Quick and easy hike with a beautiful view of Boulder!

I really enjoy this trail. It’s easy, breezy and sleazy.

Excellent trail! we did the first leg to the peak about 3 miles. mostly open until you start the climb. Climb was challenging over rocks, right turns. Peak had amazing views. Took Lion's Lair trail back down and this leg was mostly paved but a long 5 miles or so. Overall a really nice park in Boulder with several interesting trails.

great short family hike

May hike. Very slight incline but totally doable for my MIL visiting from sea-level. Great views from farther of the flatirons and of the city of Boulder.

An amazing view of what Boulder Colorado has to offer. A must see hike!

Really a walk, not a hike. Bob stroller friendly.

Great hike awesome view from the arch. steep in places and rocky. worth the trip.

Quintessential Boulder hike. Went clockwise today - I prefer to tackle the big “steps” on the ascent and come down through the valley. Always nice to have bathrooms (across the street from the trailhead.) Friendly faces and interesting terrain. A perennial favorite.

I do this trail every Saturday morning. It's a nice little hike through the woods, just no real payoff..

Nice, short trail for a quick nature getaway. It is quite steep if you enter from Settler’s Park, much more than expected. There are beautiful views of Boulder at the top. Bring lots of water and sunscreen as there’s not much shade.

Great trail. Lots of climbing on the way up, but it’s all worth it for the views at the top. Go early to avoid the crowds – it was already pretty busy at 7am and people were lined up inching along the narrow paths on on the way down. Free parking is available about 10 blocks away.

Great morning hike! Took me 2 hours with a 15 min stop at peak.

Certainly challenging, but nothing to lose sleep over. Expect to wait in line if you’re hoping to get decent pictures at the top.

"Stairmaster Sanitas" is a great place to get a very real workout in. We are in decent shape and climbed up Sanitas and went back around the valley loop trail within 2.5 hours. I would categorize this as "moderate to hard" given a few of the rocks you have to scramble over and how steep it is. While you can carry a child on a backpack up an down, it's not the greatest one to choose for that since you might have to shuffle a bit over rocks, etc.

This is definitely a “hard” trail, bust super proud when I finished! Practically all up hill on the way there but that means down hill on the way back! The views at the top are beautiful! I would recommend starting it sooner rather than later so the traffic is low and the sun isn’t too high!

We enjoyed this hike! It was definitely a high incline and rocky but it was worth it. It was a bit harder then expected the the views are beautiful and the arch is pretty neat. Bring lots of water, take stops and enjoy the outdoors! There are trees on a lot of the hike which gives some much needed shade every now and then.

Thought we would start here on vacation to get used to the elevation before heading to RMNP but this was a tough hike for us. Arch bigger than expected and nice view of flatirons

Enjoyable, no one in the trail today even though it is Saturday, maybe because it was hot! Steeper climb if you go counterclockwise. Good day, will do it again when it cools off.

This was a very nice short first day hike for our CO vacation to get acclimated to walking at this altitude/weather. I would put the overall difficulty more towards moderate, but it’s a tough call as parts are easy, parts are moderate, and there are some steeper stretches that are more difficult. We went relatively early on a July weekday and the number of people going up was not bad at all, but we passed a ton of people going the other way as we can back down. Yes, bring water, wear good hiking shoes, sunscreen, etc and otherwise use common sense. Although short, the trail has more of the feel of a “hike” than a walk in the park.

Good one

Easy trail with amazing views of the Flatirons.

Beautiful views from the Royal Arch and worth the effort it takes to hike up! Would not recommend this trail for small children, elderly, or dogs that are not experienced hiking companions in high altitudes. Very steep, rocky, and mostly vertical climb. Several areas require scrambling. You’ll want a good pair of hiking/approach shoes. Do not take this trail if you have bad knees, hips, or ankles. Otherwise, enjoy!

loved this trail. lake and mountain views all around.
