"A free, 20 minute soak in natural hot spring mineral water with an indoor and outdoor pool and clean shower and locker rooms. We weren't clear if over 20 minutes cost money or if 20 minutes was the maximum, but also they weren't constantly checking up. Also, don't miss the great boardwalk across the hot spring terraces, right behind the bathhouse. Gorgeous formations, and the boardwalk leads to an impressive rope bridge for views from the outcroppings across the river."

"5/23/2025-Soothe for 20 minutes for free in either indoor or outdoor pools. RV entrance is NOT to drive under low bridge, white signs posted have you drive couple blocks to the right of the main entrance. Plenty of R.V. parking in the park across the street with nice picnic tables and room to run the your dog. Clean showers, restrooms and pool area. The staff is friendly and informative. Pools temperatures are around 104 (hot tub warm). The Teepee room next door you can soak longer for a fee in numerous indoor/outdoor pools and they have water slides. The park next door we cooked dinner and enjoyed the picnic tables and cool breeze. This area is well worth your time."
