Hiking Instructions: From the parking lot, backtrack on foot to the Terwilliger Hot Springs Trailhead sign on the other side of the road. Take the path along the outside of the railing, less than 0.1 miles along the way to the springs, a spur trail goes to the left down to a swimming area.

Comments: Probably the most popular "free" hot spring spot for Eugene residents, it inherits much of that city's culture and is often a stop of the Rainbows (Not the football team from the University of Hawaii). Nudity can be expected at both the springs and the swimming hole. The hot springs are constructed, but very rustic, pools set into the hillside. The source and top pool is the hottest, with the temperature cooling as it travels from pool to pool down the hill. There are eight pools ranging from 3-12 feet across and about 2-3 feet deep. The source is 112 degrees F and cools accordingly. Mostly on bedrock, the floor does have some gravel, sand and debris at the bottom. The area is day-use only and sees an abundance of use. Please do your part to keep the site pristine.
