Mundo Hot Springs Water & Soaking

Water comes out of the ground at roughly 160°F (71°C) and is routed to two outdoor spots. A large mineral pool, typically is kept around 102°F (39°C) and slightly cooler in summer. A smaller hot tub is hotter, around 106°F (41°C).

Fresh hot water continuously refreshes both pools, so no chemical treatment is needed. The large pool is drained and refilled weekly. Guests will notice clean, clear mineral water with a soft feel and little to no sulfur odor.

Swimwear is required, and the area has bathrooms, changing rooms, and showers.

After a soak, the on-site bistro serves simple, satisfying fare including snacks, homemade soups, sandwiches, salads, and desserts—perfect for a mellow afternoon by the pool.

Mundo Hot Springs is an excellent base for outdoor recreation. The nearby Weiser River Trail offers hiking and biking along an 84-mile rail-trail that parallels the river and farmland.

You can enjoy fishing and gentle rafting on the river. Wildlife is easy to see, including birds of prey, ducks and geese, deer, and songbirds along the riverbanks.

Day trips are also fun. You can visit Hells Canyon, the deepest river gorge in the U.S., with lookout points, jet boat rides, and challenging hiking trails.

Stay the night to stretch out your soak-and-explore time. Options include:

• Pool house and cabins: Simple, comfortable lodging steps from the water.
• RV and tent campsites: Easy road access, flat pads, and a short walk to the pools.

Reservations are recommended for weekends and holidays.
