Public hot spring West of Glenwood Springs

About two years ago, we tried and succeeded in finding the South Canyon Creek Road hot springs, just west of Glenwood Springs, CO. This hot spring is in on public lands and is relatively small. When we visited there were three others there (a couple and a single guy) and two of them were nude. The spring, at that time, was just big enough for two people.
Locating the spring can be a challenge. Basically, take exit 111 off Interstate 70 (South Canyon Creek Road) and head south. You will cross a bridge over the Colorado River, then the train tracks. Drive 1/2 mile and stop at the large turnout on the right (west) side of the road. There is a small trail that goes down, across a lightly wooded area, then up the hill. About 100 yards out, you will see the hot springs to your right (west).
Keep in mind that this area had a forest fire about 4 years ago, so tree shade is minimal.

This summer I plan to check out Radium Hot Springs. I have heard that this spring is clothing optional and is located near the RadiumCampground, across the street and up the trail by the telephone switcher box. About 1/4 mile on the right after you reach the River Rim Trail on the Colorado River. CLICK ON THE MAP TO ENLARGE
