Nestled in the Sweet Valley, Roystone Hot Springs RV & Event Center is a great spot for a quick dip or a day of recreation. Splash around in the natural hot springs pool or soak in the large jetted hot tub. The hot springs water comes out of the ground at 140 degrees Fahrenheit and is cooled to 98 degrees for the pool (adjusted for each season) and 104 degrees Fahrenheit for the hot tub.
