Marshall Valley Trail

Trail Meter: 

The Marshall Valley Trail is fairly flat, rolling along contour at the northern base of Marshall Mesa. Prairie grasses and wildflowers abound in the spring and early summer.  Be sure to rest and enjoy the increasingly stellar views of the Flatirons as you head east along the trail.

The trail is 4 feet wide (or wider) in most places, and along most sections you can see pretty far ahead (and other trail users can see you).  This is a great trail for kids and families.  Although a few sections of the Marshall Valley Trail are raised above the surrounding grade (a type of trail construction called a "French drain"), trail users should definitely avoid this trail during muddy times as the clay surface of the trail sucks up wheels, boots, and hooves and leaves lasting, bumpy scars on the trail surface.

Marshall Valley Trail runs from the Marshall Mesa Trailhead out to where Cowdrey Draw intersects the easternmost end of the Community Ditch Trail.  Marshally Valley Trail is one part of the amazing Dirty Bismark Loop, not to be missed in those warm dry winter days when you're jonesing for some miles.

From FitLiv_BootCamp via Twitter: Marshall Mesa trail conditions. Trails east of 93 ok but a few spots with mud - especially descent from east end of 'canal' #boco_trails

Trail Meter: Poor»Fair

East side of Marshall Mesa ok with just a few spots of mud. Exception is the climb from the MM Valley trail to to trail that parallels the water canal. Heavy clay that has to be walked.

From timschfer via Twitter: Marshall Mesa: some sticky horse-pothole bits, especially Cowdrey Draw, some snow/mud on High Plains, but east side mostly good #boco_trails

From FitLiv_BootCamp via Twitter: Anyone know how the Marshall Mesa trail condition is. Was thinking of biking the east side trails on Thursday [east of 93] #boco_trails

big storm = deep snow, please update this condition when you use the trail, thanks!

From thats_my_line via Twitter: Marshall Mesa, Doudy Draw & Springbrook Loop: few muddy spots but otherwise good to go. Leave the leg warmers at home too #BoCo_Trails
