A timeless ritual, made social
We’ve built The Springs around community and gathering, nestled between the mountains of Leavenworth – and soon, as an oasis to the streets of Seattle.
Hot pools among flowers. A wood-fired sauna named Darla. A cold plunge that leaves you breathless and fire pits that run past sunset.
Feel the contrast work on your body. Then do it again – with a new view, or someone new. Our space is designed for hydrotherapy the way it was meant to be: unhurried, communal, and with a mountain view that makes you forget what day it is.
How to spend your day with us
The Springs doesn't ask you to use it in any particular way. Just show up, settle in, and let your day figure itself out.
In the soaking pools
Waist-deep among wildflowers, an hour into a conversation you didn't plan to have…
…overlooking these mountains
On the chaise (or hammock)
Book face-down. Mountain view. The kind of quiet that actually works.

At the bucket
Someone is always daring someone else to pull the chain. It's always worth it.
On the grass
Book club. Live music. Enchantments hikers lying horizontal. All valid.
By the fire
The fire pit is where the evening starts, every time.
With ‘Darla’
Our retro wood-fired sauna trailer. People come just for her.
❋
Recovery and relaxation doesn't have to be quiet! The Springs gives you the space to open up – where conversations start, friendships form, and the week finally lets go.
Come solo. Bring your crew. Either way, you won't leave the same way you arrived.
We don't ask you to be silent. We ask you to be human.

Not at all. There's no set circuit and no pace to match. Our team will point you in the right direction, and your body will figure out the rest. Most first-timers are surprised how quickly it clicks.
-
Contrast therapy, sometimes called thermal contrast therapy or hot-cold therapy, is the practice of alternating between heat (sauna, hot soak) and cold (plunge) to relax muscles, sharpen the mind, and leave you feeling reset. At The Springs, you move through it outdoors, at your own pace.
-
A swimsuit and a water bottle. Towels are provided, the showers are stocked, and our bathrooms get compliments daily. Bring a book if you're a chaise person.

Both, honestly. Some guests never leave the hot pool conversation. Others read in a hammock for three hours. The site is big enough that you'll find your corner.
-
Minutes from downtown Leavenworth, walking distance from the Willkommen park & ride, and right next to the Leavenworth KOA. Our second location opens in Seattle's Fremont neighborhood in summer 2026.
