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.

Awesome trail! We started on the East side of the mountain and went up Dakota Ridge trail. It was a nice hike but very hot outside starting at around 9 am. I would suggest getting there earlier and bring water.

Easy to navigate, So beautiful! Lots of parts that are great for trail running.

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.

Go early in the morning. We started at 8 am, but by the time we were coming out it was starting to get too hot for the dog. There is some shade, but the middle part of the hike is fairly exposed to the sun.

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.

Good trail, some parts were really hard.

Great trail.

bring more water, thats for sure! the trail is really hard. once you reach to the top. its its worthy

We started this hike just before 7pm and made it to the top in exactly 1 hour. The trail is very well marked so we had no trouble finding our way. We did The Valley side up (also well marked at the trailhead) and the other side down (40 minutes to descend). The Valley side seems a bit longer since it starts very gradual and leads to a steep incline for the last 3/4 mile or so of the hike whereas the other side is more of a direct route. The views are well worth it, especially for a trail so close to town. Although we started late there was a decent number of people on the trail. Many trail runners too. I assume we hit it at a time when the traffic was modest though. I’ll be repeating the hike in the opposite direction just to give it another go. Very enjoyable and a workout!

Definitely a harder than most hike as it is a pretty steep incline. Beautiful views at the top. Get there early!!! The trail is literally packed after 10am and it is way too small to accommodate that many people.

This is a beautiful trail but it was not in any way “easy”. It was the first time I took my dog out hiking and it was very challenging for him. It’s a nice hike with beautiful views but there is a lot of climbing up and down and rocks to climb so just be aware. It was also easy to get lost- using this app saved me!

This hike was difficult but so fun! Beautiful hike close to Boulder, with great views in all directions and some great birding opportunities. Definitely recommend to anyone because it’s no too long and you can take your time even through the steep stuff. The only thing is, being so close to the front range on a hot day it is very hot up there too.

This was a good hike, seen some deer on the trail and beautiful views.

Loved it but hot in the summer! Partially shaded

Went on a Monday morning and seemed to avoid the crowds. Beautiful hike with a few tricky spots towards the top. Wear good shoes, bring lots of water.

Great Trail paths are easy to navigate not to hard for beginners just wear proper shoes for traction.

I haven’t done any hiking in a while so I fully agree with the ‘hard’ rating. Personally I would wear shoes with ankle stability because of all the loose rocks, but doable in sneakers (that’s what I was wearing). It was a pretty busy trail but mellowed out once you get off the paved portion. The view at the top was breathtaking!

Challenging hike but fun and view is worth it at the end. Bring lots and lots of water.

Great, easy trail. We started late around 2:30 and finished before less than 3 hours. We took our time at the start to acclimate to the altitude. Arrived in CO yesterday.

Somewhat challenging hike. Pretty views but so overrun with tourism I don't care to go much anymore
