Such a fun hike! Lots of rocks you climb up, it does get steep. It’s not a paved path at all which we loved. It can get crowded at the top with people trying to get pictures but it’s well worth it. We’d do this hike again in a heartbeat.

Awesome trail!

Perfect weather for this hike!! I enjoyed so much by the creek, it is always nice to get a nice breeze by the water. This ended up 8.4 mile hike, enjoyed it so much! 80% is shade, so great for hot summer hike as well. Totally different scenery from hikes around Baseline. Recommended! However this is not "Hard". Should be listed as "Moderate".

Enjoyable hike! Little rocky and challenging at parts, but nothing too crazy. Dog friendly so expect to see a few 4-legged friends out there. Cool views!

Enjoyable, short, and a good exercise. Close to the road in Gregory canyon, but pretty scenery.

Great and challenging hike. Good elevation gain. Was able to do in about 3 hours. Quite a few trail runners, decent amount of wildlife too. Awesome views! You do have to pay for parking on the weekends, fyi.

Very pretty trail. A bit crowded, but not as crowded as I was expecting. I'd call this trail moderate rather than hard, and I'm of average shape. There were parts that were tough, but it's really short so that's why I'd say it's closer to the moderate side. I got to the parking lot by 8 am and it was full. However, there was plenty of parking along the street. It cost 2.50 per hour.

Nice trail but dog are only allowed on half the loop so at the half way mark we had to turn around. There were signs everywhere saying dogs prohibited on the second half of the loop. It was a nice hike with great views. We got a little lost because some it is not marked well but we figured out where we were pretty quickly since I had the All Trails app open.

The road was mainly a dirt road, there wasn’t a lot that was very moderate about it at all except when you turn off the main path and go exploring on the side paths. The views were alright, but I will say there were some slightly challenging obstacles along some of the side trails. There is one in particular that is a dead end and you can see a weather station set up at the top. Pretty cool!

Not too difficult. Finished in under four hours while carrying my 4-month old to the peak and back. Beautiful views at the top! Fun trail!

Great hike. Rated as hard because of the rocky terrain and some mild scaling of rocks but well worth the view. Make sure to pack water as the incline is pretty steep.

I hiked this at about 2 pm and it was about 90 degrees out. I don't think there was enough shade for the heat. You have to pay $5 for parking. I got sort of lost at the end. The path just ends and then another trail starts from left to right so I just turned around and walked back. I guess there's a way to loop around but I decided to just walk back. It was pretty fun and challenging.

Hit the trail at about 7am on a Saturday and it was great, not crowded but started to see more people in the way down, still not bad. Definitely strenuous, but I haven’t done many hikes lately so I’m not sure I’m the best judge. Pretty mellow first half until you climb between bear peak and south boulder peak, easy to hit both while you’re up there and each offers a little bit of a different view so definitely check both out (only adds like 20 minutes I’d say to the hike). Very pretty views and diverse vegetation from top to bottom which kept it interesting. My knees were shakin’ on the way down as there’s lots of rocks to go down but that’s only about 1/2 of the trail, as the first half is quite wide and gravelly. Would definitely do it again!

I really enjoy this trail. It’s easy, breezy and sleazy.

Excellent trail! we did the first leg to the peak about 3 miles. mostly open until you start the climb. Climb was challenging over rocks, right turns. Peak had amazing views. Took Lion's Lair trail back down and this leg was mostly paved but a long 5 miles or so. Overall a really nice park in Boulder with several interesting trails.

Very nice, relaxing hike with absolutely FABULOUS views for no more difficult than it is. Can’t wait to do it with my family so they can experience amazing Colorado scenery without hiking into the back country. Really, really enjoyed it!

Definitely some nice elevation gain with this one! I started at Gregory Canyon and ended on Flagstaff. First mile or so was all uphill and included some rock scrambling. Saw lots of wildlife including a deer. Rangview was also a lovely little hike. Ending with the Flagstaff trail, this is the part everyone speaks of that runs along the road and requires several road crossings. I didn't necessarily find the traffic bothersome but finding the trail after crossing the road could be somewhat difficult, however the alltrails map is super helpful. Would definitely do this hike again! I enjoyed the scenic views of Boulder and the challenge this hike provided.

great short family hike

my go-to hike. not many people and leads to an empty bat cave at the end but very difficult to get to it. views are awesome at the top.

Great trail!

This is a short but challenging hike. Great views along the way and at the top. The hike up will get your heart going. The hike down seemed almost as hard, especially on the knees. There are lots of trails in this area. Pay careful attention to your route to the base of this trailhead as there are several that will bring you here.

This trail is rated difficult for a reason. Tons of large rocks and quick elevation gain. If you have balance issues or are afraid of heights I would say don’t do. The views at the end are fabulous though, great workout! Beware of small area that would almost qualify as rock climbing and not hiking although once you got up wasn’t that bad because of the hand and foot holds they added. Fairly heavily trafficked trail also..

Nice trail. Watch the signs

May hike. Very slight incline but totally doable for my MIL visiting from sea-level. Great views from farther of the flatirons and of the city of Boulder.
