  1. Probably not due to having to hike a trail to reach the pools.

  2. Cougar is always busy. Go early on weekdays for your best bet.

  3. Always crowded… go early on weekdays if possible.

  4. Anyone spending their weekend there? Any current info would be helpful.

  5. Has anyone been in the past few weeks?

  6. If roads are closed due to snow is it still accessible via a hike?

  7. I will be in Oregon in March and I want to know if there are any changes, new rules, or new fees I should be aware of. Thank you so much.

  8. I went here on a Saturday in mid-march and it was fairly crowded. About half nude and half clothed. The water wasn’t as warm as I expected and the bottom pool was completely cold. Decent drive in though the roads are narrow on a semi windy road. Beware of deep potholes right past the “Loose Gravel” sign. Nearly took off our front bumper. Beautiful scenery and great experience though.

  9. went today around 3pm-5pm. It was fairly crowded, the trail was somewhat muddy. With a small group of friends it was fun, however, the largest and warmest pool was overcrowded with nude people, which was fine, but not our style. The water was kind of gross but could have been worse.
    Overall enjoyable experience, would have been more fun without the nude crowd, but we knew what we were getting into.

  10. Not really into being totally naked around strangers but met some nice girls , who were, and had a good time talking to them and visiting with the crowds that started filtering in. The water was a little cooler than say Bagby but it was good clean fun, no drugs or effing on site which was nice. Very ideal picturesque nature area, sad that there are so many dams out there, but its not as overran as Mt Hood National forest tends to be and there are some good fishing runs down there.
