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.

Outstanding hike! Probably one of my top 5.

We took the steeper side up, and it took a little more than an hour to get to the top. It was worth every step. Lots of beautiful views throughout the trail.

We got a late start around ten; it wasn’t crowded, but it was hot. There are some shady places.

Wouldn’t recommend any kids on this trail. The terrain gets pretty rocky.

Just went yesterday in my STOCK 93 Cherokee. This is a very easy trail that takes you out to a nice roundabout that has a nice hike. The drive itself was super easy and you just need clearance for certain spots, and by that I mean just standard clearance for an SUV. The drive was super nice on the rail and got some nice views of the mtns. It was so much fun I did twice in one day!

Nice mellow route up Mt Sanitas. Longer and not nearly as steep as the Sanitas Ridge route. Popular with runners.

Beautiful tough hike, elevation gain is pretty significant over 1.5 miles. Beautiful views along the way of the Rocky Mountains and over the towns bordering the front range. Took about 3 hours RT

Nature’s version of a stairmaster!

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

beautiful views for a short hike

Good short morning hike, with some rocky areas

Great hike; great views! It is somewhat busy, though. Pack lots of water and expect some rock scrambling.

Difficult as advertised but excellent hike! Will need poles on the descent due to loose rock. The only negative is the trail has been heavily used & eroded so that there are exposed tree roots with 6-10" of space underneath the bottom of the root and the trail. Use caution. Wish I'd known the restrooms at NCAR were open and available on a Sunday.

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.

Beautiful even on a rainy day!

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!

Fairly easy hike; well marked and well worn. Good views of Boulder from the top. Surprisingly crowded for a rainy day.

excellent to get back into riding after the winter months, take it easy and enjoy the view!

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!

Skunk canyon is always beautiful

love this loop and have done it with my dog multiple times. My only concern would be that I don't believe it's only 7.3 miles. my fitbit eve time has put it closer to 8.5-9, just a heads up!

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 moderate trail. Fairly well marked. Good view of town from the top
