Nearby hikes on All Trails. Be sure to bring plenty of water, sunscreen, and snacks! I recommend Easy to Moderate hikes for non-Coloradoans due to the potential for altitude sickness.
This is a free hot spring next to the river in Carbondale. Bring your own towel and sandals. Flashlight needed if going at night.
Another free hot spring. Deeper than Penny Hot Springs. Bring your own towel and sandals.
