Nat Soo Pah Hot Springs

Nat Soo Pah Hot Springs & Campground is a family owned hot springs resort in the high desert farmland south of Twin Falls. It is an old fashioned summer soak: a very large geothermal swimming pool with a waterslide and diving boards, a hotter soaking pool, a hydro jet tub, and a grassy RV park and campground wrapped around it all. The name is Shoshone for “Magic Mineral Water,” and the resort has been drawing swimmers since the main pool was built around 1926.

Plan around the season. The pool opens May 1 and closes after Labor Day, and the campground stays open into mid-October. Outside that window the pools are closed for the winter, which is the normal rhythm here, so time your visit for late spring through early fall.

Location, Map & Directions

From Twin Falls, drive south on US Highway 93 for about 16 miles. The resort sits in the farmland south of town, roughly 3.5 miles east of the small community of Hollister, at 2738 E 2400 N. The grounds are grassy and shaded with mature trees, with picnic areas spread around the pool complex, a setting that feels more like a country swim club than a desert outpost.

The Soaking Experience

The main swimming pool is the centerpiece: 125 feet by 50 feet of naturally heated water, fed by a spring that surfaces at about 99°F. A 90 foot waterslide drops into the pool, and two diving boards sit on different sides of it. Certified lifeguards are on duty, per the resort’s own site, which makes this one of the easier Idaho hot springs to enjoy with kids.

When you want it properly hot, move to the Hot Soak Pool, kept at 104 to 106°F. A reverse freon system boosts it above the source temperature, so it stays a true soaker’s pool even though the spring itself runs cooler. The hydro jet hot tub sits at about 100°F. The swimming pool and soak pool are treated with chlorine, and swimwear is required throughout the pool area.

Fees, Hours & Reservations

The resort does not publish its admission or camping rates online, and its exact pool hours appear to vary across the season, so call 208-655-4337 before you go for current prices and hours. What is fixed is the season: the pool runs May 1 to Labor Day, and camping continues into mid-October (the resort’s site lists camping open through October 15). Camping reservations are accepted and recommended, especially for the full hookup sites on summer weekends.

Facilities, Lodging & Nearby

There is no hotel or cabins here; staying the night means camping, and the camping is a big part of the draw. The grounds hold 75 campsites, all grass, including 29 full hookup RV sites and about 30 pull through sites, plus tent sites, a dump station, showers, and modern restrooms.

Camping

Campers get the run of the resort amenities: a snack bar and concession stand, an arcade room, picnic tables and pavilions, fire rings, horseshoe pits, and a playground. WiFi is available at the campground, and pets are welcome at your site, just not in the pool area. The resort also hosts reunions, birthday parties, company events, and church groups, so summer weekends can feel lively.

History

“Nat Soo Pah” is a Shoshone name meaning “Magic Mineral Water.” Shoshone people living in the nearby foothills used the spring for baths long before settlement. Early settlers built separate bathhouses for men and women, and the main pool was built in approximately 1926. A century on, it remains family owned and proudly old fashioned, a summer resort run much the way it always has been.

Safety & Health

The Hot Soak Pool runs 104 to 106°F, which is genuinely hot: limit your soaks, get out if you feel dizzy, and test the water before you settle in. Certified lifeguards staff the main pool, but children should still be supervised around the waterslide and diving boards, as at any swimming pool.

Best Time to Visit

The pool season, May 1 to Labor Day, is the whole show. Early season visits in May and June tend to be quieter, while July and August bring the full summer crowd of swimmers and campers. If you are camping rather than swimming, the season stretches into mid-October, though the pools close after Labor Day.

Make it a Magic Valley soak loop: Miracle Hot Springs, near Buhl and Hagerman about 40 minutes northwest, pairs big general pools with private soaking pools, and its sister property Banbury Hot Springs sits just down the road from it. More South-Central Idaho hot springs →
