How To Get To Bonneville Hot Springs in Idaho (Epic Hidden Gem!)

Post Summary: Visiting Bonneville Hot Springs In Idaho

Nestled alongside Warm Springs Creek, is Bonneville Hot Springs.

It’s one of the lesser-known Idaho hot springs, probably because it’s not as plainly visible as other famous ones like Sunbeam, Boat Box, and Kirkham Hot Springs.

However, lesser-known doesn’t mean it’s any less beautiful! Quite the opposite actually.

Tell Me More About Bonneville Hot Springs…

Bonneville Hot Springs is located along Warm Springs Creek in Central Idaho, close to other springs like Pine Flats Hot Springs and Kirkham Hot Springs.

Bonneville Hot Springs is a collection of piping hot pools that cascade from the source into a series of several rock-walled pools that trail to the river’s edge.

There is also a private soak shack that was built with a cast iron tub inside, if you are looking for a bit more privacy.

Bonneville Hot Springs

Bonneville Hot Springs requires a very, very easy quarter-mile trail to the pools.

To make it even more convenient, you can camp at Bonneville Campground which connects to the trailhead. Campers have 24-hour access to the pools, while day guests are charged a $5 day-use fee to park in the parking lot.

What To Pack For An Idaho Hot Springs Trip

Slip-On/Off Shoes: Bonneville Hot Springs requires a short trail Pack and wear shoes you can easily slip on and off for minimal fussing and maximum soaking. Grab yourself a pair of Teva Universal sandals to wear in and out of the water, or our reader-favorite Ember Mocs for easy outdoor slippers in the winter!

Towel: Choose a lightweight & quick-dry towel that isn’t bulky or heavy. We prefer ones by Nomadix, but also love these stylish ones by Slowtide!

Water Bottle: Water is essential when soaking in hot springs! The temperature of the pools can potentially bring negative effects, so make sure to hydrate often.

Dry Bag: Bonneville Hot Springs has several pools connected by rock walls. Pack a dry bag to stow away your important items like keys, cell phones, and cameras. You can also bring a big canvas tote, to hold bulky items like towels and coats, but keep it away from the water.

Snacks: Bring easy-to-eat snacks to keep up your energy when soaking. Remember to pack out all your trash, including orange peels and apple cores!

Coming in the winter? Bring microspikes, a big parka, and a trash bag (or a big dry bag!) to stuff everything in to keep it from getting wet on the snowy ground.

When Is The Best Time To Visit Bonneville Hot Springs?

Bonneville Hot Springs is open May-September.

The hot springs are essentially closed along with the closure of the campground. The access road is not maintained in the winter season.

Personally, we think late summer and early fall are the best times to visit Bonneville Hot Springs.

This is when the temperature can drop pretty low in the evenings, making your hot dips even cozier!

Regardless of the season, weather, storms, and snowpack (if coming early spring) can affect road safety, so it’s important to always check road conditions and the forecast before you head out. Click here to stay updated on the most current road conditions.

Enjoying Bonneville Hot Spring

This Idaho refuge hosts two unique pool areas, each with their own cool features! Below, we’re breaking down the pools so you can decide which one is best for you.

The Creekside Pools

Similar to Sunbeam Hot Springs, the hot water runs off of the cliffside, briefly cooling it before it pools in the creek below.

There have been pools created by damming up the hot water all along the creekside.

The pools closer to the cliffside runoff are EXTREMELY HOT – to the point where the water is unbearable. Keep venturing downstream until you find a pool that’s a suitable temperature for you.

Access depends on the water levels of the creek – during spring (snowmelt season) the cool water sometimes washes the pools away. During times of low water levels, the pools fill up quickly with scalding hot water. Be careful!

Bonneville Hot Springs

The Wooden Pool house (With Tub)

Up on top of the cliff, there is a wooden structure with a cast iron tub inside.

Someone manufactured this hut as a private way to soak, and funneled the water in via a PVC pipe to fill up the tub.

The wooden pool house is a fragile structure, so please use it with care! Make sure to brush up on our guide to hot springs etiquette to best care for these unique spots!

Since there is also one tub, remember that others may want to use it. If it’s busy, be mindful of your time.

Camping at Bonneville Campground

The campground is generally full during summer weekends (as expected), but it’s fairly easy to snag a spot mid-week during camping season.

You can reserve a spot at Bonneville Campground online here. There is drinking water via a hand pump on site. There is also garbage service, but it’s best practice to pack out what you can to not overwhelm the system.

There are vaulted toilets in the area, so you don’t have to worry about doing your business in the woods. It’s always a good idea to pack extra toilet paper though – these bathrooms can sometimes be maintained infrequently.
