Terwilliger (Cougar) Hot Springs

Enjoy the 1/4 mile hike along the Rider Creek Trail (#3319) to the clothing optional hot springs. There are four soaking pools spaced apart by rock walls laid out in steps down a ravine. Temperatures range from 85 degrees Fahrenheit in the lower pool to 112 degrees Fahrenheit in the upper pool. The pools are 3-12 feet across and an average of 2-3 feet deep. The pool floors are mostly bedrock but some gravel, sand and debris remain at the bottom of the pool.

Please preserve the experience for you and other visitors by observing the following: There is no alcohol allowed, the hot springs are for day use only and camping is restricted to developed campgrounds in the Cougar Recreation Area. 

Parking is limited at this location. Please do not double park vehicles within the parking lot or park along Forest Service Road 19; this creates hazardous conditions for other drivers and pedestrians. If you have a RV, bus, or vehicle with a trailer, please park at the pull out along the road near Forest Service Road 1985/1986 or in the Cougar Crossing Day Use Area

Current Conditions
This site was heavily impacted by the 2018 Terwilliger Fire. While hazard trees have been mitigated around the hot springs, other risks persist. When visiting, other potential hazards include: loose rocks, flooding, debris flows, and weakened trees falling.
