The answer
Cougar Hot Springs is the name people search. The Forest Service name is Terwilliger Hot Springs, Recreation.gov POI 244166. Official: https://www.recreation.gov/hiking/trailheads/244166 Six pools, water roughly 85–112°F, about a quarter-mile trail, clothing-optional, no alcohol, day use — those are the published recreation.gov facts. Access is Highway 126 through Blue River, then Aufderheide (Forest Road 19) past Cougar Reservoir; the winter road is not maintained. From Eugene this is a McKenzie corridor day trip, not a Saturday-market errand. Pass and seasonal gates change — confirm on Recreation.gov and Willamette National Forest before you drive. Housing that lives this soak is Vida, Blue River, McKenzie Bridge, and some Springfield owners who already drive 126. Downtown Eugene is the other direction. Cheyenne works the McKenzie — this is her corridor, not a spa brochure.

Recreation.gov Terwilliger Hot Springs (www.recreation.gov/hiking/trailheads/244166). Fees, gates, and clothing policy belong to the Forest Service listing — we will not freeze a dollar amount here.
What ranks on page one — and what we add
Recreation.gov, travel blogs, and AllTrails. Google wants hours, fees, clothing-optional, and the drive. The federal page is the source of truth. We cite it. The gap is which Lane County houses actually make this a regular soak versus a once-a-year tourist run.
The drive from Eugene
East on 126. Springfield, Walterville, Vida, Blue River, then the reservoir road. In summer it is a committed afternoon. In winter it can be closed or ugly. Do not treat Google’s summer ETA as a January plan. Waterfalls on the same corridor are a different URL.
Which houses sit on this life
McKenzie Bridge and Vida buyers are already on 126. Springfield east-side can make the soak without crossing all of Eugene. Cal Young and South Hills owners still go — they just do not go on a Tuesday after work. If the brief is hot-springs lifestyle, we start on the river, not a downtown loft.
What this page is not
Not a second waterfalls essay, not McKenzie fishing, not a Belknap or Breitenbush page. Terwilliger is this soak. Rules, fees, and clothing policy belong to Recreation.gov.

A real miss
They wanted weekly soaks and bought Fairmount
The house was pretty. The drive to Blue River after a full week was a fantasy. We put them in Vida with a 126 commute they already understood. The springs did not get closer. The life did.
