Hiked to Bagby hot springs and back to the trailhead/campsite. The hot springs are really cool, and I can't imagine why it's not a standard apres-rogaine thing to do! So here's the travel ad:
The hot springs are on forest service land, and maintained by the gov't. You just pay your $5 trailhead fee to park and walk 1.5 miles to the springs along a lovely trail through old growth forest with some HUGE trees.
Eventually you come in sight of the buildings housing the tubs.
The water comes out of a spring and is captured by open wooden pipes that run the length of the bath house.
You plug your tub with a wooden plug and fill it with steaming water:
There are a bunch of different tubs, big and small, more or less private. You use a bucket to add cold water to moderate the temperature. We sat in the big tub, and here is the coolest thing: we filled the bucket with cold water and slowly lowered it into the hot tub. The cold water stayed in the bucket, and I put my blistered feet into it. So there I was with my feet in cold water, and my body in hot water, and it was all the same water - wow!
