Great hike! Had to take breaks but the view at the top of the trail was amazing!

On point, I recommend starting by 730 if you want a good pic without others in it and close parking. Lots of shade. Wear good shoes as the rocks are sharp in some areas. Took about 2.5 hrs with the need for some breathers.

Great morning hike with superb unique views, friendly squirrels, a few steep spots, and nice shade.
It can be hard to find the actual 1st and 2nd Flatirons trailhead if you're not familiar with the area - just follow the crowd up any of the trails (such as Chautaqua trail), and you will be led to this trailhead.

This hike is mostly easy with a few very strenuous hands-and-feet areas. Final elevation is about 7,180. I'd rate it moderate.

Definitely Challenging, great views at the top and shaded most of the way up. Often crowded at the top.

Easy to navigate, challenging and great view at the top.

great hike! arrived Saturday the 7th at 610 am still plenty of parking. starts out easy and turns mid hard including some rock scrambles at the upper levels. beautiful birds singing and flying around much of the hike. we went off the flatiron 1/2 trail and did some improvisation until we got to an area that got to too technical and turned around. went back to the trail and the upper level is a lot of switchbacks. beautiful views all the way and the top was a nice reward. big crowds were flowing in when we were leaving at 1030. go early!

My husband, 12 yr old twin boys, our dog and I did this trail today. Lots of people. Very friendly. The trail could be marked a bit better but we had a great time!

One of my favorite hikes. Beautiful and fun! you will see definitely be able to see wildlife there. Expect a bit of climbing. Great view at the top.

A great, easy trail with a gradual, gentle elevation gain and beautiful views. It is a multi-use trail shared with mountain bikers and horseback riders. If you are a hiker or walker, be prepared to yield for them. At times the trail is narrow, so passing one another can get tricky. I'd recommend forgoing the headphones so that you can hear bikers coming behind you. The day I went everyone was polite and respectful while navigating the shared trail.

My wife, son and I did this today. Outside of being hot, the trail was great. A lot of folks on the trail and a bunch at the arch itself taking photos.

This is a really nice trail if you're looking for a relaxing walk or hike. Paved and gravel paths are often used by cyclists, but a dirt path runs along a creek for walkers and trail runners. It's a popular trail for families with young kids or people with their dogs, but it never feels overly crowded. In spite of being on the east side of town, you still get nice views of the Flatirons along the way. The parking lot on Baseline is pretty small and fills up quickly, but if you park at the East Boulder Rec/Community Center, you can connect to the Bobolink Trail.

Very fun trail. Worth the tough parts for the view at the end! We had two dogs with us that were able to complete the trail as well.

Great hike with spectular views, but it is strenuous.

Tons of off leash dogs. Pretty trail otherwise.

Beautiful but really difficult! Lots and lots of stairs! We started at the NCAR parking lot. From the parking lot to the Arch and back was 8 miles.The trek from the official trail head of Royal Arch to the arch was pretty tough. Great views though. and LOTS of people. We started at 9 am and there were a ton of people out and about on the trail even on a week day.

Great hike at moderate to hard difficulty. Go as early as possible. I started at 7am and there were only 5-10 people on the scenic top. Apparently it can get up to 50 people in the afternoon.

Love this hike! I've done Royal Arch 20+ times, and it never gets old!

Awesome views! Harder than we anticipated but worth every step we took.

Great hike, definitely tough! Lots and lots of "stairs". View at the top is totally worth it Go early, we started at 7:30 on Saturady morning and as we were going back down, the trail was packed with people heading up.

Proposed to my gf at the Royal Arch, beautiful view that shouldn’t be missed out on!

Difficult, but the views along the way up are beautiful - can be hard on the joints and toes, also slippery when wet.
You can see the Denver skyline on a clear day!

Great trail not too crowded and great views on the way up, the top is the reward.

Very heavily travelled trail, the view is worth it, but go early. most hikers get to the Arch and hang out having lunch etc, so it is very crowded at the top.

Beautiful view of flat irons and boulder at summit. Bring lots of water for ascent.

It’s not that hard as these people saying!!! Not 3 miles, 1.8 miles in! It was pretty easy for me and my 3 months old puppy mini Aussie made it like it was nothing!! No more than 2 hours in and out, not even 4 miles in total!

Good, challenging trail. Nothing too crazy, but you will definitely get a workout in. The trail is heavily trafficked and narrow at points. When getting closer to the top the trail gets rocky and you go down and then up again. Even though you go down, you still have a bit (maybe about 20 minutes) to go, so don’t be surprised - you’re not done climbing yet! Views from the top and the arch are beautiful. Worth the climb.

We started this hike at 7pm, did it clockwise (via Saddle Rock) and hiked in complete shade, as other reviewers suggested. It was pretty tough to start. I would say it was about 45 minutes to the top, but honestly, I didn’t realize we were at the top when we got there so I didn’t check my watch! If you go clockwise be sure to stop and take in the views on the ascent. Those are the best views of the beautiful mountain range. You don’t get a grand view at the top so stop and enjoy while you ascend. After reaching the highest point, the trail is a lovely walk through the woods mostly on a gradual downhill. Our total trip was just over 2 hours and we were in no particular rush. Very light traffic- only saw 6 other hikers.

My husband and I were prepared for a hike and wanted to see flat top but it was closed so we chose to take the royal arch trail on the spot. We had two 1L bottles of water and needed more! Stopped several times to catch our breath. Granted we’re out of shape. But if you’re not at least moderately active this will be a tough trail. The view up top is worth it if you’re prepared. I would only take a working class dog up- I saw a few people with small dogs and children and felt bad for them.
