Getting There

Note: This trail was recently closed due to avalanche damage. However, the Conundrum Trailhead is now OPEN, but the trail is still covered with significant amounts of avalanche debris. For more information, please see https://www.fs.usda.gov/recarea/whiteriver/recreation/hiking/recarea/?recid=40481&actid=82 NOTE: This hike require creek crossings, which can be dangerous after a big storm. Please exercise caution. This very LONG overnight will bag you two 14er peaks. You will gradually ascend Conundrum Creek Valley as the trees get smaller and the miles tick by. Your campsite will be around Conundrum Hot Springs where you can take a soak and relax your feet after the long approach. In the morning you will head to the opposite side of the valley and follow the track in this guide to ascend both peaks. You will climb a very steep and loose scree slope up to the ridge where you will have access to both peaks. You then will return via the same way with the option of heading back up to the springs or simply returning to the trail down the canyon to shave a mile or so off.

OConundrum Creek Trailhead: Leave Aspen on westbound Highway 82. At a roundabout, take Maroon Lake Road west a very short distance then turn south on Castle Creek Road. Follow this road about 5 miles until you come to Conundrum Creek Road. Take a right onto this crossing Castle Creek over a bridge and continue to the trailhead.

We are new to 14 er's and had hoped the west ascent to Castle would pay off. WRONG!! If you are not very very experienced i would not advise. Otherwise the beauty of the trail was amazing. The hot springs were not our trophy but the journey was worth it.

Great hike through the valley! The first 9ish miles are pretty mellow with a large chunk of the elevation gain at the end. We camped at campsite #4. It is a nice spot off the trail that is close enough to the springs without being too close. Very minimal smoke if any at all.

Nature tripsBugsGreat!

It wasn’t easy but it was definitely worth it! We camped out right about 6 miles in (before the sign that says that you need a permit to camp beyond that point) all summer was booked when we looked. The last 2 miles were a B!*$@ but a wonderful reward to soak in the springs and for your muscles to relax... Will be doing this one again next year... unbelievable and breathtaking scenery/views, an unforgettable experience for sure! The river parts were not high like the other reviews said. We went on 8/1/20, water shoes were great to have specially on the muddy spots by the springs. Bug spray is a must. Enjoy!!

Notice that theres no trail marked from hot springs to the peaks. You need a gps and just walk straight to the summit through rocks. We didnt do the summit but enjoyed 18 miles of hiking and hot springs. One of our favorite hikes. Other things to notice is no camping anywhere near trailhead, parking lot is small and gets full quickly. Rangers come to check the trailhead parking. The river cross was fine with kayak shoes.

Took us 6 hours there and 4 back. Rocky parts but not too bad. Better during the week when the parking lot isn’t bad. You have to have a permit to camp at the springs I would recommend 1-8 to be closer. It’s hard due to carrying your heavy backpack for 20 miles round trip. The hot springs were amazing at the top though and worth it. Lots of mosquitoes don’t forget your spray. Lots of running water to refill water bottles.

I was worried about fording the river after reading the reviews and it was definitely a bit dangerous. My husband had to help me across. I also recommend a good pair of closed toed water shoes. We wore ours for the last two miles after the river crossing because of all the creek crossings.

The views are amazing. The hot springs is warm but not hot. The river crossing was very dangerous right after a big storm. We had a hard time crossing and saw some people get in really big trouble. Do you research on how to safely cross a river with a big backpack before attempting this trip right now. Also aim for an early morning crossing if possible, when the water is lower. We had no issues with snow. You do not need spikes or snow shoes at all right now.

My son and I hiked in for an overnight stay on June 3rd for my birthday . The snow was toward the end and very manageable. There are a lot of areas with avalanche debris . The big water crossing appx 3 miles from Conundrum Hot Springs is insane ! We needed poles and I needed an outstretched hand from my grown son .. other than that , it was hard , it was amazing and I can’t wait to repeat !

Unfortunately only made it to silver dollar pond where I set up camp for the night. By the time my boots were dry the next morning I decided to save it for another day. If you plan on going anytime in the next 2 weeks I highly recommend snowshoes (which I didn’t have) about 5 miles in from the trailhead it was mostly snow. Can’t wait to come back and give it another try soon.

Absolutely beautiful. Some snow made trail finding a little tricky. Four and a half hours to the hots springs. A little less that four hours back to the car.

So after parking out on Castle Creek road and walking in from there to the trail head this morning, I was unhappy to see that I could have driven. Yes, the road is now open again, and the trail head parking area has been uncovered and functioning. We were there like a week or so ago and the road was still roped off. Oh well, 1 mile in and back. I only went in here to see the massive avalanche that had taken out what they think is in the neighborhood of thousands of trees. After walking over the debris fields, that’s probably pretty accurate. Just insane. I can’t imagine the snow piles that are under the trees and pine duff will even melt this summer. They literally provide a blanket protecting the snow from the sun. We’ve seen lots of these debris fields this summer and they are just mind boggling to stand next to. This one is huge to say the least. People are trekking up the canyon though, as the trail just goes right over the top of the snow fields. And when it finally does melt down, the amount of trees within the snow that you can’t see right now, will be equally mind boggling. Only 3 stars as this wasn't really an all out hike for me. Some day

From forest service: “The trail remains open; however, the majority of the trail is snow-covered, and many sections are buried under large amounts of avalanche debris. Route-finding is expected to be difficult. Many avalanche and debris hazards exist beyond the trailhead.” Also currently no parking in the vicinity; hikers must be dropped off. Repair work on parking lot to begin June 17.

Absolutely loved this hike. Beautiful views the whole way. Went in fall and the aspens were gorgeous beyond words! The hike itself isn’t super difficult but it is long and I recommend camping since it is about 8 miles in and 8 miles back. The hot springs at the end are one of the prettiest places I’ve ever been to, very serene and also super clean. We ended up hanging out there for over 4 hours because the water felt so nice and we also met some other cool people who had just done the hike. I will highly recommend this trail to anyone who is up for some camping!

Be ready. Prepare. Physically and upstairs. And it will be one of the most memorable camping experiences. Period.

I am looking for someone who has actually hiked both the hot springs and conundrum/castle peaks. Looking to do this hike this weekend and would like information on trail conditions, snow on trail, recent weather, any tips, trail finding difficulty, etc. If anyone could comment back on here, I'd be super grateful! Can't find much information online.

Great trail, nice hike and overnight stay. Not as dirty as everyone says. however the summit trail is long gone on this side of castle and conundrum peak. Unless you want to ascend a scree slide at a 60 degree angle for 3k+ vertical feet.

Dogs are prohibited here. it's in the Snowmass wilderness. This is protected wilderness. you may get a huge fine. Better do your research.
