Very nice hike. Sort, so added some additional trails in the Chautauqua area. Left at 8 and had reasonable traffic on the way up. Very busy on the way down.

Nice trail, not far from homes. Good, steep ascent. Added Red Rocks trail to make for a 4.5 mile hike.

Added it on to the Mt. Sanitas loop to make the hike longer (4 1/2 total). Nice way to start. Parking lot had plenty of space at 8 am.

Awesome trail with a nice surprise at the top! Good cardio incline at the beginning, middle levels out for you to catch your breath, and then a steep incline at the top. Well worth it tho!

Great hike for families. Took our 5 year old and 1.5 year old (in carrier) up this trail and they loved it. Going up McClintock Upper is definitely the more challenging direction for this loop as it's pretty good incline until you reach the Enchanted Mesa trail junction. A few good views, but it's really a nice stroll through the forest and across the Enchanted Mesa. Many trail runners and people walking dogs.

Really nice and amazing view

Awesome hike!

Hiked on October 19th. Trail was great. A little steeper than I thought but an awesome hike.

Amazing. As good as it gets!

Hiked this trail yesterday evening. Encountered a few slick areas, but very manageable, even without spikes. Took 2 hours there and back.

This is a lovely hiking and MTB trail. I had no issues sharing the trail with bikers as they were all very friendly and courteous. The views down the valley are gorgeous, especially in morning light. The Wapiti/Ponderosa/Wild Turkey Trail loop was easy/mod with sure footing and well-kept trails. I came across two handsome 8 point bucks on the north side. Nice views of Meeker and Longs Peak. Plentiful parking and vault toilets at the trail head. A real gem!

a few too many road crossings for my taste. saw plenty of mule deer towards the begining of the hike. got a bit slippery with ice and snow which made it slow going.

Well it was super icy today but it sure was easy if you have spikes on your shoes! Slippery for sure but if you’ve done it before you know to just keep pushing. If you haven’t done it before.. well, keep pushing! Beautiful fun tough work out. I always take the 1st and 2nd loop, i even took my parents from Texas in today and we finished it in 4 hours... beautiful in the snow if you ever wanna get it :)

Great hike. More challenging than I thought especially attempting it immediately upon arriving from the east coast. Well worth it once you get to the arch.

Great hike, but beware that it is very slippery and icy with the recent snow. I underestimated how slippery it would be on the way down and I fell several times. Definitely come prepared and watch the weather before you go!

lovely trail with a noice rock at the top pretty busy though

Nice difficult trail......great workout and view at top! Very good local hike.....

Difficult but great view at the end!

Short loop around main base area of Chataqua. Great views of the flatirons all around

Flatirons are so beautiful and such a classic hike

The long way to get up to Flagstaff summit from the base of the canyon. Climb up gregory canyon then cross the road where there is parking just off flagstaff road if you'd rather start with a smaller amount of elevation to climb.

Great loop around Chataqua through open fields and a bit of the forest

There are many routes to the top! be aware when you finish the switch backs that run doing the creek there is a false summit. Go past the trail marker and you'll have to head down for a little bit before a short climb back up to reach the Arch.

It was pretty busy today. There were lots of dog walkers. The weather was great right before the snowfall expected tonight. Terrain was pretty easy - an occasional big rock jutting from the trail but not bad. Great views though!

Challenging for a recreational hiker & worth it - beautiful views, the arch did not disappoint!

Never did find the trailhead; used the AllTrails map link.

The loop we followed was Chautauqua to Meadow to Gregory Canyon to Ranger to the summit of Green Mountain to E.M. Greenman to Saddle Rock to Gregory Canyon to Meadow - almost 10miles. Very strenuous on the way up, took almost four hours to summit - we are not from this altitude. Absolutely stunning and worth every grueling bit :)

Amazing trail very well worth it

nice short hike
