At Challis Hot Springs, the choice starts with temperature. One outdoor pool stays in the warm, easygoing range of about 96 to 99 degrees, while a smaller pool runs roughly 104 to 107 degrees. You can settle into the first for a long conversation or a quiet stretch after a drive, then step into the hotter water for a briefer, more concentrated soak.
The setting is along Idaho’s Salmon River, where camping, river sounds and mountain-country recreation give the pools a fuller role than a quick roadside dip. It works as an overnight stop when the road has gotten long, but it also has enough around it to support several unhurried days.
Two pools with different moods
The larger warm pool is the one built for lingering. Its temperature is comfortable enough for a relaxed morning soak or a gradual wind-down after hiking, fishing, trail riding or simply setting up camp. This is soaking water, not a place intended for laps and cannonballs.
The smaller hot pool provides the contrast. At 104 to 107 degrees, it is a place to take a shorter turn, warm up thoroughly, and then move back to the gentler pool or out into the open air. Having both temperatures on the same property makes it easy to set your own pace rather than committing to one very hot bath.
Underfoot, the pools have a concrete base with a pebble-like rock surface. Natural river or creek rock and sand are also part of the pool texture, with spring water percolating up through the bottom. It is a pleasingly unfussy detail: more tactile than a standard slick pool floor, and fitting for a soak beside a river.
Steps and handrails lead into and out of the pools. Both pools are outdoors and exposed to the sun, so a hat, sunglasses or sun-protective clothing can be useful if a long warm-pool session is on the agenda.
The water is kept notably clear, and the pools are drained overnight and refill with warm water by morning. Early soaks have become a small ritual for repeat campers, especially after a travel day or a full afternoon outdoors.
Camping with the Salmon River nearby
The campground runs alongside the Salmon River, and some sites sit directly beside the moving water. The river remains audible from camp, including in the morning, giving an ordinary cup of coffee outside a little more atmosphere than it gets in most RV parks.
RV campers have gravel sites with hookups, and the larger sites are level and edged by grass and shade. Lawns, flowers and mature trees keep the grounds from reading as a bare parking arrangement, while the surrounding landscape supplies the wider Idaho scenery.
Tent camping is available, too. Some tent sites sit a short walk away from the main campground area, creating a quieter pocket for campers who would rather be a little removed from RV traffic and neighboring doors.
Site layouts vary, as they do in many campgrounds, so not every space has the same degree of separation. Still, the grounds have room for stays longer than a single night, and groups can reserve multiple RV sites together for a family gathering or a trip with friends.
When regular spaces fill, the property has an overflow camping area called The Field. It is especially relevant around busy local events, when the campground can take on a livelier, more communal tone.
A good base for an outdoorsy few days
The pools are only one use for the property. Fishing areas are nearby, off-road trails can be reached from the campground area, and a forest walking trail offers a lower-key way to spend time outside. A day can be as active or as idle as you make it.
For many campers, the rhythm is simple: head out for a trail ride, spend time fishing, take a walk through the trees, then return for hot water before dinner. The warm pool is especially suited to this pattern because it invites a longer settle-in after a day on your feet.
Challis Hot Springs also draws people during the Braun Brothers Reunion Concert, when returning visitors use the pools as a restorative stop after the music and crowds. During those busier stretches, the overflow area can come into play.
More than a tent-and-RV stop
Camping is the obvious fit for the riverside setting, but bed-and-breakfast accommodations provide another way to stay. Rooms are comfortable and include a downstairs suite, offering a softer landing for travelers who want the soak without setting up a campsite.
The B&B has a relaxed, home-style character, down to details such as soft hand-ironed sheets. Breakfast arrangements have included a family-style meal served at a set morning time rather than an ordering-from-the-menu affair, so current details are worth confirming when making plans.
Pets are welcome on the property, and dogs are a familiar sight on campground walks. Between the river, lawns and walking areas, the grounds give people and their four-legged companions room to stretch out.
The useful, unvarnished details
The changing area, bathrooms and showers are basic, which suits the campground character of the place. They are also not immediately beside the hot pool, so a visit can involve a short walk between facilities and the soaking area.
That practical simplicity is balanced by well-kept grounds, clean pools and the unusual pleasure of having a warm soak waiting a few steps from a river campsite. For a single night, it can turn a routine stop into a genuinely restful one. For several nights, it gives the surrounding outdoor country a comfortable home base.
