Prince Albert Hot Spring in Idaho is a primitive mountain hot spring with some of the best views in the state. Located about 76 miles northwest of Twin Falls, it sits high above the small town of Glenns Ferry. This site is one of those wild Idaho hot springs you hear about — no amenities, no crowds — just quiet mountain air and hot mineral water.

The spring is far from any town, making it a true escape for anyone craving a break from the highway. If you are looking for adventure, this is it—but reaching it requires effort.

You will start on paved roads for most of the drive, but the final stretch turns into rough dirt tracks that climb steep hills. If you are in an RV or a 2WD vehicle, it is best to park at the BLM gate, approximately 1.5 miles from the spring, where public land begins. From there, hike the rest of the way.

A high-clearance 4WD might get you closer, but the road becomes steep, rutted, and rocky. Only experienced drivers should attempt it—and never when it is wet or snowy. Tires can dig ruts, and you risk getting stuck. Our Subaru Crosstrek handled most of the road, but we stopped about half a mile from the top and hiked the rest.

The spring is the only water source around, so it draws insects—especially Mormon crickets—and sometimes snakes. Stay aware and wear boots. It can get very hot on sunny days, so be sure to bring extra water and sunscreen.

The payoff? Sweeping views of rolling hills, big skies, and the Snake River Valley stretched out below. And surprisingly, even here, you’re likely to have cell service (T-Mobile, AT&T, and Verizon).

Prince Albert Hot Spring Experience

Hot mineral water emerges from the hillside at 130°F. By the time it reaches the soaking tubs, it cools to a comfortable 100–104°F. You might notice a slight sulfur smell, but it’s milder than at many other Idaho hot springs.

The upper pool is built from stone and cement, cleverly damming the flow to form a roomy soaking area. It comfortably fits up to five people. Farther down the hill, smaller stone-lined pools accommodate two to four people each.

Locals have installed PVC pipes to help filter the water and drain the tubs. If a pool is full of insects, leaves, or debris, you can use the pipes to drain and refill it with fresh water from the source. It is simple — and it works.

The area around Prince Albert Hot Spring is just as wild as the spring itself. If you’re into adventure, you’ll have plenty to do:

• Hiking: The walk up from the gate is steep but rewards you with amazing views and solitude.
• Camping: Primitive camping is possible right by the spring. There’s a small fire ring but no bathrooms or trash cans.
• Star Gazing: With no city lights around, the night sky is incredible.
