Hot Sulphur Springs
Hot Sulphur Springs, in Grand County, Colorado, is a hot spring half a mile out of the town of the same name, and the water on file reads 111 degrees. That is hot, above the comfortable soaking range for many people. A USGS site marks the spring. The record has no owner and no access status.
Parshall Divide Road runs within about sixty feet, so this is a drive-up spring. Elevation is high, around 7,700 feet, and the climate matches: average temperature near 39, close to eight feet of snow most years, cool short summers. Willow Creek Group, roughly ten miles away, is as close as camping gets on file.
Winter gets the nod for best months. With the snow, that means counting on a plowed road into town. The water is hot enough to scald with prolonged contact, so test before you commit. No fee is on record here. Access unrecorded. Willow Creek Group is group camping by name, so check its rules before planning on it.
