Quinn's Hot Springs, Montana: Pools and Day Passes

What Quinn's Hot Springs Resort is

The resort occupies a stretch of the Clark Fork River in far western Montana, with the pools set against the backdrop of the Bitterroot Mountains. The water is naturally heated and classed as a silica spring, with sodium and sulfate among its other dissolved minerals, and the setting is landscaped rather than wild.

Because everything sits on one property, a visit here is a single-destination trip: soak, eat, sleep and repeat. That is the main trade-off against Montana's hike-in soaks, where you earn a quieter pool but give up the bed and the kitchen.

Getting there from Missoula

Paradise is roughly a 1.5-hour drive northwest of Missoula. From Missoula, take I-90 west to St. Regis, then follow MT-135 north to the resort, a route that trades interstate speed for a slower river valley drive on the second leg.

Plan the drive as a half-day each way if you are coming from Missoula for a day-use session, since the return leg puts you back on I-90 in the evening. Staying overnight removes that pressure and lets you use the quietest parts of the day at the pools.

The pools and how hot they run

The resort's current pool information page describes seven pools: five natural, flow-through hot springs pools and two salt-treated pools. The natural pools run 100°F to 106°F alongside a 55°F cold plunge, and the salt-treated pools stay at about 97°F to 100°F, so you can move from a warm social pool to a genuinely hot soak and back again.

Layout matters more than pool count here. Some pools are larger and busier and work well for groups, while others are more secluded and quieter, so pick your spot by mood rather than by temperature alone.

Treat the hottest water as a short dip and keep your head above the surface in natural geothermal water. The rock and pool decks get slick, so walk rather than stride between pools.

Each pool carries its own age rule, which shapes who ends up where. Pool 1 is adults only. Pools 2 through 4 admit ages 14 and up. Pool 5 is for ages 5 and up who are toilet trained, Pool 7 admits ages 3 and up who are toilet trained, and Pool 6 is open to all ages, with swim diapers and waterproof pants required for children who are not toilet trained. Children under 5 may not enter water above 100°F.

For a mixed-age family, that means the salt-treated pools and the cooler natural pool become the home base, while adults rotate into the hotter, older-guest pools in shifts. Toys and floats are allowed only in Pools 6 and 7, and balls and throwing are prohibited everywhere.

Water enters from a geothermal well at 118°F and is blended with cold water to hit each pool's target temperature, then returns to the aquifer at about 40°F. Staff test the pH daily and post it, and the resort notes that the water can irritate skin, so rinse off after your last soak.

Day-use sessions versus staying overnight

Pool access is included for overnight guests with no separate booking, while visitors who are not staying on site reserve a timed day-use swim session online ahead of their visit. That makes the decision straightforward: if you plan to soak twice in a day, or once at each end of it, an overnight stay starts to make more sense than a single session.

Sessions are a fixed length, so the practical question is which block fits your drive. Morning blocks suit an early start from Missoula, and the evening block lets you arrive after a day of sightseeing. Weekends and peak summer weeks are when reserving early matters most.

The reservation rules are laid out below, and the resort's swim session terms and conditions cover the details of payment and changes.

How day-use sessions work

Day visitors choose one of three four-hour blocks: 8 a.m. to noon, noon to 4 p.m., and 4 p.m. to 8 p.m. You can arrive at any point inside your block, but you must be out of the pools by its end time, and the resort asks you to arrive about 15 minutes early to check in, shower and change.

The cancellation line is 10 p.m. three days before the session, and the full amount is charged to the card on file at that same deadline. Cancel or reschedule before then and the booking can be refunded or moved; after it, or if you simply do not show up, the payment is non-refundable and cannot be transferred to a new date.

Bring your own towel, because day-use guests are not provided one, and pool towels and swimwear are sold at Fannie's Gift Shop on site. Changing rooms have walk-in showers, and swim bands give access to a locker.

Cabins, riverside rooms and the Glacier Lodge

Lodging ranges from rustic cabins with private porches and wood-burning stoves to rooms in the Glacier Lodge, which comes with modern comforts and, in some rooms, balconies overlooking the river. The resort counts two lodges and more than 25 canyon and river-side cabins, and riverside cabins put the sound of the Clark Fork outside your door, a real upgrade if you plan to leave the window open.

Dogs are limited to specific cabins: some of the Canyon Cabins on the mountainside and the Meriwether Lewis and William Clark cabins on the riverside. Note the pet when you book, since a pet fee is added to the reservation balance. Lodge rooms suit anyone who would rather skip the wood stove and the porch. Animals other than service animals are not allowed in the pool area.

