forest, an area long known for geothermal activity. Natural hot water rises from deep underground through fractures in the earth before spilling down the hillside into a series of mineral-rich pools beside the river. The site has been used recreationally for decades and eventually became a managed Forest Service recreation area because of its growing popularity.
Today, interpretive signs near the springs explain the geothermal features and history of the area, helping visitors understand how the steaming waterfalls and pools formed over time.
The Pools at Kirkham Hot Springs
Number of Pools
Kirkham Hot Springs features multiple natural soaking pools spread across the hillside and along the river’s edge. Visitors can usually expect to find several small to medium rock-lined pools that range from ankle- to waist-deep.
Pool Temperatures
The pools vary greatly in temperature depending on their distance from the hot water source and how much cold river water mixes in. Some pools closer to the source can exceed 110 degrees Fahrenheit and may feel too hot for comfortable soaking, while lower pools near the river tend to stay in a more moderate range around 100 to 105 degrees.
The Waterfalls
One of the most unique features of Kirkham is the hot spring’s waterfalls. Several streams of steaming mineral water cascade over the cliffside into the pools below, creating natural warm showers that visitors can stand beneath.
Kirkham Ridge Trail
The Kirkham Ridge Trail in Boise National Forest is the area’s best-known hiking route and begins less than a quarter mile from the hot springs. Portions of the 35-mile trail are considered moderate to difficult because of elevation gain, but shorter out-and-back hikes are manageable for most hikers with decent fitness levels.
Warm Springs Trail Area
Several smaller informal trails wind around the geothermal area near the springs themselves. These short walking paths allow visitors to explore the hillside, view the steaming seeps, and access different soaking pools. Most are easy walks, though the terrain can become slippery and uneven near the water.
South Fork Payette River Access Trails
Visitors looking for a riverside stroll can explore the nearby access trails along the South Fork Payette River. These short pathways connect picnic and fishing areas while providing scenic overlooks of the rushing water. The terrain is generally easy and family-friendly, though spring runoff can create muddy or slick conditions near the riverbanks.
