Conundrum Hot Springs

Conundrum Hot Springs

Conundrum Hot Springs is a primitive set of hot springs, with incredible views of the surrounding wilderness. It’s isolated deep in the Colorado Rockies, only accessible by a nine mile hike up Conundrum Creek Trail. The hot springs are at treeline near Castle Peak, surrounded by the Maroon Bells.


At 11,200 feet, the Conundrum Hot Springs are among the highest hot springs in North America.There are several pools of varying size and temperature. The larger pools can host about a dozen people and are around three foot deep. The temperature averages 100° F. The small pools tend to be little cooler.

The pools were formed in existing craters or rock through years of visitation. They offer therapeutic soaking in a natural environment. Around the springs are scenic views of waterfalls, flowers, snow patches, and steep avalanche chutes. While soaking you’ll enjoy looking down into the valley, marveling at the hike you just completed.

Overnight camping can be found near the springs. The spots nearest to the hot springs prohibit campfires. Try to get there early to claim your spot, and bring a couple flash lights for navigating around. The best time to go is late spring to mid fall, once the winter snow has melted.
