Free/dispersed only. The hot spring is amazing and worth going as far as you can down a very rough road. We camped right next to the warm creek, about a quarter mile before the hot spring and walked to the spring several times a day. There were days when we had the spring all to ourselves, weekends got crowded. Scenery is beautiful with the meandering warm creek and the mountains. Did we mention the roads were incredibly rough? Otherwise five stars.
