6 Free Hot Springs Colorado
1. Penny Hot Springs
Penny Hot Springs is a roadside gem located along the Crystal River near Carbondale. Unlike many other hot springs, it requires no hiking, making it one of the most accessible natural springs in Colorado. The pools are right next to the highway, yet the surrounding mountains provide a serene and peaceful soak. The water temperature can vary depending on the season, but it usually stays warm enough for a relaxing dip. Because of its easy access, it can get crowded at times, so visiting early in the morning or on weekdays may provide a more private experience.
2. Rainbow Hot Springs
Tucked away in the San Juan National Forest, Rainbow Hot Springs is a remote and scenic spot about 4.5 miles from Pagosa Springs. This location features two natural pools with adjustable temperatures, thanks to the nearby San Juan River. Visitors can rearrange the rocks along the river’s edge to control how much cool water flows in, making the pools customizable to personal comfort. While some visitors report having the place to themselves, it can also attract campers looking for a peaceful soak in the wilderness. The hike to the springs is moderate but rewarding, with beautiful views of the forest and river along the way.
3. Radium Hot Springs
Situated along the Colorado River near Kremmling, Radium Hot Springs is unique because its warm waters mix with the cold river, creating a refreshing yet soothing experience. Depending on the time of year, these springs can sometimes be submerged by the river’s high water levels, especially during early spring runoff. Visitors can either hike or raft to this spot, making it a fun and adventurous hot spring destination. The nearby cliffs are also a popular spot for those who enjoy cliff jumping, though caution is advised. While it may not be the hottest spring in Colorado, it remains a favorite due to its scenic location and accessibility.
4. Conundrum Hot Springs
As one of the highest-elevation hot springs in North America, Conundrum Hot Springs offers a truly rewarding soak after a challenging 9-mile hike through the Colorado Rockies. Sitting at 11,200 feet above sea level, this remote spring provides breathtaking views and a peaceful atmosphere that feels completely removed from civilization. Those who wish to stay overnight need a permit, as camping in the area is regulated to protect its natural beauty. Due to its remote location and the effort required to reach it, Conundrum Hot Springs tends to attract more dedicated outdoor enthusiasts rather than casual visitors, making it a perfect destination for those seeking a true backcountry experience.
5. South Canyon Hot Springs
Just outside Glenwood Springs, South Canyon Hot Springs is a hidden treasure that requires only a short hike to reach. These undeveloped pools offer warm, mineral-rich waters surrounded by nature, making them a great spot for relaxation. However, one of the pools can sometimes get murky, and visitors have occasionally reported uncomfortable encounters with strangers, so it’s best to visit with a friend or during daylight hours. Since it’s relatively close to town, it provides a great balance between accessibility and wilderness. On clear nights, it’s a fantastic spot for stargazing while soaking in the naturally heated waters.
6. Piedra Hot Springs
Located deep in the San Juan National Forest, Piedra Hot Springs is a peaceful spot accessible via a moderate 1.5-mile hike. The pools are naturally fed by underground geothermal activity, but rock walls have been built to help retain the warm water. Because of its remote location, it offers a quiet and tranquil escape, perfect for those looking to unwind in nature. The area is also a popular camping and fishing destination, and outside of hunting season, it’s common to see wildlife while enjoying a soak. Surrounded by lush forests and rugged terrain, Piedra Hot Springs provides a truly immersive outdoor experience for those willing to make the trek.
Tips for Visiting Colorado Hot Springs
1. Check Accessibility and Conditions
Before heading out, research whether the hot springs are accessible. Some require long hikes, permits, or are seasonal due to high river levels. Checking weather conditions and road closures can save you from disappointment.

Bring water, snacks, towels, and a change of clothes, especially for remote springs with no nearby facilities. If hiking is involved, wear proper footwear and carry extra layers to stay warm.
3. Follow Leave No Trace Principles
Respect nature by packing out all trash, avoiding the use of soaps in the water, and staying on designated trails. Keeping the springs clean ensures they remain enjoyable for everyone.
4. Be Mindful of Temperature and Safety
Hot spring temperatures vary, and some can be too hot for prolonged soaking. Test the water before entering and be cautious, especially with children. Also, be aware of wildlife and changing river levels.
5. Visit During Off-Peak Hours
To avoid crowds, visit early in the morning or on weekdays. Popular springs can get busy, so going during quieter times offers a more peaceful and relaxing experience.
