There’s a particular kind of trip where the destination isn’t a city or a landmark — it’s a string of steaming pools scattered across mountain valleys, desert basins, and river canyons. A hot springs road trip turns the drive itself into the point: long stretches of highway broken up by the ritual of finding a spring, easing into it, and watching the landscape change from the water’s edge. Whether you’ve got a long weekend or two full weeks, the US has enough geothermal terrain to build a genuinely unforgettable itinerary, and the trick isn’t finding springs — it’s stringing the right ones together so the driving, the soaking, and the scenery all pull in the same direction.
This guide breaks the country into four regional loops, each built around a cluster of springs that make sense to visit together. You don’t need to do all four. Pick the one that matches your season, your vehicle, and your appetite for hiking, and treat the rest as a life list for future trips.
How to Think About Planning a Hot Springs Road Trip
Before you start plotting pins on a map, it helps to think in terms of clusters rather than a straight line from A to B. The best hot springs road trip itineraries loop through a region where several springs sit within a few hours of each other, rather than trying to connect springs that happen to be in the same state but are actually a full day’s drive apart. Idaho alone has springs scattered across nearly the entire state — trying to hit the panhandle and the southern desert in one trip is a mistake most first-timers make once.
Mix your spring types on any given loop. A trip built entirely around backcountry hikes will burn you out; a trip built entirely around commercial resorts will feel like you never left civilization. The loops below intentionally braid together primitive, developed, and commercial springs so you get variety in access, crowd level, and vibe from one stop to the next.
Season matters more for a hot springs road trip than almost any other kind of travel. Alpine and high-elevation springs are often snowed in or river-swollen well into early summer, while desert springs in places like Nevada and California are brutal to reach in peak summer heat and far more pleasant in shoulder season. Build your route around what’s actually accessible when you’re going, not just what looks good on a map.
Finally, don’t try to freelance your directions from a blog post. Springs move in and out of accessibility as roads wash out, land management changes, or water flow shifts — the Soakr app keeps this information current with GPS directions and community-reported conditions, which is a lot more reliable than a road trip plan built on stale driving directions.
The Pacific Northwest Loop: Oregon and Washington
The Pacific Northwest loop is a forest-and-river trip, built around the Cascades corridor running from central Oregon up into Washington. It’s a good pick for travelers who want lush, green scenery and don’t mind a little rain.
Terwilliger Hot Springs
Also known locally by an older nickname, Terwilliger sits in a forested canyon along a tributary of the McKenzie River, with a series of rock-lined pools stepping down the hillside beneath a canopy of old-growth trees. It’s one of the most photographed springs in the Cascades for good reason — the pools themselves feel sculpted by hand even though they’re entirely natural.
Bagby Hot Springs
Bagby is famous for its hollowed-log soaking tubs, a piece of rustic infrastructure that’s been part of the experience here for generations. The setting — deep in the Mount Hood National Forest, reached by a walk through mossy old-growth — makes this one of the most atmospheric soaks in the state.

Olympic Hot Springs
Crossing into Washington, Olympic Hot Springs sits inside Olympic National Park, tucked into a valley that requires a genuine walk to reach. The reward is a handful of small, mineral-tinted pools surrounded by dense rainforest — one of the few national park soaks left that hasn’t been developed into something more formal.
For a deeper dive into this corner of the country, the Best Hot Springs in Oregon guide covers the full Cascades lineup, and if you’re routing through the Seattle metro on your way north, Hot Springs Near Seattle has day-trip options worth folding into the same drive.
The Northern Rockies Loop: Idaho, Wyoming, and Montana
This is the classic American hot springs road trip — the loop most soakers dream about, running through the mountain heart of Idaho, up into the geothermal wonderland around Yellowstone, and across into Montana. Give this one the most time if you can; it rewards a slower pace.
Kirkham Hot Springs
Set right along the Payette River in the Sawtooth National Forest, Kirkham is about as scenic as roadside springs get — a series of pools and even a small waterfall-fed soak, with the river rushing past just feet away. It’s an easy introduction to Idaho’s spring culture without demanding a serious hike.
Goldbug Hot Springs
Tucked into the Salmon River Mountains, Goldbug rewards hikers with a cascade of pools tumbling down a mountainside, each offering a different temperature and a different angle on the surrounding peaks. Many longtime soakers consider it the most beautiful hot spring in the country, and once you’ve seen the view from the upper pools, it’s hard to argue.

