Terwilliger Hot Springs


As you walk the 1/4 mile trail to the hot springs, you are enveloped in the dark hues of primeval woodland, touched by mottled light filtering down from treetops high above and the invigorating scene of the lagoon with the gorgeous Rider Creek waterfall spilling into it.

There are five soaking pools spaced apart by rock walls laid out in steps down a ravine. The pool floors are mostly bedrock but some gravel, sand and debris remain at the bottom of the pool.

Clothing is optional at the hot springs.

The .25 mile long trail to the hotsprings is composed of densely packed gravel and soil and is not maintained for wheelchair access. The trail is generally low gradient, however in a few areas there are short, steeper grades that may be difficult for people with mobility limitations. During the winter, snow and ice accumulations may make the trail particularly difficult. Narrow rock steps lead to the pools and are not wheelchair accessible and may pose a challenge for someone with mobility limitations.



From Blue River, OR, travel 4 miles east on Highway 126 to Aufderheide Drive (Forest Road 19).

Continue on south Aufderheide Drive, taking a right at the Y to the top of Cougar Reservoir. Continue south on Aufderheide Drive for 5 miles to Terwilliger Hot Springs parking lot.

The parking area is approximately 300 yards away from the entry station for the hotsprings and the Rider Creek Trail #3319 continues west another 1/4 mile to Terwilliger Hot Springs.

Parking lot capacity is limited and parking with any portion of a vehicle on the paved surface of Forest Road 19 is prohibited.
