About these waters

Also known as Cougar Hot Springs, this is a set of cascading rock pools in the Willamette National Forest where hot water tumbles from an upper grotto down through progressively cooler basins beside a cold creek. Reached by an easy quarter-mile trail off Aufderheide Drive, it runs dawn to dusk with a small per-person fee and a two-hour visit limit. Clothing is optional and the top pool closes Thursday mornings for cleaning.

Good to know

  • Listing researched October 2026 — prices and hours change, always confirm with the spring before visiting.
  • Hydrate between soaks and limit hot soaks to 15–20 minutes — mineral water dehydrates fast.
  • Wild springs run on the honor system: pack out everything, leave the pool cleaner than you found it.

Terwilliger Hot Springs: FAQs

Do I need to book Terwilliger Hot Springs in advance?

For day-use admission, popular resorts sell out on weekends — if the official site offers reservations, book ahead. Weekday visits are usually easier as walk-ins.

Are kids welcome at Terwilliger Hot Springs?

Many developed springs welcome families, but age rules, family hours, and adults-only pools vary by property. Check the official site for the current policy before visiting with children.

How long should I soak at Terwilliger Hot Springs?

Start with 15–20 minutes, then cool off and hydrate before going back in. Hot mineral water dehydrates you faster than you expect — drink water between soaks and don't push through dizziness.
