Cougar Hot Springs, Blue River

#115 of 254 in Nature in Oregon
Terwilliger Hot Springs, also known as Cougar Hot Springs, are geothermal pools in the Willamette National Forest in the U.S. state of Oregon, 53mi east of Eugene. The springs drain into Rider Creek, which in turn drains into Cougar Reservoir. They are about a quarter mile from Forest Service Road 19, also known as Aufderheide Memorial Drive. The hot springs are managed by American Land & Leisure.
Visitors over the years built up four pools out of river stones. The pools' sizes range from 3to across and 2to deep. The water source is above the topmost pool where the spring flows from a rock face at approximately 112°F. The pools are on a hillside and cascade from one to the next so that each pool step lower is cooler than the one above it. The pool floors are mostly bedrock but some gravel, sand and debris remain at the bottom of the pools. The pools are closed Thursday mornings for weekly cleaning by the concessionaire.
The pools were renovated in 2009. A group of volunteers, led by a Eugene-based stonemason, removed concrete and built pools using a natural mortar. The new walls will be more stable and easier for volunteers to clean. The renovated pools, the construction of which cost an estimated $40,000, are expected to last for generations.
Access to the springs is subject to a fee. Since 2012, the rates have been $6 per person per day or $60 per person for a seasonal pass to visit. Clothing in the bathing areas is optional, and access is permitted for day use only. Pets are not allowed at the pools, but there is a designated area before the pools where pets can be tied up.

  • Please note that the site is closed on Thursday morninguntil 12pm due to maintenance. Access price $7 for the day After 1/4 mile of easy walking, we arrive at the site. Benches and tables allow you to put down your clothes and change. The site is free, some people are possibly naked .... If you have children.... The Basins have different temperatures, the hottest at the top, the least hot at the bottom. Hyper restful, absolutely to do.
