Hiking to Conundrum Hot Springs

Hiking to Conundrum Hot Springs in Aspen, Colorado

Deep in the Elk Mountains lies a natural treasure that feels like a well-kept secret—Conundrum Hot Springs. Reaching it isn’t for the faint of heart, but for those willing to tackle the 18-mile round trip, the reward is unforgettable: soaking in steaming hot springs surrounded by jagged peaks, under a sky that feels impossibly close.

The journey begins at the Conundrum Creek Trailhead, where the trail winds through lush meadows dotted with wildflowers in summer and golden aspens in fall. Early on, the path follows the soothing sounds of Conundrum Creek, its clear waters weaving through a valley flanked by towering peaks. The gradual incline makes for a pleasant start, but don’t let its ease lull you—the challenge builds as you approach the higher elevations.

Each mile offers its own magic. Wooden footbridges lead over streams, marmots scamper across rocky outcrops, and patches of dense forest give way to sweeping vistas. About six miles in, the trail begins to climb more steeply, reminding you why reaching the springs is a badge of honor among hikers. At an elevation of 11,200 feet, the air thins, but so do the distractions of modern life. The wilderness here demands your focus, presence, and respect.

Finally, the springs come into view, their crystal-clear pools nestled in a meadow with panoramic views of the surrounding peaks. The water, naturally heated to a blissful 100–102°F, feels like an embrace after the effort of the hike. Whether you arrive in the golden light of late afternoon or under a canopy of stars, soaking in Conundrum Hot Springs is an experience that etches itself into your soul.
