Cougar Hot Springs in Oregon

One of the highlights of our Oregon trip was always destined to be Cougar Hot Springs, otherwise known as Terwilliger Hot Springs. Nestled away in a remote part of Oregon (1 hour from Eugene), Cougar Hot Springs comprises of multiple cascading hot pools surrounded by towering trees and nothing but miles and miles of wilderness.

Getting to Cougar Hot Springs and Opening Times

Cougar hot springs are officially closed from sunrise to sunset (and Thursdays 8am-12pm for cleaning), so in an effort to avoid the crowds, we aimed to arrive just as the sun rose at 7am. That meant setting off a little after 5.30am from Eugene (a 1hr 10 minute drive), factoring in the short walk from the trailhead.

We’d heard that Cougar hot Springs tended to be quite crowded, so our early start was an effort to beat the rush. Even when we arrived though, there were already half a dozen cars parked in the lot. Not a great sign, but you can’t always have hot springs to yourself!

Make sure you poke your head over the edge of the car park and check out the incredible reservoir below!

A Short Walk From The Parking Lot

From the carpark, the hot springs are a short 5-10 minute walk through the forest (1/4 mile), depending on your pace. The trail winds gradually uphill, but it’s not particularly strenuous. This seems like a fairly easy place for thieves to break in, so make sure you don’t leave anything valuable in your vehicle.

Once we arrived at the hot springs, we were disappointed but not surprised to see about 7 or 8 people already bathing in the top pool. For obvious reasons, the top pools is always the most popular as it’s the warmest and in this case, also the biggest. According to the Forest service website, temperatures range from 112F in the top pool to 85F in the lower pool.

Past the top pool, the 5 other pools were actually completely empty, and more importantly, hot. We decided to skip the busy pool and dive (metaphorically) into the lower pools. The water was the perfect temperature, so it was here that we decided to settle in. After such an early start, the warm water and dim light was the perfect place to relax, and as more and more people started to trickle in we were glad of our decision to set off early.

Other Important Info (Toilets, Price etc)

Terwilliger (or Cougar) is another clothing optional hot spring, so of course many of the bathers were nude. Bear this in mind if you have a fragile disposition! According to the forestry website, nudity is permitted as long as there’s no visible nudity from the road….so I guess don’t walk the quarter mile from your car in your birthday suit!

There are no changing rooms at Cougar, so there’s nowhere to hide as you change, but there is a covered shelter at the springs to leave your belongings in.

Technically Cougar is also not a free hot springs, and it costs $7 per person or $66 for an annual pass.

Use the Toilets in the Carpark

The car park has some pit toilets that were actually in fantastic condition. These are the only toilets you’ll find in the area, so don’t wait until you reach the hot springs. It’s clear that some people don’t realise this before they get there because I almost stepped in some human poop by the lowest spring. Be careful where you walk!


Overall, Cougar Hot Springs are absolutely beautiful, and getting there earlier or later in the day would be our recommendation. If you’re making a day of it, it would also make sense to stop in at Bigelow Hot Springs around 32 minutes away.
