Nat-Soo-Pah: Hot Water in the High Desert
After the long climb out of Ely and the long drop down the Snake River country, there is a sign on the road south of Twin Falls, Idaho, that promises exactly what a rig-weary traveler needs: hot springs. Nat-Soo-Pah (say it NAT-soo-pah; you will get the hang of it by the second evening) is a hot springs resort and RV park in the sagebrush south of town, and it is the kind of place that turns a fuel-and-groceries overnight into a three-night stay.
Hot Water in the Desert
The springs here are the real thing - geothermal water rising from deep in the Snake River Plain, one of the most volcanically active-looking landscapes in America even when it is quietly growing famous potatoes. The main pool is fed by a spring running right around ninety-nine degrees, warm enough to soak in for hours, cool enough to stay for a whole afternoon. There is a large swimming pool, a hotter soaking pool for the serious soakers, and - the kids-and-grandkids vote-winner - a water slide.
We came in with the plan of one night: laundry, a town run, north toward the mountains the next morning. Then we got in the pool at sunset, steam coming off the water with the first stars overhead, and by nine we had booked a second night. The desert south of Twin Falls is wide open and quiet; the park's grass and trees feel like an oasis in exactly the way the brochures promise and few places deliver.
Base Camp for the Twin Falls Country
The park sits handy to some of southern Idaho's best sights. Twin Falls itself - the town and the waterfall alike - is an easy drive north: the Snake River canyon, Perrine Bridge and the BASE jumpers who float off it, Shoshone Falls, which the locals will correctly tell you drops higher than Niagara. And the city's groceries, farm stands, and restaurants make resupply easy; this is one of the best-provisioned base camps on the whole northern route.
South and west, the volcanic country stretches toward the Craters of the Moon and the silent lava fields, and east lie the reservoirs and fishing water of the Snake. For us the park was the door into Idaho - the first long stop in the state, and the place we finally shook off the Nevada dust.
Soaking Notes
A few tips. The pools have hours and the soaking pool runs hot - respect the heat and hydrate like it is a job. Sites are level-ish gravel with hookups and the park welcomes big rigs; the interior roads are fine but take the turn in slow. Weekends fill with local families, so if you want the quiet desert feel, aim for a weekday. And do not leave without at least one after-dark soak: the sky out here is dark, the water is warm, and the combination is unbeatable.
Sometimes the memory of a stop is the scenery; sometimes it is the history. And sometimes - this is one of those - it is the simple luxury of hot water and nowhere to be in the morning.
