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.



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.
