Sunbeam Hot Springs offers a unique blend of natural serenity and geothermal wonder tucked away in the heart of Idaho’s rugged wilderness. 

Sunbeam Hot Springs took me by surprise during my first visit to Idaho! This hidden gem is nestled along the banks of the Salmon River, and to my surprise, it’s HOT.

In fact, it is one of the best Idaho hot springs I’ve ever been to!

And it gets better: as of 2023, it became the new Boat Box Hot Springs, so now you have more ways to enjoy Sunbeam. I’ll explain more in this post. 

Below, we’ll dive into everything you need to know about visiting Sunbeam, including how to get there and what to expect when you arrive.

Getting to Sunbeam Hot Springs

Sunbeam Hot Springs is conveniently accessible, located about 13 miles east of Stanley, Idaho, along State Highway 75.

To reach the hot springs, you can take a scenic drive along the highway, which runs through the heart of the Sawtooth National Recreation Area, offering stunning views of Idaho’s rugged landscape.

The springs are situated near the Sunbeam Dam site, and there’s a parking area provided right off the highway.

From the parking lot, it’s just a short and easy walk to the hot springs themselves via a dirt path (pictured below).

Soaking

Once you arrive at Sunbeam, you’ll notice the changing room and bathroom right on the lot. From there, you’ll take a short path down to the Salmon River where the main tubs sit.

Tub & Boat Box Cauldron

The photo above shows the cauldron that has been MOVED to Sunbeam!

From my experience, the blue tub AND new Boat Box cauldron are where the best soaking experience is. Both tubs have a direct line connecting them to the hot water source.

Please make sure you test the water before going in! You can quickly burn yourself.

You’ll want to regulate the temperature by using the buckets provided to dump snow or Salmon River water into the tubs.

Rock Pools

There are rock pools closer to the base of the river you can soak in, but I don’t recommend these. Truthfully, the rocky, sandy bottom of the pools can be unenjoyable.

If the tubs are full, I’d wait to enter them since only about 3 people max and fit inside at a time.

When to Go

The best time to enjoy Sunbeam Hot Springs would be fall and winter when the weather is cooler. Sunbeam Hot Springs is open throughout the year, including summer.

However, summer can be a bit less enjoyable because it’ll be warm outside! 

Where to Stay

During my last visit to Idaho, Scott and I stayed in Triangle C Cabins and LOVED our time there.

These are the perfect cabins to enjoy a relaxing getaway in Stanley, Idaho, and relatively close to Sunbeam!

Quick History of Sunbeam Hot Springs

Sunbeam Hot Springs has a rich history intertwined with Idaho’s natural and cultural landscape. Its story begins with the native tribes who first discovered and utilized these thermal waters. 

These indigenous peoples revered the hot springs for their healing properties and as sacred sites for centuries.

In the late 19th and early 20th centuries, Sunbeam Hot Springs became a notable stopover for miners and travelers as settlers moved westward. 

The name “Sunbeam” itself is said to have originated from the way sunlight dances across the water’s surface, creating a shimmering effect that captured the imagination of those who visited. 

Now managed by the U.S. Forest Service, it has been preserved as a public natural resource, allowing visitors to continue enjoying its therapeutic benefits.