Check-in, pool hours for lodging guests and camping

Check-in is at 4 p.m. and check-out is at 11 a.m. for all accommodations, but overnight guests can start soaking at 2 p.m. on arrival day and keep soaking until 1 p.m. on departure day. Keys are guaranteed until 11 p.m. on your arrival date, so call the front desk if you will be later than that.

Lodging guests have the longest pool window: 7 a.m. to 11 p.m., with the first hour (7 to 8 a.m.) and last hour (10 to 11 p.m.) reserved for adults. Guests under 18 swim from 8 a.m. to 10 p.m. with adult supervision. Those adults-only bookends are the quietest water on the property.

The resort no longer has RV sites. Tent campers are pointed to Cascade Campground, about three miles away, and barbecues and campfires are not permitted on the resort grounds. Outside food and drink are also not allowed anywhere on the property, so plan to eat at the on-site restaurants.

Eating at the resort

Several venues cover the day: Harwood House Restaurant for western-inspired dining built around locally sourced steaks, seafood and organic produce, with a Wine Spectator-recognized wine list; Quinn's Tavern for casual pub food, tap beer and cocktails; and a poolside bar with espresso for between-soak drinks. You do not need to drive anywhere after a soak.

Reserve a table at Harwood House for weekend dinners, since dinner reservations are highly recommended, and book lodging and dining together well ahead during peak season. That is the single most useful planning step for a summer visit.

Best time to go

The resort runs year-round, and the seasons change the character of the soak more than the water does. Summer brings river rafting, fly fishing for trout and guided trips on the Clark Fork, while winter quiets the property down and pairs the pools with cross-country skiing and snowshoeing nearby.

Early morning and late evening give you the most peaceful water, whether that means dawn in July or dusk in January. If you are day-tripping, aim your pass window at one of those ends of the day.

The resort closes for about a week each spring for cleaning projects, so build any shoulder-season trip around that gap. Outside it, the pools run most days of the year.

Safety, conduct and accessibility at the pools

There is no lifeguard. Children under 14 and non-swimmers need an adult with them at all times, and children 5 and under must stay within arm's reach. The resort recommends limiting each soak to 15 minutes to avoid dizziness, fainting or nausea, and advises anyone who is pregnant or has heart disease, diabetes or high blood pressure to talk with a doctor first. Anyone with a waterborne illness should stay out of the water.

Conduct rules are stricter than at a backcountry pool. Shower before you enter, use the stairs and handrails, and do not dive, jump, run or climb on the rocks and dividing walls. Glass is banned in the pool area, intoxicated guests should not use the pools, and smoking, vaping and nicotine pouches are not allowed. Bluetooth speakers are prohibited, so bring earbuds if you want music. Food and drinks bought on site may be taken to a designated area, and empty water bottles can be filled at a station in the changing-room building.

For accessibility, the resort has a pool lift with staff on hand to help, an elevator from the ground floor up to the pool deck, a ramp to the pool check-in desk, and a family-friendly accessible changing room and restroom.

Nearby springs to combine on a road trip

Quinn's sits in a corridor of western Montana soaks, which makes it a natural base for a multi-stop trip rather than a single overnight. Loop in other hot springs in Montana across the Bitterroot Valley and the Jefferson Valley, then push south if your route allows.

For contrast on the same trip, Lost Trail Hot Springs in the Bitterroot Valley and Renova Hot Springs in the Jefferson Valley give you a different scale of stop, and Bozeman Hot Springs anchors an eastern leg if you are building a longer loop.

Yellowstone Hot Springs, Montana, near Corwin Springs, is another developed stop worth folding into a wider Montana itinerary if you are heading toward the park.

What to bring for a resort soak

Pack a proper swimsuit, a towel and sandals for the pool decks, plus a dry layer for the walk back to your cabin in cool months. Bring an empty water bottle to fill at the changing-room station, since hot soaking dehydrates you faster than you expect.

Leave glassware behind, since glass is not allowed in the pool area, and keep valuables in your room or locker rather than on a lounger. A small bag you can carry between pools keeps the logistics simple.

For anything else about access, food service or lodging, contact Quinn's Hot Springs Resort directly before your trip.

Plan Your Visit

Quinn's rewards a plan: pick your pool by temperature and age rule, decide between a reserved day-use session and a riverside cabin, and time the drive from Missoula so you arrive at the quiet end of the day. Book lodging and dinner together for weekends and summer.

If you want the developed-resort version of a Montana soak with the Clark Fork outside your window, this is the stop. If you want a primitive pool you hike into, build that into a separate leg and use the state guide to choose it.
