Conundrum Hot Springs - 17.0 Miles Round-Trip

The Conundrum Hot Springs are located 8.5 miles from Conundrum Creek Trailhead off Castle Creek Road in the Maroon Bells-Snowmass Wilderness. The hot spring complex contains two main pools and four smaller springs with a combined approximate discharge of 130 GPM, and max avg. temperature of ~100 degrees F (each pool varies).

The 8.5 mile distance would usually command a 'difficult' rating, however most consider the trail quite moderate. Strong hikers can easily achieve the roundtrip in a day with an early start.

While the springs are the main attraction, the hike in is equally compelling. The Conundrum Creek Trail runs through long stretches of level meadows, aspen forests and wide valley openings to the springs. 

Conundrum draws thousands each summer, most who camp in the immediate vicinity. Expect crowds and minimal privacy during peak months, especially weekends and holidays. The springs also serve as a first stop on longer routes to Crested Butte, Copper Basin and East Maroon Pass.

Important Camping Update: Conundrum Hot Springs will be transitioning to a permit-only system in 2018. All overnight users will be required to purchase and carry a permit when camping between Silver Dollar Pond and Triangle Pass.

Permits are available at

See Camping, Rules & Regs and Worth Noting below for additional information on designated sites, bear canisters, fire restrictions, dog restrictions and travel tips:

The trail dips and rises across a broad meadow that funnels into conifer and aspen along the creek (1.0 miles : 8,970'). It emerges in a small meadow at 1.75 miles, then the first of several major meadows at 1.85 miles (9,240').

Travel is quick to a bridge leading to the west side of the creek (2.75 miles : 9,390'). The bridge is elevated and narrow - consider crossing in the water if slick or carrying a heavy pack. Mild grades continue across a second large meadow at 3.85 miles (9,550'), past which it steepens on rugged terrain above a deep gorge in the valley (4.5 miles).

Note young aspen and fireweed on these steeper slopes, which indicate a recent disturbance that renewed the natural forest cycle.

The trail enters a third major meadow at 4.8 miles that stretches (with brief interruption) to a bridge leading east to the Silver Ponds (6.0 miles : 10,240'). Dogs are not permitted beyond this point.

The trail skirts marshy ponds to a marked creek ford back to the west side (6.55 miles : 10,320'). The ford can be voluminous at peak runoff, but is generally safe and easy. The trail opens across a talus field with your first clear view of the upper valley (7.2 miles : 10,455').

It steepens away in a cluttered forest to a sign on the hot springs perimeter (8.15 miles : 10,965').

Camping is only permitted in designated sites beyond this point, and fires are not permitted. There are several campsites just before this sign along the creek where fires are still permitted.

The trail hops a creek braid and opens past spurs for designated sites to the split for Triangle Pass. The Conundrum Hot Springs are located across the creek about 100 yards away (8.5 miles : 11,222'). There's one large pool and one small pool in the main area where most people congregate. Clothing is optional, and expect a lively crowd.

The springs are at treeline in a valley topped by Cathedral Peak (13,943'), Conundrum Peak (14,022') and Castle Peak (14,265'), which share a similar geologic make-up and appearance to Maroon Bells. The Conundrum Creek Trail continues 2 miles and 1700' up to Triangle Pass.

Worth Noting

  • The Conundrum Creek Trail sees heavy traffic throughout the summer, especially on weekends. Backpackers at the springs will experience little privacy, if any. Consider camping down-valley, where sites have more space between them. Campfires are permitted in sites outside of the designated camping area at the springs.
  • Trailhead parking is very limited and often full. Arrive early to secure a space. Overflow parking is available on Castle Creek Road, a little over one mile away. Be mindful of private property on the trailhead access road - cars will be ticketed and/or towed.
  • There are several creek crossings on this trail - expect to get wet.
  • Consider post-Labor Travel for lighter crowds. Aspen and willow produce brilliant autumn colors, and thimbleberries and raspberries are particularly abundant along the first three miles.
  • Help keep the Conundrum Hot Springs area clean by packing out all that you take in, and picking up trash along the way.

Trip Reports

"Conundrum Hot Springs is relatively moderate for hikes in the Aspen area, but fairly long - especially with snow cover and carrying an overnight pack. Still, if willing, it's certainly achievable. Just allow plenty of time to reach your campsite. If you have more than one night, it might be best to camp a few miles before the springs and day hike to them and back to your site. (You also may enjoy the privacy and quiet of campsites away from the springs - they can get quite 'lively'!) "

"Can teens and a 9 year old make this hike?"

"The trail is definitely not 8.5 miles one way. Be prepared for much more. Also watch where you step by the campsites, human land mines are everywhere. "

"Deepti - you'll definitely want sturdy shoes for this hike. Though you can enjoy the springs area with sandals, the 8.5 mile hike to them is rugged (lots of rocks, roots and several stream crossings)."

"Hi, We are planning to do conundrum hot spring hike as a day hike. Was wondering about the terrain, should I carry hiking boots or good hiking sandals will do ? Appreciate any suggestions. Thanks"
Deepti  -   -  Date Posted: July 18, 2016
"So worth it. The trip was beyond amazing and beautiful. The hike up there was moderate, to difficult in the fact that you are carrying weight, you have to cross the river a couple of times and maneuver a boulder field. If you are not in decent shape or haven't had experience carrying weight the trip might be very long and tiring, but regardless it will be WORTH it. Upon reaching the top there are 16 different camp sights to choose from, half are below the sprigs, and the other half above. When you do make it to the top I highly suggest you immediately drop your pack and run to the springs, and I promise your efforts will be rewarded and your body will thank you! Also I would suggest bringing some sort of water shoes for the hike/the springs! Enjoy! "

"It was gorgeous!!! I can't wait to go back up and get in the water with such amazing views. It lookes like we were in Hobbit land. Plush and green untainted nature (by humans). Definitely stay 1 nighy at the LEAST. I would recommend 2 nights to get even more fun out of the hike as it is lengthy. It was a full moon taboot so there were some drunk folks talking about lady gaga but I still loved every moment of it even if I wish they would've been more quiet and lesa drunk. Also, one IMPORTANT TIP: Do not wet your hair because if it gets to sunset w/o your hair drying, you will freeeeeze! I thought I was going to freeze to death but survived. Had I not wet my hair, the night temperatures wouldn't have been as bad. Especially with no campfire. "
