Hiked this trail on 11/10. Like the other two posts mentioned the trail is significantly covered in ice and snow with a decent amount of foot traffic. Be prepared to slide and have a few good wipeouts. The views along the trail are spectacular and I’m looking forward to going back again in the spring, summer and/or fall when the aspen leaves are changing. And yes the 30min drive on the dirt road is pretty rough, but if my Sentra can do it then all other vehicles can also.

Hiked this trail 11/10/18. The 9 mile road, like others mentioned, is pretty rough but it was well worth the hike! There’s plenty of great viewing spots on the way to the lookout station. The only thing I’d note is that it was pretty icy when I went. Many people (myself included) were sliding and took some bad falls. However, if you’re prepared for the icy conditions it’s well worth the drive for the 360 views of mountains.

Some of the best views from any trail in Colorado. Before I got to the trail head I had a bear run across Rampart Range Road in front of me, he was a light brown color. Hiked on 9 Nov 18, started about 0900, temp was 27 degrees at the trail head. Trail is almost totally covered in snow and ice, wear crampons or micro spikes so you don't fall. The stairs to the top are mostly snow/ice covered, best hang on tightly on the way up and down.

Lots of snow this morning! Make sure you are prepared if hiking in the snow. About half the trail I was second person then almost all of Flagstaff on the way back down was breaking trailhead. Snow ranged from 2-3" to about 8"-10" deep at points. Waterproof boots are a must. I did wear spikes but didn't really need them for the most part. Not a ton of views due to currently snowfall. But there were several spots where it was still very pretty despite minimal views. I would def do this trail again when it isn't snowing. Worth the hike for sure.

Awesome hike. Not overwhelming hard but tough for moderately in-shape folks. Mostly climbing steps. Gorgeous view at the top.

Trail was not super tough. I would highly recommend using spikes. I did not and was fine. Just watch where you’re stepping. Though my wife did use spikes and said she felt much more comfortable coming back down. There was an incident with a dislocated hip. Not sure if it was from a fall or whatnot, but it is better to be safe than sorry. As you get further up trail you run between dry land/rocks and icy areas. The end is def worth the hike up. Just be careful!!!

Beautiful trail. well maintained and not much traffic on the trail today because of the cold may be. But the parking lot is full as there are lot of trails starting at the same place. I have parked on a close by street. It snowed a bit while I was there and it was beautiful

My favorite trail in Boulder. I do it several times a year in all different seasons. Traction is definitely a good idea in winter. Can be crowded. It is steep. But I still love it. On clear days, one can see out the expansive eastern plains, and the city of Denver in the distance appears very small and isolated.

Its snowshoe season!

Absolutely loved this hike!

Great hike! We went last Friday and it was a beautiful day. The trail was icy and snow packed in some areas and even more so the closer we got to the lake.

Pretty awesome hike close to home.

Easy hike with incredible views. dog friendly and not busy. The 9 miles of dirt road are a little rough, but we managed in our Honda Civic.

This has quickly become one of our favorite hikes. The elevation gain is serious, but there are only a few spots that get challenging. The lake is peaceful, and we had it to ourselves today. It does get snowy and icy, so wear your spikes or bring your poles.

This was a lovely hike, quite the ass kicker at the very end. Good workout and a wonderful view at the end.

Easy, family friendly...best views I’ve seen yet!

Loved it! Soooo beautiful!! View was breathtaking!

nice

Great hike. Breathtaking views from the top. Worth the climb up to the tower at the end of the hike.

Started at trail head around 930. Was pretty packed at the arch but a great hike. Some challenging switchbacks for people like us that live at sea level. Take plenty of water!!! Gorgeous views of the flatirons and surrounding valley. The arch is absolutely stunning. Will do again when I come back to the Denver/Boulder area.

It was a gorgeous day to hike. I started early and there was no one on the trail all the way up to Diamond Lake. I did wear spikes the entire way due to ice and snow. I couldn't have hiked the last mile without them. My dog was with me and we had a blast. Yes, the road is awful to drive on but if you're a confident driver, you can make it. Please PULL OVER if someone is behind you and you're coasting down (or up) the road. It was a celebratory hike for my 61st birthday and the day couldn't have been nicer.

Went on a Saturday morning (10/20) around 9:00. Wasn't busy on the way up but packed on the way down. Challenging hike but nice views at the top and the arch is very cool.

Took the dogs and kids. Amazing drive up, beautiful views. It’s a must.

Favorite trail in Boulder!

Nice hike! Got there a little after eight and there were a few cars in the lot but I only saw three or four other people on my way up. A little icy about 3/4 of the way to the top but I did ok in just sneakers, just had to go a little slow on the way back down. Lovely views all around from the lookout. Seems like a good one to bring visitors to as it’s not too long but you get great views at the end.

The road is bumpy — you’ll definitely get jostled in a few places — but my Honda Accord made it up no problem and the beautiful drive through the forest more than made up for the bumps.
