The Cougar Hot Springs or the Terwilliger Hot Springs in Oregon is one of the most popular thermal springs in the region that are often flooded with people, be it the summer or the winter season. Accessible via a 0.25 miles trail, the entire route to the springs is amidst the lush green woodland where only filtered sunlight reaches the ground, creating a greenish and darkened glow on the pathway. The Rider Creek waterfall is also located higher up and the water falls down into six different soaking pools.

The trail to the springs is dense with vegetation and covered with gravel. It is not suitable for wheelchair-bounded individuals. Though the slope of the trail is mostly low, it is a bit steeper in certain places. Also, access to the pools is via narrow, rocky steps.
