Okay. That was hard. A really beautiful hike but if you’re not conditioned (or 6’6”) I would not recommend it. BUT when you get to the arch it is very special and quite the view!

Our first hike in Colorado and it was simply amazing! Loved the view and the rock formations at the peak.

A perfect morning hike. Late start at 8:45 AM yielded a great parking spot! Nice on a weekday AM.

Amazing trail. Great views. What a wonderful hike.

If you’re not used to elevation/altitude, get adjusted first. I did the loop and was winded early though I’m an active/fit person. The climbs were nice with lots to take in. Loved the rock steps on the ascent and descent.

I did this everyday pretty much everyday after my work throughout the summer.

Did the hike this morning. The first 1/2 of the trail is pretty plain and not difficult, but not covered. Once you cross into the shaded area, the incline and switchbacks start. Near the top there are a few places where the trail is not super well marked. Did the base to the top in 2hrs and back down in about 45 min. I started the hike at 6:30am and only crossed two people on the way up. On the way down, I came across about 20 people.

Close to home. Exposed. Recommend hiking clockwise. Very enjoyable hike.

When you get to Sentinel Pass, turn left. We somehow thought the trail went straight. We should’ve noticed this sooner than we did, but we were wrong. This is a beautiful hike with a whole lotta vertical. If you’re looking for a good workout on a shady, well marked trail with beautiful views of Boulder and the Flatirons, and don’t mind sharing those views with a bunch of other fellow hikers, and maybe also hearing the loudspeaker from a CU football game at the same time, this is the one.

Really great hike and view, though it was very strenuous. Expect to take multiple stops along the way. Pack a little lunch for the summit. You’ll want to stay a while and enjoy the views! We clocked 4 miles round trip so I’m not sure where they come up with the 2.5 miles. It’s definitely not if you follow the route listed.

Our family of 5 wanted to do a quick Sunday afternoon hike and this one fit the bill. Our kiddos are 12, 9, and 6- they did great. It was a good Colorado summer day. The trail was a little busy. But not overly crowded. The kids enjoyed climbing on the red rocks.

Saw this "trail" on the way back home, since it's a short trail and get to see the waterfall, I decided to go. Parking space is limited, and also it's by a busy highway. It was such a nice "quick stop". It's worth it! 09/15/2019

Really good workout for a relatively short hike. Not a lot of shade, and pretty crowded which is to be expected for a Sunday morning. Good views of boulder and the front range from the top. Calf burning on the way up and knee busting in the way down! Got lucky with parking but it’s usually pretty full on the weekend morning.

Tough hike. I recorded 4.0 miles RT from the parking lot. The bad news is lots of step! The good news is there’s tree cover right when the steps begin. There’s short scramble at sentinel pass. Nothing too crazy but it can be intimidating for out-of-towners. I saw lots of dogs and a dozen baby carrier backpacks. That’s just nuts. Sweet views at the top.

I wanted a challenge and beauty. I got both!!!

The ranger assured us it was a 2.5 hour hike since we were “clearly in shape.” It ended up taking 3. It was beautiful but definitely challenging - lots of stairs, and at some points the drops were large enough that it was best to sit down and slide off. It does get very crowded.

Did this trail this morning. Great views! The beginning is a lot of climbing. And the summit honestly seemed forever away at one point but I think that’s because I live on the east coast haha. Great workout. Took 3 hours (again east coaster, who doesn’t hike often). You are able to make it a loop with the valley trail, little over 3 miles.
