At 11,200 feet (3,414 m), it’s among the highest hot springs in North America. Getting there requires an 8.5-mile hike one way, but the reward is soaking in 100 °F (38 °C) waters with stunning alpine views.

What Should You Know Before Going to Conundrum Hot Springs
Conundrum Hot Springs is a primitive wilderness site with no restrooms, trash bins, or services. There is the main pool and a few smaller pools sit nearby. The springs are clothing-optional and tend to have a relaxed, social vibe.
If you plan to camp overnight, you must have a backcountry permit reserved in advance through the U.S. Forest Service. Camping is only allowed in designated zones, and permits often sell out quickly, especially on weekends.
Day-use visitors don’t need a permit or reservation, but they must hike in and out the same day. In both cases, follow Leave No Trace principles: pack out all trash, avoid disturbing wildlife, and respect other visitors.
Bring enough food, water, and warm layers, and be prepared for a strenuous hike at high altitude. Snow may linger on the trail until early summer.
How to Get to Conundrum Hot Springs
The trailhead for Conundrum Hot Springs is located about 6,8 miles from Aspen, at the end of Conundrum Creek Road. From there, it’s an 8.5-mile hike one way with around 2,400 feet (730 m) of elevation gain. Most hikers take 5–6 hours to reach the springs.
The trail follows Conundrum Creek through forests, meadows, and several stream crossings before reaching the hot springs. Snow often lingers on the trail until early summer, so conditions can vary greatly depending on the season.
Parking is limited at the trailhead, and it fills up quickly on weekends. Arriving early is strongly recommended.

Best Time to Visit Conundrum Hot Springs
The best season to visit Conundrum Hot Springs is July through September, when the trail is generally snow-free and stream crossings are safer. In spring and early summer, melting snow can make the path dangerous, with high water levels at creek crossings and snow covering upper sections of the trail.
Autumn offers brilliant foliage and fewer crowds, while winter is only suitable for experienced backcountry travelers with skis or snowshoes. Soaking in the hot springs surrounded by snow is unforgettable, but conditions are harsh and require serious preparation.
Opening Hours and Entry Costs in Conundrum Hot Springs
Conundrum Hot Springs are open year-round and free of charge. There are no entry fees for visiting or soaking in the springs.
However, if you plan to camp overnight, you must purchase a backcountry permit from the U.S. Forest Service. These permits are limited and must be reserved in advance through the online system. Day-use visitors do not need permits but must be prepared for the long hike in and out on the same day.
Because the springs are undeveloped, it’s important to follow Leave No Trace principles: pack out all trash, avoid bringing glass containers, and keep noise levels down to preserve the wilderness experience for everyone.