Boiling River
Just inside Yellowstone National Park, Boiling River is where a genuinely scalding thermal runoff mixes with the cold Gardner River, creating a natural gradient of temperatures you can shift into and out of by moving a few feet in either direction. It’s one of the only legal soaking spots inside the park itself, which makes it a must for any Yellowstone-adjacent itinerary.
Granite Hot Springs
In Wyoming’s Bridger-Teton National Forest, Granite Hot Springs is a developed pool fed by a natural spring, set in a remote valley that feels worlds away from the crowds of the nearby Tetons. The drive in is part of the experience — a long, quiet forest road that slowly narrows the world down to just trees and mountains.
If Yellowstone is anchoring your route, Hot Springs Near Yellowstone rounds out the full list of soaks around the park, and 15 Best Hot Springs in Idaho is worth reading before you finalize which side trips fit your timeline.
The Colorado High Country Loop
Colorado’s hot springs cluster along the spine of the Rockies, which makes it one of the easiest states to build a tight, high-reward loop in. This route works especially well as a long weekend if you’re already based in Denver.
Strawberry Park Hot Springs
Near Steamboat Springs, Strawberry Park is Colorado’s most beloved developed spring — natural rock pools set into a forested hillside, with a relaxed evening atmosphere that regulars return for year after year. It’s the kind of place that anchors an entire trip on its own.
Mount Princeton Hot Springs
Set at the base of its namesake 14,000-foot peak, Mount Princeton pairs a resort-style soaking experience with a creek-side setting where natural hot water mixes directly into the cold mountain stream, letting you dial in your own temperature by moving along the bank.

Conundrum Hot Springs
For travelers who want to earn their soak, Conundrum sits high in the backcountry outside Aspen, reached only by a serious multi-mile hike through wilderness terrain. The payoff is a set of pools with a genuinely alpine backdrop — jagged peaks rising directly behind the steam.
Glenwood Hot Springs
To close the loop with something more accessible, Glenwood Hot Springs is a full commercial resort experience in the town of Glenwood Springs, ideal for a rest day between the more adventurous stops on this route.
Colorado’s full lineup — including a few springs that didn’t make this itinerary — is in 12 Best Hot Springs in Colorado, and if you’re coming from the Front Range, Hot Springs Near Denver has additional short-trip options to bolt onto either end of this loop.
The Desert Southwest Loop: California and Nevada
The desert loop trades alpine forest for wide-open basin-and-range country, and it’s the best pick for a cooler-season hot springs road trip when the mountain routes above are still buried in snow.
Travertine Hot Springs
Just outside Bridgeport, California, Travertine sits on a mineral terrace overlooking the Eastern Sierra, with several pools of varying size and a backdrop of snow-capped peaks that makes it one of the most photogenic desert springs anywhere. Sunrise and sunset here are genuinely spectacular.
Deep Creek Hot Springs
In the mountains above the Mojave, Deep Creek is a cluster of pools along a flowing creek, popular enough that it draws a real community atmosphere on weekends. It’s a good example of a spring where the social scene is as much a part of the draw as the water itself.

Spencer Hot Springs
Crossing into Nevada’s Great Basin, Spencer Hot Springs is classic high-desert soaking — open sky, distant mountain ranges, and a handful of primitive pools with essentially no infrastructure between you and the landscape. Nights here under a dark sky are part of the draw.
Wild Willy’s Hot Springs
Back on the California side near Mammoth Lakes, Wild Willy’s offers a boardwalk-accessed pool with sweeping views across the Long Valley Caldera — an easy, low-effort stop that pairs well with a Sierra-adjacent leg of the trip.
For the full regional picture, 12 Best Hot Springs in California and the Nevada springs cluster around Spencer are both worth building into your planning window before you commit to a final route.
Building Your Own Route
Once you’ve picked a loop — or decided to stitch pieces of two together — a few practical habits make the difference between a smooth trip and a frustrating one. Check seasonal access before you lock in dates; alpine routes can stay snowbound well past when lower-elevation trip reports suggest. Pack for both extremes, since a single day on a desert-to-mountain loop can swing from hot and dry to cold and wet. And build in slack — the best moments on a hot springs road trip are rarely the ones you planned, they’re the unplanned stop at a spring you hadn’t heard of because a fellow soaker mentioned it at your last pool.
If you’re camping between stops, our Hot Springs Camping Guide covers how to plan a soak-and-camp trip properly, and it’s worth reading Hot Springs Etiquette before you go — knowing the unwritten rules makes you a better guest at every stop on your route, especially at the more primitive, community-maintained springs where etiquette matters most.
For travelers weighing how far to push into backcountry territory versus staying near developed resorts, 25 Best Hot Springs in the US You Need to Visit is a good cross-country reference that spans every difficulty level, and 50 Free Hot Springs in the US is worth a look if budget is a factor in how you build your loop.
Plan It in the App, Not on a Printout
A hot springs road trip lives or dies on current, accurate information — road conditions change, water levels shift with the season, and a spring that was perfect last summer might be a mudpit this spring. Static blog posts and printed guides go stale. The Soakr app doesn’t.
The 40+ springs mentioned in this guide — and over 2,000 more across the US — are in the Soakr app. Get GPS directions, community check-ins, photos, temperature data, and offline maps for every stop on your route, updated by the people who soaked there last. Download Soakr free for iOS
