Gorgeous hike. Can be heavy traffic on the weekend but still not bad. The view is worth the hike.

Beautiful day on the trail. Even though this is ranked moderate it’s a tough one. The views from the arch are incredible.

Good trail, had a little bit of everything- slight inclines in open areas to rocky climbs in the trees. Great view from the top!

An easy, pretty trail. I particularly enjoyed the wildflowers around the lake.

Awesome hike! The climb was a fun challenge. Be ready for a crowd.

Great day for a hike. Beautiful park. A bit too crowded for me. I got here early so parking was not an issue but there are not a lot of spots to park.

Great hike, although a little crowded on the weekends.

I LOVED the flatirons! This was my first hike in Boulder as someone who was traveling from out of state. The elevation definitely makes this a bit more challenging, though I would say I struggled more with walking the inclined trail than the rocky terrain. Some of the areas were pretty challenging while others weren't so bad. Wear good hiking boots/shoes and you'll be set! The view from the top was fantastic.

I decided to have an impromptu sunrise breakfast overlooking Denver. This trail provided a pretty nice spot to welcome the new day. I started before sun up on a Tuesday morning so I was the only person on the trail. I followed the Red Rocks trail to the Morrison Slide trail and did the loop clockwise. It was pretty easy with only a few sections that required some high stepping. If you live in the Denver area and you are looking for a quick hike with a view of the sunrise, then give this one a shot.

Easy beautiful trail. Views of the red rocks are amazing.

I don’t understand why this is rated hard and Sanitas is rated moderate.

Very rocky and in some areas eroded. Nice tree coverage. For the most part a lot of incline... up up up! Heavy traffic on the weekends, lots of families and dogs. The parking lot was full by 1 PM on Sunday.

Great for toddlers and carrying babies (no strollers). Busy on the weekends, but not crazy. Definitely worth the time for a fun family afternoon hike.

One of my favorite easy hikes, usually busy though.

This was a very rewarding hike—lovely views and comfortable tree cover almost the entire way. But I would rate moderate rather than easy, and while my 6-yo (an experienced hiker for his age) tackled the elevation gain fine, our three year old needed lots of assistance. I’d call this “older kids” friendly and not “all kids” friendly.

It feels like 18,000 stairs. Moderate? The view at the top made it worth it. Very challenging hike. It was not crowded at all but the parking lot was full.

Have done this hike multiple times. Short but challenging as it a pretty consistent climb. The trail is clear of all snow and ice at this point. The nicer weather has brought out huge crowds lately, so go early! I had the top to myself today for several minutes around 930 AM. Great views at the top!

Moderate/difficult but totally doable. Heavily trafficked but really beautiful and worth it.

Scenic hike but very short. Visit the amp if you haven’t visited before

Great trail for a half day hike. View is awesome. We added the Flatiron loop on the way back.

I was thoroughly surprised with how much I enjoyed this trail. It was much more difficult than I anticipated, you’ll definitely get your heart rate up. But it’s worth the climb. It’s very rocky most of the trail which my pup and I loved, but I did notice a couple older ones who struggled climbing a bit in some steep spots.

Fun and currently in good condition. View at the top is tough to beat.

One of my absolute favorite hikes during the week and in the off season. During the warmer months and on weekends this drops far down my list with the amount of people on the trail. This is definitely on the higher end of the Moderate scale if not straight up Hard. This was slippery from when I went last October to this past week in April. Definitely recommend spikes or crampons, saw many people fall on their backs. The view from the Arch is beautiful and a great place for a rest and picnic.

A great & intense little hike for a long lunch break (2hrs) in the middle of the day. Definitely one of my top 3 favorite hikes in Boulder.


Great elevation incline in first stretch and covered winding trailed going up. Beautiful views from top, as well as solid rocks!

No snow on the ground and amazing views 50% throughout. A good challenge on the elevation and incline. Plenty of room at the top to hang out and continue exploring.

Loved it! Fun and challenging with excellent views!

Nice late afternoon hike with my baby, quiet despite being close to highway. Beautiful scenery and easy access to the creek to dip your hands or feet.

Perfect day hike for when someone is visiting that enjoys a bit of a challenge.
