I hit up hot springs all around the Northwest during my Summer off time but good old Green Canyon is just thirty miles from my front door. No camping out, I shower when I get home, and sometimes I just rip my wet shorts off when I get back in the truck and drive home naked.
The hot pool area is separate from the swim area so it’s usually pretty quiet on weekdays. They keep it hot (108°) and it’s only $5.50 for old guys like me. Thumbs up!
