    Hike from Chataqua trailhead, direct ascent up and over the flatirons, then to Saddle Rock and back down to Gregory Canyon and back along baseline to Chataqua.

    Sanitas Valley & Dakota Ridge Loop
    Beautiful morning hike. Cool views of the shifting sun light along the ridge. The Sanitas Valley trail was clear with little to no snow. The Dakota Valley trail was covered in compact snow with small patches of ice. Spikes not necessary but would have been helpful in some sections.

    If you don’t have a lot of time and you want to get up in the mountains, this is a great loop. Beautiful part of the Flatirons.

    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

    Pretty strenuous if you’re a wee bit out of shape! But worth every drop of sweat. Great views all along the trail and at the top. Snow/ice absent.

    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.

    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.
