Really liked this hike. Just the right amount of challenge. Could definitely backpack in and camp at one of the primitive campsites. Loved all the creek crossings and beautiful aspens! This trail was a little more shaded than I had planned for so I was a bit chilly until I got moving. Will be back!

It was snowing heavily up this trail. We had a Rubicon JK. Road had probably 6 inches of snow and it’s a rough ride. Likes of rocks etc. The snow probably created the additional difficulty, but we used our lockers quite a bit and were in 4 wheel low most of the day. Coolest lake I’ve ever seen 1/2 mile hike off the trail. Best view I’ve seen my entire life. Great trip, but tough!

got a late start so we made it half way up but we will return again to finish! beautiful trail

parked at upper lot. have a Toyota highlander (lower clearance) and had a few sketchy spots driving. georgous views on the ridge around 13,000. last 1,000+ was steep, but so worth it. Beautiful, beautiful 360 views at the top. lots of boulders and rocks, steep in places. took me just under 3 hrs to the top. the soak in mt. Princeton hot springs after helped soothe the bones!

Did this hike by accident and WOW im glad i did! Moderate for a coloridian, difficult for a midwesterner like me. Absolutely stunning the way up, both the path and the view of the collegiate mountains. When you reach the top, theres a wooden pole and small plastic box to write your name in. Just a treasure of a trail.

totally enjoyed it! the aspen leaves were gorgeous!

The view at the end is worth the hike up!!! Get up on top of the big rocks for the best view!

Great day. Almost no other people. Did 5.3 mile up and back.

We started around 10 am today and it was perfect. The tree colors were amazing and the waterfall was incredible.

Amazing views! Moderate is a great description of this hike. First mile or so is the hardest, then it gets better. Coming down is breathtaking from the fall colors and views. Not a lot of traffic early morning. We started seeing more people around 10-12.

This is a beautiful trail. The trees are starting to change, which gives it an enchanting feel. My 15 year old and 8 year old loved it. We did not make it to the mine, so maybe next time.

Did this trail on 9/22/2018 with my wife and daughter and it the aspens were spectacular! I would call it moderate in some spots only because of the rocks on the trail. We took the St. Charles trail for about a half-mile but it got too steep.

Pretty views but this trail is trashed there is camping sites along the trail and I saw beer cans, food wrappers, even a tampon! I wish people would respect our Colorado wilderness! Fun little hike not much shade very hot even in late September.

Road was very rough. Views are beautiful but really need ATV type vehicle to enjoy it. I would not recommend it without off road vehicle.

Great trail a little steep at first but well worth it in the end. Spectacular views and a beautiful creek.

We enjoyed the hike very much. Beautiful scenery and spectacular falls.

Really cool hike. Great views. Easy. Interesting ruins of Douglas City and the old train tracks.

My husband and children, 21 & 19 and I hiked this last month with our 11 year old Cairn terrier. The initial ascent was hot on the exposed trail but the waterfall was worth any effort.
Yes, there is horse poop but we didn't care... we have and love horses.
I would definitely hike this again.

Great hike, easy to follow trail with lots of beautiful scenery. The waterfall is amazing and a nice place to cool off before heading back down. I started at 8 a.m. and saw almost no one, but lots of groups going up on my way down. There is some horse poop along trail, but wasn't too bad in my opinion. I went on 9/12 and leaves are starting to turn for fall.

I love the shady hike to the mill, after the mill it gets pretty steep. Overall a great hike close to home. Views from the summit are beautiful.

Hiked from the bottom lot, roughly 5200' vertical & 14 miles RT. I agree w/ Kurt below, the road isn't that bad, definitely doable in 4WD higher clearance. The last two miles of the hike are intense - around 2250' vertical.. of boulders & scree. The trail is well marked despite some of the negative comments below.. and certainly not dreadful. I second what Annie M says below.

Great easy hike. Finished 3 hours. Beautiful waterfall

Beautiful waterfall. Easy hike. Not many great views on the actual hike.

Did this yesterday from the paved road at the bottom, 5200' vertical. Didn't drive the road because of the scary descriptions, but the road is not bad. AWD (subaru) would be fine. Don't need a jeep. There is just one spot at 10,500 that won't allow a 2WD to make it to the parking at 10800. A gorgeous day with lots of hikers. Hope you like lots of bouldering! More of that here than any other 14er I have done so far. What a workout!

Beautiful fall hike. In my top 10 - views, waterfall, awesome.

Hiked August 24. Dog loved all the streams to get drinks. Easy to follow to the sawmill. After the sawmill, we had trouble telling if we were on the trail due to scattered cairns and trail tape. Did get to the top somewhere along the way-and back down-without getting lost. Nice views from the top. Recommend 4wd to get all the way to the trailhead. Our Subaru crosstrek got there without too much trouble.
