Awesome trail! Arrived at 8:30am and parking was already packed. Didn’t see many people on the trail until about almost half way there when people started to come down. Fairly easy trail until you get close to the summit, then it’s rocky, steep and definitely a workout. Views on the entire trail and they are amazing!

Nice hike that is mostly a walk in the woods until the last quarter to half mile, which is steep uphill to the summit. A beautiful trail that has a good amount of shade and also some meadows. Wildflowers are out now. We arrived at 7:30 on Saturday morning and had plenty of nearby roadside parking. It was not too crowded but definitely saw more people on our way back down.

Beautiful wildflowers the whole trail, got lots of great pictures! We made much faster time coming down since I didn’t stop every 50 feet to take pictures. Biggest surprise was the fabulous mountain vistas at almost every point along the trail. Lots of traffic, especially at the top (the last 300 feet was the hardest part of the trail with big incline and a lot more rocks, just keep climbing!), but the views were amazing and we got to watch 100s of butterflies dance, magical! Great stretches of sun and shade, perfect mix. Social distancing requests were mostly observed, many had masks.

Hiked this trail on Saturday morning. We arrived at 7:45AM and there were already a lot of cars parked along the road. To our surprise there weren't a lot of hikers on they way up. Most of the hike was pretty easy, the last stretch getting to the top was was difficult, mainly rocky and steep. Once we started making our way down, we ran into A LOT more people. I definitely recommend getting there early. Overall, great hike and views, the weather couldn't have been any better!

You’ll love this trail: It is well maintained by City of Boulder, it’s the first trail you don’t have to pay to park, it’s the right level of intensity for someone looking to increase their activity level & it has gorgeous views throughout 5/5

Nice hike for the most part. Pretty easy most of the way. 3 stars because I didnt think the top of the trail was great. Not a lot of room and trees blocking most of the view.

Trail is in great shape. No mud at all. Started around 3:30PM and there was a decent amount of folks and almost everyone was wearing masks, which was great to see. Final third mile up to the summit was a good climb. Views were spectacular the entire hike.

Hill climb w/ HJ to test the hip injection. No go! Beautiful day, though. Sunny, hot (about 90) and windy with a sky about as blue as it gets! Delightful if it weren’t for the last mile and a half of hurting!

Well-trafficked in the AM hours. Plenty of friendly people, about 1/2 wearing face masks. Wildflowers, flora, and fauna are stunning. Spotted several mule deer crossing the path close to noon. Small outlooks are gorgeous, make sure to stop & take in your surroundings! The last half mile to the peak is uphill, but manageable for all fitness levels and absolutely worth the view. There’s a peak map at the top that faces west, but it’s difficult to interpret.

Such a beautiful hike! It was way tougher than I expected, especially towards the end, but so worth it. The views are amazing and the entire trail is really lovely. It was a bit crowded for sure, and the trail is fairly narrow, so keep that in mind for social distancing purposes.

Great hike! Killer towards the turn around point / peak but definitely worth it!

It was overcast and rained a bit so looking forward to doing it again on a clear day. Great views. The sacred cliffs area is closed until August 1st due to nesting raptors. This trail is better than the pictures.

Beautiful, dry trail but heavily trafficked. We arrived at 8am and there were only about 5 cars but by the end, there were a ton of people so get there early! Easy up until the incline at the end which is a very short section, about 5 minutes. Overall, would definitely recommend!
