Before we dive into the deets, let’s refresh with a little hot springs etiquette! Please read this portion–it’s vital to keeping these loved hot springs safe, clean, and enjoyable for all who visit, and respectful to the locals who built this spot for you to enjoy.

What To Pack for a Hot Springs Adventure

Nomadix microfiber towel

Nomadix’s microfiber towel kept dried me off fast!

  • WATER and lots of it. Hot springs are dehydrating! I always carry a 32-oz water bottle and finish the entire thing by the end of my soak. Consider bringing a little extra punch with an electrolyte powder to make sure you’re staying well hydrated!

  • A microfiber towel. These are lightweight and quick drying and work great for a quick dry-off before throwing your clothes back on. This is the epic national parks towel I LOVE.

  • A z-mat or some other waterproof surface to lay your belongings while soaking.

  • A trash bag for your trash along with others' trash you find along the way. Help keep these places clean and pristine!

  • Waterproof sandals. I picked up a pair of these rubber knock-off Birkenstocks from Amazon. Highly recommend.

  • Hiking boots for longer walks. I basically live in my Danner Mountain 600s.

  • Clothes to change into. Making the trip home wet is no bueno. Make sure you have something dry to wear post soak for peak comfort.

How do You Get to Boat Box Hot Springs?

Boat Box is right off the highway on the Salmon River, which was honestly a bit of a surprise for me. From the pictures I’d seen, I’d imagined it being tucked away in a remote part of Idaho’s forests, but it’s so close to Highway 75 that you could potentially splash a car driving by.

From Stanley, drive 3.3 miles along the Hwy 75 and park on its wide shoulder. If you see steam, you’re in the right place!

Boat Box is tiny, with space for no more than two people. Because of its popularity and small capacity, you may stumble upon others and will need to wait your turn. Give them space and let them enjoy a peaceful soak–I’m sure you’d appreciate the same!

There are a few smaller pools just north of Boat Box along the river, corralled by rocks to keep the heat in. This is a great option if you’d rather not sit and wait in your car! Make sure to ask those already in Boat Box if they’d mind you enjoying those pools before hopping in.

Pro tip: If Boat Box is looking a little dirty, open up the valve at the base of the pool to drain it, then use the PVC pipe to refill the tub. Note: It’s HOT! If it’s too hot, use the provided bucket to add a little river water–works like a charm.
