Fun, intermediate mountain bike ride about 20 minutes west of Denver, near Lakewood, Colorado. This trail is fairly easy with a good climb and intermediate descents.

Good trail. Little tree cover and some heavy traffic at the start but thins out as you go. Watch for the mountain bikers though: a bit unruly on this trail.

Went up the steep climb to complete a 2.2 mile run to the cell tower and back down. The traffic is usually light, but can readily become heavy with runners and bicyclists.

Nice, steady uphill grade. Fairly wide trails making passing other hikers easy. Overall, the hike was pretty easy. Go during the weekdays to avoid crowds. The summit loop on the northside can tricky for those with bad knees coming down (steep in a few spots with lots of loose rubble).

Trail is in great shape. Perfect trail running location for accessibility to the front range and for views of the city and Red Rocks

First timer. Enjoyed doing something new and loved the scene. Weather was perfect today @75 and a nice breeze. Next time I'll do the who loop. Parked on W Alameda at the dog park and took off. Enjoyed this. Walked and jogged this trail.

Really good running trail, but is along the highway, so it's not an exclusive nature type trail. Really great workout

Easy hike, great views, beautiful wildflowers. Saw lot of 3 leaf sumac right near trail head. Lot of milk vetch, purple vetch, ground purple vetch, chiming blue bells, golden banner, whisk broom parsley, chokecherries and many more.

Great terrain variances, for a trail run anyway. Went up a couple days after some snow, and it was a little soupy. Lots of mud throughout and snow closer to the summit. Dangerous downhill running when you can't see the rocks underneath! Lots of different options. Just make sure you familiarize yourself with which trail you want beforehand, otherwise milage is all over the place. Also, enter from Alameda, so you don't get stuck in the hills of mansion-filled culdesac and private entrances.
