The Shower Bath Hot Springs are found on the Warm Spring Creek Trail. The springs are a real gem in Salmon-Challis, as this trail is quite remote and does not see many visitors. Bring your swimming gear and enjoy a swim in the hot water after the long hike to get here. There is a campsite located just to the north offering two tent pitches.
