    1st/2nd Flatiron
    5/31/2025 Late morning start, temp in upper 70s, sunny and clear with great visibility. Couldn’t ask for better conditions. Don’t forget sunscreen. Took our miniature dachshund and went at a leisurely pace chatting with visiting family. Trail was clear and well-maintained as always. Really not a difficult trail if you are in decent shape, somewhere between easy and moderate.

    Track (9/25/22, 5:42:43AM)
    Super fun! Left before sunrise to try to make it to the top by sunrise but overestimated my speed. I don’t hike very often so my speed is just under average. It took me just under two hours to go counter-clockwise to get to get to the top. I’d definitely recommend going clockwise, my knees are aching at how steep the downhill was! There were a few scrambles across flat rock, but most of the difficult part was large “steps” made from rocks. Overall super fun, and I’ll definitely be doing it again.

    Accent is pretty tough but the view up there is spectacular. Once you’re down the backside, probably 400 feet drop in half a mile, the rest of the trail sort of rolls you home.

    1st/2nd Flatiron
    This is not an ray hike. “Moderate” as NPS marked it on the signs is a better description. The trail has a good incline most of the time and once it veers off the Flatiron Loop it include a rock scramble. The views are Ok, pretty crowded on the weekend

    Good hike for winter exercise. Best views are at the start. Trail was mixed dirt, rock and ice - bring microspikes if uneasy on compact snow / ice.

    Green Mountain Loop
    This was the first hike I have done in Boulder. The trail is nice, but was a little snowy and muddy after the recent snows. The view from the top was alright, but nothing amazing given that it was reasonably difficult. Doing the loop clockwise was nice and I would recommend it. We didn't come across too many people after leaving the meadows on a sunny Friday.

    Bear and South Boulder Loop (7/22/20)
    A bit steep toward the summit, but nothing unmanageable. Nice views at the top looking out towards the mountains and back on the city. The extension to South Boulder Peak added a wider vista for views and pretty easy out and back.

    Love this hike! Fern canyon and the upper ridge to the summit unrelenting, but this is a great hike for flatlanders (like myself, from Florida) to start acclimating for bigger mountains in the area.

    You can’t hike Boulder without a journey to Beat Peak! This is a great rout starting in Shanahan Ridge. It’s an up and back, with a challenging climb, but the views are spectacular!

    Royal Arch Trail
    The first part was paved and slightly uphill. It eventually got you to the Royal Arch trailhead. From there, it was very challenging. Terrain included very rocky trail with steep sections of uphill scramble and downhill as well. Hiking poles recommended. Excellent view from the top and Royal Arch is beautiful.

    Moderate hike through open grassland and prairie dog towns along valleys and mesa tops. There are a lot of options of other trails to make this hike shorter, or to add on. Great views of the plains and foothills from the high points. The Mesa Reservoir provides some interesting birding. Dogs are allowed off leash on this trail as long as they have a Boulder Voice and Sight tag.
