There are naturally occurring mineral hot springs located in Colorado. Pagosa Springs is a primary location. The springs are diverted into different pools and temperatures controlled by adding cold water. The starting temperature of the water is 145°F and is cooled down to between 98°F and 110°F. You can then choose in which temperature you would like to enjoy and relax.
The drawback to the springs is the strong smell of sulfur. If you can ignore the smell then the springs are quite refreshing and soothing to a tired aching body. Through the years these springs have been considered a medical healing treatment for the body.
After your visit, it is essential to shower with soap in the available areas to remove not necessarily the minerals but the smell of the sulfur. If not, it will stay with you till you do.
After the walking tours I took, it worked wonders in relieving the muscle aches and pains in my body. With a discount ticket I obtained for $13 for a day pass, I was able to stay as long as I wanted. At the spa, they offer towel rentals and locker rentals if you need them. You can bring in food and drink in unbreakable containers.
