There’s a particular kind of quiet that settles over a hike-in hot spring once the trailhead crowd thins out and the last mile of switchbacks is behind you — steam curling off a granite-lined pool, no parking lot in sight, just the sound of water finding its way downhill. Hike-in hot springs reward the kind of traveler who’s willing to trade convenience for solitude, and as snowmelt clears high-country trails through late spring and summer, this is peak season to go find one. Whether you’re chasing a single-night out-and-back or building a multi-day loop around a soak, the backcountry hot springs scattered across the Rockies, the Pacific Northwest, and the desert Southwest offer some of the most memorable soaking experiences in the country — you just have to earn them.
This guide walks through some of the best hike-in hot springs in the US, organized by region, along with what you actually need to know before you load up a pack and head for the trailhead. As always, we’re keeping the specifics — the exact mileage, the precise temperatures, the turn-by-turn directions — inside the Soakr app, where they belong. Out here, we’re setting the scene.
Why Hike-In Hot Springs Are Worth the Effort
Roadside hot springs have their place — they’re easy, they’re social, and they’re a great entry point if you’re new to soaking culture. But hike-in springs are a different experience entirely. The approach itself becomes part of the ritual: you’re moving through alpine meadows, river canyons, or old-growth forest, and by the time you reach the pool, your body has already shifted into a slower gear. There’s a psychological reset that happens on a trail that doesn’t happen in a parking lot.
Hike-in springs also tend to be smaller, more intimate, and dramatically less crowded than their drive-up counterparts, especially on weekdays or if you’re willing to start early. Many sit in genuinely wild settings — river canyons, subalpine basins, old-growth forest — that you simply can’t access any other way. And because they require effort to reach, they tend to attract a soaking crowd that respects the space: quieter, more conservation-minded, more likely to pack out what they packed in.
The tradeoff is real, though. Hike-in springs demand more planning, more physical readiness, and more respect for changing conditions — weather, trail washouts, and seasonal water levels can all affect access. That’s exactly why this guide exists: to help you find the right hike-in hot spring for your trip and go in prepared.
Best Hike-In Hot Springs by Region
Rocky Mountains: Colorado, Wyoming, and Montana
The Rockies hold some of the most celebrated backcountry soaks in the country, many of them tucked into wilderness areas that require a real climb to reach.
Conundrum Hot Springs, high in the Maroon Bells–Snowmass Wilderness outside Aspen, might be the single most famous hike-in hot spring in Colorado. The approach climbs steadily through aspen groves and past waterfalls before opening into a high alpine basin, where a series of pools sit with sweeping views of the surrounding peaks. It’s popular enough that overnight permits are required during peak season — plan ahead rather than showing up and hoping for a spot.
Jerry Johnson Hot Springs, just across the Montana–Idaho border along the Lochsa River corridor, offers a shorter, gentler approach through dense forest to a string of pools terraced along a small creek. It’s an easy add-on to a road trip through the Bitterroot range and makes a great first backcountry soak if you’re new to hiking for your hot springs.
Near Yellowstone, Boiling River and the more remote Huckleberry Hot Springs both reward hikers willing to walk in rather than drive to a trailhead lot. Boiling River sits where a hot tributary meets the Gardner River, creating a natural mixing zone of warm and cold water you can dial in yourself by choosing your spot. Huckleberry, farther off the beaten path near Grand Teton, has a wilder, more secluded feel and rewards those willing to seek it out.

Pacific Northwest: Idaho, Oregon, and Washington
Few regions in the country pack in as many hike-in hot springs as the Pacific Northwest, where volcanic geology and dense national forest combine to hide dozens of soaking spots along creeks and rivers.
Goldbug Hot Springs in Idaho’s Salmon River Mountains is often cited as one of the most beautiful hot springs in America, and it’s easy to see why once you’ve made the climb. A cascading series of pools tumbles down a mountainside, each one offering a different temperature and a different angle on the surrounding peaks. It’s become popular enough in recent years that arriving early — or visiting on a weekday — makes a real difference in how much of the canyon you’ll have to yourself.
In Oregon, Terwilliger Hot Springs (also known locally by another name) sits in a forested canyon along Cougar Reservoir, with a short, well-traveled path leading to a series of terraced stone pools shaded by old-growth trees. Nearby, Umpqua Hot Springs perches on a bluff above the North Umpqua River, its travertine-rimmed pools offering one of the most photogenic soaking settings in the state — especially with morning fog rising off the canyon below.
Washington’s Olympic Hot Springs, inside Olympic National Park, and the more remote Goldmyer Hot Springs in the Cascades both require a genuine hike through temperate rainforest, rewarding visitors with pools that feel worlds away from the coastal towns just a couple hours south.

