Impossible without spikes. The trail is ice the entire way. On the plus side, the views are awesome, and we were the only people on what is a normally very busy trail.

beautiful hike, but always very crowded. went with a horticulturist and learned a lot about the various medicinal native plants.

hiked this a couple years ago and remember really enjoying it. the scramble at the end of difficult if you're not comfortable with this kind of terrain. saw lots of people and dogs. I found it a tough trail to hike with a leashed dog. beautiful views!

love this hike! have completed it a couple times. great to take out of towners who want to see our beautiful canyons, feel accomplished, but not terribly difficult. lots of areas to stop and enjoy the views. fun seeing the rock climbers throughout the canyon. interesting history with the hotel ruins.

Really great views of Boulder. Definitely an asskicker at times, though not always. Trail was in good condition, with lots of people taking advantage of perfect hiking conditions.

A great short hike. A little icy in places after snow.

Beautiful hike! There are still some patches of snow/ice/water, but not a problem with hiking boots. Ran into just a handful of hikers and runners.

I love this trail. I completed it last month before the snow. The nature and views are beautiful. I loved watching the train pass in the distance. I am a Colorado native so I never really feel inclined to go back to most trails but I will definitely hike this trail again. There is an $8 fee to get into Eldorado State Park, or $5 to park outside the park and walk in, but you can tell the state park puts the money to good use. This has to be one of the cleanest trails I’ve seen. There aren’t too many tactical areas. I went counter clockwise at the loop, so going down the incline back to the trailhead was rather rocky and steep. I almost fell at one point, but it was only for a short stretch.

The definitive Boulder workout. One of the first to try if you are only here for a short while!

Trail was closed today. Hiked this before with my dog and she loved being off leash with the cows. Special dog tag for voice control needed for off leash capability.

There are rattlesnakes so be careful, but don't miss out! This is a great workout for people looking to improve beginner hiking skills. Lots of great views, really cool area for rock climbers, and a little history hidden on the trail.

Tough trail for beginners. Definately a good workout. This is also a very popular trail.

I would have liked to pick up the pace to get a better workout in, but the trail was pretty crowded (granted, it was midday on a Saturday.) Overall it was a nice trail, great views at the top, and fun to watch climbers on the opposite rock face. My friends and I maintained regular conversation without much huffing and puffing and there were plenty of kids on the trail, so I’m not sure if deserves a “moderate” categorization, but it was a great outing for sure. Saw some cool birds, too!

Lots of snow this morning! Make sure you are prepared if hiking in the snow. About half the trail I was second person then almost all of Flagstaff on the way back down was breaking trailhead. Snow ranged from 2-3" to about 8"-10" deep at points. Waterproof boots are a must. I did wear spikes but didn't really need them for the most part. Not a ton of views due to currently snowfall. But there were several spots where it was still very pretty despite minimal views. I would def do this trail again when it isn't snowing. Worth the hike for sure.

Great trail without a lot of loose rock and fairly easy footing. Steady inclines and great views made the hike really enjoyable. Parking can be a bit tough but the hike is well worth it!

Great trail and beautiful views.

got there at 10 a.m. yesterday only a couple of cars in the lot. though there's not a lot of spaces. well maintained trail. nice steady incline for first couple of miles. the view at the top was beautiful! bring layers! started off needing 2 jackets a hat and gloves went down to just day clothes as we got going.

Nice wide beginner hiking trail with a few steep area but nothing to drastic. There are benches along the way so you can take a breather if the trail gets you a bit winded. Today was a perfect day with clear blue skies but the at the Overlook the wind did have a slight bite. The snow capped mountains in the distance were amazing to view. Would like to do this trail again in the spring to see the wildflowers.

Beautiful trail with some nice views near the top. The Flatirons are really cool-looking peaks! The trail is really well maintained and manageable to walk on, even during the steeper points. Lots of switchbacks toward the top made the ascent easier than I anticipated. Only one very brief scrambly section.

We stopped at the very top of the second Flatiron (the trail seemed to peter out a few meters behind it) and came down via Bluebaird Trail. Passed lots of other people in the morning, but no congestion.

Amazing fog this am with snow flakes. Trails dry with friendly people and amazing views. Happy Thursday m8y's Oiiiii

Plan to park on the street. Hikers quickly move away from the residential area and into more natural surroundings. Maintained trail scattered with rocks, for a more rustic feel. Morning sunshine shows off the mountains the best! We saw a few people, but mostly had the trail to ourselves. Gorgeous views. Loved listening to the wind course through the Lodgepole Pines!

Short and steep, a good workout, with some good views. Not so crowded, but it was a weekday in early November.

great hike. took the kids 3&5. I would say this is a moderate hike only if you are doing the final climb to see the cave entrance.

Awesome hike. Not overwhelming hard but tough for moderately in-shape folks. Mostly climbing steps. Gorgeous view at the top.

Great hike! 'Moderate' rating is appropriate. Signs and trails can make it a little confusing at the beginning, so following the mesa trail signs not the ncar trail signs. It's a pretty steep hike in general. 2.4 miles OUT and 2.4 miles BACK. Last 100' was too steep for our group of 2nd graders. Beautiful views amongst the flatirons. Still worth going even though we could see the cave at the top.

Lots of steps up (45 min) but worth the reward. Easy hike down.

Trail was not super tough. I would highly recommend using spikes. I did not and was fine. Just watch where you’re stepping. Though my wife did use spikes and said she felt much more comfortable coming back down. There was an incident with a dislocated hip. Not sure if it was from a fall or whatnot, but it is better to be safe than sorry. As you get further up trail you run between dry land/rocks and icy areas. The end is def worth the hike up. Just be careful!!!

Awesome hike. Leg burner for sure!

Great views of Boulder. Decently trafficked by people and easy to find the trail. Around the peak it does get pretty rocky so good shoes and sure footing is highly recommended. Haven’t hiked in awhile and did the loop in a 1 1/2 hours with a longer break at the top.

Gorgeous trail. Strongly disagree with the "hard" rating-- it's difficult for a relatively short period of time, so I think it's more in the moderate category. It was actually rated moderate on alltrails until about a month or two ago.. not sure why it was changed.

This trail is short, energizing and has better views than some of the even harder trails in Boulder.
