The Lower Big Bluestem Trail is just one of multiple trails around South Boulder Creek off of Highway 93 good for hiking, trail running, etc. This is a great area to enjoy Boulder without driving far. It is great for an easy and casual hike or trail running. Due to the 2013 flooding, some of the trail is still heavily gutted and may require some zig-zagging.

Mesa Trail part of this loop is closed Mon-Fri for trail repairs through December. So currently it’s an out and back.

$5 Parking for non boulder residents. Rumor is they ticket so bring exact change.
Once you get a mile in very narrow overgrown path. Make sure to wear long pants as foliage will swat your legs non stop. Very rocky terrain and flat for most of the trail. Tons of wildflowers.

Agree with Sean A. below. Went on a Friday and only saw 7 people. Did the whole loop plus Greenbriar Connector which was where I started because the Skip Bus drops you at the trailhead. I think very early spring or fall would be most picturesque for this walk. Mesa Trail is being flood mitigated along this bit, so workers up there. Good conditioning and peaceful on a weekday. Might be a nice snowshoe.

This trail was fairly disappointing. It is in an open space with no trees for shade and nothing of note to see along the loop other than the backdrop of the Flatirons. It's probably best as an exercise trail, however the South Boulder Creek Trail is very rocky most of the way, which is not ideal for jogging, and for the $5/day parking fee I would have hoped to find the trail more cleared of the rocks.

Important note: there are several cattle gates that need to be opened along the way and toward the end of the hike the herd was literally blocking the last part of the route. The people I was with were very hesitant about walking through the middle of the herd, so I led the way, but honestly it was a pretty sketchy trying to walk my dog through the middle of a cow herd with him being excited to see cows, curious calves excited to see us, which led to a protective mother cow to briefly charging us. However it turned out to be the most interesting part of the hike.

By the looks of it they may be building a road to the base of the Flatirons which would be a nice way to get straight to the mountain and avoid this trail.

Way too muddy right now.

Dogs only allowed from one side, so check before coming with FIDO. Pretty views of Devil's Thumb area, easy walking, rolling hills

Pretty views on an easy trail. Very little, if any, shade. Saw lots of different types of butterflies. Only saw a few other hikers on this trail. Connects to several other trails so you can adjust your distance.

I started this hike from the El Dorado Springs parking lot. It's a good after work hike. Nothing spectacular; not difficult. Nice stroll.

It would be 5/5 if I didn't have to pay 5 dollars for a trail I grew up hiking on.
