Jerry Johnson Hot Springs

Tucked into the dense forest of the Clearwater National Forest in north-central Idaho, Jerry Johnson Hot Springs is one of the Pacific Northwest's most rewarding natural soaks. A one-mile trail winds through old-growth conifers along the banks of the wild Lochsa River before delivering you to a series of geothermal pools where steaming, mineral-rich water bubbles up from the earth and mingles with the cool, clear flow of Warm Springs Creek. The result is a collection of rustic, undeveloped pools with varying temperatures — some almost too hot to enter, others perfectly tempered by the creek — set against a backdrop of moss-draped boulders and towering pines.

The Setting and Landscape

The journey to the springs is half the experience. The forested trail hugs the Lochsa River corridor, one of Idaho's most scenic and undisturbed river valleys, where the sound of rushing water follows you the entire way. In autumn, the hillsides erupt in amber and gold, and the steam rising from the pools creates an almost otherworldly contrast against the crisp mountain air. Winter transforms the scene into something truly magical — snow clings to the tree branches overhead while you sink into water that hovers between 100 and 110 degrees Fahrenheit. Even in summer, when long daylight hours invite more visitors, the forested canopy keeps the atmosphere intimate and wild. Keep your eyes open along the trail: this corridor is rich with birdlife and occasionally graced by deer, elk, and other wildlife drawn to the river.

The Water and the Soak

The pools at Jerry Johnson are entirely natural and undeveloped — no concrete, no railings, no signage directing you where to sit. Geothermal water seeps from the ground in several locations, forming shallow to waist-deep pools that visitors have shaped over the years with stacked rocks and natural channels. Because the temperature in each pool depends on its proximity to the hot source and the mixing of creek water, you can move between pools to find your perfect temperature. The water carries the faint mineral character typical of geothermal springs, and the clarity is generally good, with a natural sandy and rocky bottom beneath your feet. This is a backcountry soak in every sense — raw, unhurried, and deeply restorative.
