This is a very easy trail to a major hot spring.
This is a very short trail that leads from a parking area to a viewing platform of the Big Horn Spring, which is the primary water source of Hot Springs State Park. The water flowing from here has created much of the mineral formation that is now the Rainbow Terrace. Three million gallons of water flow from this spring every day at 135-degrees Fahrenheit. The trail also passes a covered picnic area on its way to the main loop of the area, Terrace Walk. Be mindful of traffic as you cross Big Spring Road.
