Free Hot Springs to Hike to in Colorado

While there are a ton of Hot Spring Resorts in Colorado, it’s nice to get off the grid and have a more isolated experience in nature. Although these hot springs are free, be sure to leave them cleaner than you found them and always remember to pick up after your visit to keep these locations beautiful for everyone to enjoy. You do have to hike to these hot springs so it’s important to take into consideration of the weather as rocks may be slippery with ice at times. Some of these hikes may be more appropriate in the summer, where as others in the winter. Overall Spring typically causes overflow due to the snow melt causing water temps to drop.

Radium Hot Spring

This may be the most popular natural hot spring considering how close it is to Denver and the length  only being 1.5 miles. It can get very busy and it is very small so I suggest going on a week day if possible. They are located on the Colorado River in Kremmling. Be aware of weather conditions when visiting because there is a rocky section that is steep in order to access the springs. Reviews state the water is typically at 80 degrees so more like a warm spring.

Conundrum Hot Spring

The most challenging hot spring to reach considering that it’s the highest hot spring in the U.S sitting at over 11,000 ft. elevation. It is a 16 mile round trip hike, there and back. However, you always have the option to camp. Permits are required for camping in the area, so check out recreation.gov to purchase. The hot spring is located near Aspen, which makes for stunning views during your hike. I’d recommend going in July or August per the reviews here.

Penny Hot Springs

This hot spring is located south of Carbondale, along the Crystal River. It is a very short hike from where you park. There are no signs for the Hot Springs, but here is a detailed website with where to park.

South Canyon Hot Springs

These hot springs are easily accessible. They are located in Glenwood Springs and a perfect alternative if you’re wanting to avoid the crowds at Glenwood Hot Springs or Iron Mountain. To find the exact location use this link here.

Piedera River Hot Springs

This hot spring is located in Pagosa Springs. It is a 3 mile hike total along Sheep Creek Trail, out and back. It’s a great alternative to the Pagosa Hot Springs with 25 pools.  There are many pools of varying depths and temperature, all of which change constantly, so hopefully you find a warm one! They are typically flooded out by Spring. While you’re there check out Chimney Rock!

Rainbow Hot Spring

These Rainbow Hot Springs will take some work to access! The hike is a total of ten miles out and back. If you go during the summer you will spot wildflowers and a waterfall on your hike. This hike is located near Pagosa Springs as well. Note: There was an avalanche in the area in 2019 that resulted in damage, but reviews state you can still access the hot springs.

Millon Dollar Highway Hot Spring

This is a hidden hot spring not typically discussed and difficult to find. It is only a 600 ft hike to the hot spring, but you are unable to see it from the Millon Dollar Highway. I’d suggest visiting in the summer. It’s close to my favorite mountain town, Telluride. Colorado’s beauty deserves to be enjoyed by everyone, but always remember to follow guidelines and clean up after yourself. If you’re wanting my saved pin of this location send me a DM on Instagram.
