Terwilliger Hot Springs (aka Cougar Hot Springs) is one of the most beautiful natural hot springs in Oregon — and one of our personal favorites. In this guide, we’re sharing everything you need to know before you visit, including updated fees, rules, and tips.
Terwilliger Hot Springs (more commonly known as “Cougar Hot Springs”) is one of our favorites in the entire state of Oregon.
We have personally been to Cougar Hot Springs several times, and a lot has changed over the years. There is now a time limit for how long you can soak, and the price per person has increased from years past.
But one thing that hasn’t changed is the magical forest setting and the warm, healing waters that are well worth the drive (& the increased price, in my opinion).
In this guide, we’re sharing all the things you need to know before you visit this iconic Oregon hot spring!
We’ve also done our best to keep this information up to date (there’s a lot of outdated info out there!).

Our personal experience at Cougar Hot Springs
We have been to this hot spring several times, in different seasons. We’ve visited during the summer, the winter, and the spring.
And on top of that, we’ve also been here at different times of our life:
- without children
- with one baby
- and with 2 little kids
This means we have a pretty unique perspective on what you need to know before you visit. Check out our short video below to see our most recent experience!
Terwilliger (Cougar) Hot Springs Overview
Nestled in a lush canyon in Oregon’s Willamette National Forest, Terwilliger Hot Springs is a PNW treasure. Also known as Cougar Hot Springs, this magical spot features four cascading pools set in an idyllic, woodsy setting — a true hot spring lover’s paradise.
Cougar has some of the clearest water of any natural hot spring we’ve been to in Oregon because it is cleaned on a weekly basis. The water is virtually odorless, which is a welcome change from some of the sulfur-heavy springs you’ll find elsewhere in the state.

Paying the entry fee
Before hiking in, you’ll stop at a small booth to pay the $12 per person entry fee (children under 12 are free). You will be given a wristband to wear during your visit. The ranger on duty keeps track of arrival times, so be aware of your 2-hour window starting when you check in.
Insider tip: Download Google Maps offline before your trip — there is no cell signal at or near the hot springs.
Tips for visiting Terwilliger (Cougar) Hot Springs
- Arrive early or visit on a weekday. Early mornings and weekdays are the quietest times. Weekends can get busy, especially in summer.
- Be ready for the 2-hour limit. You have a 2-hour window from when you check in to soak and return to your car. The ranger on duty keeps track of this, so don’t lose track of time.
- The top pool is the hottest and most popular. It’s fed directly from the natural water source. If you want more space, check out the lower pools — they’re cooler but often less crowded.
- No alcohol allowed. Glass containers are also not permitted near the pools.
- Clothing is optional. This is common at most wild hot springs in Oregon. Be respectful of others and mindful of photography.
- No cell service. Download offline maps and directions before you leave home.
- Use the toilets at the parking lot. There are no bathroom facilities near the hot springs — there are two pit toilets in the parking lot.
- Practice Leave No Trace. Pack everything out — yes, even if you see someone else’s trash! Please help keep places like this beautiful for years to come.
- Bring snacks and water. There are no services on-site. Hydration is especially important when soaking in hot water.
- Gas up beforehand. The area is remote. There is a Chevron on the McKenzie Highway near the Cougar Dam Road turnoff, but don’t count on it — start your trip with a full tank.

Best time to visit
Terwilliger Hot Springs is open year-round, and each season has its own appeal. We’ve personally visited in the spring, summer & winter and can say it was a different experience each time.
Summer: The surrounding forest is lush and beautiful, but summer is the busiest time of year. The hot water can also feel less refreshing when outside temperatures are high. If you visit in summer, go early in the morning.
Fall & Spring: Our personal favorites. The cooler air makes soaking feel incredible, the crowds thin out, and the forest scenery is stunning.
Winter: Typically the least crowded season, and the area stays relatively mild in terms of snowfall. There’s something magical about soaking in hot water when it’s cold outside!
Regardless of season, weekday mornings will always be your best bet for a quieter, more peaceful experience.
What to pack for Cougar Hot Springs
- Towel (and a dry bag to keep your gear from getting splashed)
- Drinking water — hydration is key when soaking in hot springs!
- Snacks (just make sure to pack out everything you bring in)
- Bathing suit (if that’s how you prefer to soak)
- Easy-to-remove shoes — hiking sandals like Chacos work great
- Clothes that are easy to change in and out of
- Cash or card for the entry fee
- Offline map downloaded to your phone before you leave
- Chemical-free sunscreen (for summer visits)
- A small trash bag to pack out any waste
Leave your alcohol and glass containers at home — both are not allowed at the pools.
Things to see nearby
The Willamette National Forest is packed with incredible natural attractions. If you have extra time, here are some of our top recommendations near Cougar Hot Springs:
- Sahalie and Koosah Falls: Two impressive waterfalls located close together along the McKenzie River. Easy to visit back-to-back on a 2.5-mile loop trail. We combined our most recent visit to Cougar Hot Springs with this hike and it made for a perfect day trip.
- Tamolitch Blue Pools (Blue Pool): One of the most stunning hikes in Oregon. Walk through old-growth forest to reach a shockingly blue, cold-water spring. It’s about 30–40 minutes from Cougar Hot Springs.
- Proxy Falls: One of our absolute favorite waterfalls in Oregon. Located on the Old McKenzie Highway, this stunning falls is well worth the short hike. Note: closed in wintertime.
- Belknap Hot Springs Resort: A historic lodge on the McKenzie River with a fully maintained, pool-style hot spring. A great option if you want a more developed hot spring experience.
- Cougar Reservoir: You’ll pass right by this beautiful body of water on your way to the hot springs. It’s worth pausing for photos, especially in summer.
Where to eat nearby
The area around Terwilliger Hot Springs is rural, but there are a couple of reliable options for food nearby:
- McKenzie General Store: A local favorite serving burgers, pub food, and cold drinks. They sometimes have live music and a beer garden — a fun, casual spot to grab a bite after your soak.
- Takoda’s Restaurant: American comfort food in a relaxed, no-frills setting. Their pulled pork potato nachos are excellent, and the outdoor seating is a great spot on a nice day.
Insider tip: Both spots are in the McKenzie Bridge area. We’d recommend stopping for food on your way back, as you’ll want to head straight to the springs while you still have energy (and parking)!
Where to stay nearby
There’s no camping at the hot springs themselves, but there are some great options nearby:
- Loloma Lodge: Our top recommendation for staying near Cougar Hot Springs. This stunning property sits right beside the McKenzie River and offers glamping tent pads, riverside cabins, and traditional campsites. It’s about a 12-minute drive to Cougar Reservoir from here.
- Cougar Crossing Campground: The closest campground to the hot springs. It’s open year-round, which is a big plus, though the facilities are fairly basic (just okay, honestly) — good if you want to be close!
- Slide Creek Campground: Another nearby option worth checking out.
- French Pete Campground: A scenic campground in the forest, a bit further out but a solid choice.
Pro tip: Staying nearby means you can visit the hot springs at off-peak hours — early morning or after most day visitors have left — which can make a big difference in crowds.
