Pine Flat Hot Springs
Eighteen miles or thereabouts from Idaho City, in Boise County, Pine Flat Hot Springs sits on Boise National Forest ground that anyone can use.

Climate figures show more than ten feet of snow a year and close to three feet of total precipitation, so the state of the road matters as much as the spring does.