Southwest and California
The desert Southwest and California’s mountain ranges hold their own set of worthwhile hike-in springs, often with a very different character from the alpine soaks farther north.
Deep Creek Hot Springs, tucked into a canyon along the Pacific Crest Trail in Southern California, is one of the most accessible backcountry soaks near a major metro area — which also means it draws a crowd on weekends. The canyon setting, with the creek running past a series of rock-lined pools, makes the approach worth it even with company. Go early or go on a weekday if solitude is the goal.
In Utah, Fifth Water Hot Springs near Spanish Fork Canyon has become a favorite for a reason: a forested trail follows a creek past small waterfalls before opening onto a series of turquoise, mineral-rimmed pools that look almost otherworldly. It’s become one of the most photographed hot springs in the state, so timing your visit for early morning or a weekday afternoon goes a long way toward having the pools to yourself.

What to Know Before You Hike In
Hiking to a hot spring is a different undertaking than driving to one, and a little preparation goes a long way toward making the trip smooth rather than stressful.
Timing Your Trip
Late spring through summer is prime season for most hike-in springs, especially the higher-elevation ones in Colorado, Wyoming, and Montana, where snowpack can block trail access well into the season. Lower-elevation springs in Oregon, Idaho, and California often open up earlier and stay accessible longer into fall. Whatever spring you’re targeting, check current trail conditions before you go — snowmelt, spring runoff, and seasonal creek crossings can all affect whether a trail is passable, and conditions can shift week to week. Our guide on the best time to visit hot springs breaks down seasonal patterns in more depth if you’re planning around a specific window.
Morning and weekday visits are your best bet for having a popular hike-in spring mostly to yourself — the more well-known spots on this list have all seen a surge in foot traffic in recent years, and arriving with the first light beats arriving with a Saturday afternoon crowd.
Permits and Regulations
Some hike-in hot springs, particularly those inside wilderness areas or national parks, require permits for overnight camping nearby, and a few limit daily visitor numbers during peak season. Regulations vary significantly by land management agency — some are Forest Service trails, others fall under National Park Service or BLM jurisdiction — so it’s worth confirming requirements for your specific destination well before you head out. Trailhead parking can also fill up fast at popular access points during summer weekends, so build in a buffer if you’re not an early starter.
What to Pack
A hike-in soak means carrying everything you need for both the trail and the pool. Beyond standard hiking essentials — layers, plenty of water, a map or offline navigation, and sun protection — plan for the temperature swing between trail and water: a lightweight pair of sandals for wet rocks around the pool, a quick-dry towel, and a dry bag to keep your post-soak clothes protected are all worth the extra ounces. If your route includes an overnight, treat it like any backcountry camping trip, with appropriate food storage and Leave No Trace practices in mind. Our full hot springs packing list covers gear recommendations in detail, and if you’re pairing your soak with a night under the stars, the hot springs camping guide walks through how to plan the combination trip.
Trail and Pool Etiquette
Hike-in springs tend to have a stronger etiquette culture than their roadside counterparts, partly because the people willing to make the hike tend to care more about preserving the experience. Pack out everything you bring in, including trash left by others if you’re able. Keep glass containers out of the equation entirely — a shattered bottle in a remote soaking pool is a hazard nobody wants to deal with miles from a trailhead. Give other soakers space, keep noise to a respectful level, and be mindful that clothing norms vary spring to spring — when in doubt, follow the lead of whoever’s already there. Our hot springs etiquette guide covers the full set of best practices if you want the complete rundown before your trip.
Safety Considerations
Backcountry hot springs come with a different risk profile than a developed resort. Trail conditions can change fast — a creek crossing that was manageable in June might be a different story after a storm, and afternoon thunderstorms are common in the high country through summer. Cell service is unreliable to nonexistent at most of these locations, so let someone know your route and expected return time before you head out, and carry a paper map or downloaded offline route as backup. Water temperatures in natural pools can also vary significantly from one pocket to another, so ease in rather than jumping straight to the hottest spot. For a full breakdown of backcountry-specific safety considerations, our hot springs safety guide is worth a read before you commit to a trail.
Building Your Hike-In Soaking Trip
If you’re new to backcountry hot springs, start with a shorter, well-traveled approach — something like Jerry Johnson or Terwilliger — before committing to a longer climb like Conundrum or Goldbug. Once you’ve got a feel for what a hike-in soak involves, the payoff scales with the effort: the more remote the spring, the more likely you are to have it to yourself, and the more the surrounding landscape becomes part of the experience rather than a backdrop to it.
Many of these regions cluster multiple hike-in springs within a few hours of each other, which makes for a natural multi-day trip if you’re willing to string a few trailheads together. A loop through Idaho’s Salmon River country, for instance, can combine Goldbug with several nearby soaks in a single trip, while a Colorado itinerary built around the Maroon Bells–Snowmass Wilderness can pair Conundrum with other high-country trails in the area.
Whatever route you choose, the goal is the same: a pool that feels earned, in a setting most people never see, at the end of a trail that did some of the work of relaxing you before you even got there.
