Great hike with spectular views, but it is strenuous.

Great views, nice variety, good workout, a little confusing a couple times as the trail name changed. Would recommend.

Tons of off leash dogs. Pretty trail otherwise.

Easy to navigate. beautiful scenery. no shade at front end from NCAR. but once you get going there is eventually shade. Lots of wild flowers, butterflies and bees.

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.

Nature’s version of a stairmaster!

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

Hmm... all trails is off!!
1. It’s 10.53 miles
2. It’s not hard, more moderate. If you’re out of shape, then it’ll probably be a little hard.

Definitely a workout (step-style over rocks and roots in the canyon), but worth the views! Also quite easy (once you’re up there) to shoot over to Bear Peak. A lot of sun on the meadow trail area until the ascent, which is shaded for most of the canyon until the switchbacks leading up to the crest splitting the trail between South Boulder Peak and Bear Peak. Had to push myself a bit, but loved the vistas! Best to do on a weekday. I can see how it may get crowded. Barely anyone around today (Monday).

Parking is close on the side of a big bend in the road making it a pretty dangerous spot with cars flying by so be careful. Short easy walk to a roaring falls!

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!

This hike is a killer workout - I call it my "summer butt" workout. Basically stairs for the entire ascent. In early June, we started around 9 am and it very quickly turned HOT. It was also very crowded. We spent a lot of time leap frogging and moving to the side to pass or be passed, hence the 4 stars. That said, as far as Boulder hikes go, this one was great. Tons of wildflowers, dogs allowed off leash, and some satisfying views of the front range from the top. My dog and I did the quick ascent up Bear Peak, but the bugs were so oppressive we couldn't even enjoy it. Will also warn folks that my dog, a year old 40 pound labradoodle, has done multiple ascents and I brought plenty fo water for him. We saw lots of dogs that were way overheating on this hike, so bring extra water to drench your dog. It's nice to do a 3k ft ascent within a 30 minute drive of Denver. Will definitely be doing this again!

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

Beautiful, short hike with 9 year old. Half shade and half exposed. Elevation gives it a good workout.

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

not challenging but a nice little meander and pretty views, nice place for a quiet afternoon or lunch, fine for kids and dogs.

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.

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.

I actually start this near Saddle Rock (off Flagstaff), go up Ampitheatre and then back down saddle rock. Doing it that way knocks off about 3/4 mile but makes it a great short but strenuous hike - I clocked about 1200 feet elevation gain- and a nice weekday workout. It is mostly a shady hike making it a good one even for hot summer days. Some water most of the year as well for dogs on the Saddle Rock side.

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

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.
