Marshall Mesa Loop - 3.3 Miles Round-Trip
The Marshall Valley, Community Ditch and Coal Seam trails form a 3.3 mile multi-use loop through the Marshall Mesa area in southeast Boulder. Runners, cyclists and families will enjoy mild grades, good trail conditions and rangy views across Eldorado Canyon, the Flatirons and Boulder foothills.
The Marshall Mesa Loop touches the Southern Grasslands Habitat Conservation Area, which protects the largest remaining parcel of intact grassland habitat in the Boulder area.
This tallgrass ecosystem once stretched eastward from the Rockies to Indiana, north to Canada and south through Texas. Today only 2% of its original composition remains, much of it re-purposed by man or overtaken by mixed grass prairie. Mule deer, coyote and prairie dogs are common in these prairies, which also support badger, ferret, burrowing owl and rattlesnakes.
A restored section of Coal Creek cuts across the HCA, where bald eagles and ground-nesting birds return each year to breed.
The following description begins at the Marshall Mesa Trailhead and travels clockwise on the loop:
Head south from the parking lot to the Marshall Valley Trail and bear left (east). The trail rises gently up the open north flank of Marshall Mesa past a large prairie dog village to the Community Ditch - Marshall Mesa Trail split (.9 miles : 5,575').
Bear left on the Community Ditch Trail, which steepens to the Cowdrey Draw Trail junction (1.2 miles : 5,680').
The Community Ditch Trail turns sharply back west and levels on a wide, groomed path atop the mesa with long views across the western plains, mouth of Eldorado Canyon, foothills and Flatirons.
It passes connections for Marshall Reservoir (1.4 miles : 5,725'), the second Marshall Mesa Trail access point (2.2 miles : 5,730') and Greenbelt Plateau Trail (2.3 miles : 5,732') on this mild stretch. The Community Ditch Trail dips to the Coal Seam Trail junction (2.7 miles : 5,737') and turns north on a winding descent through open space back to the Marshall Mesa Trailhead (3.3 miles).

Worth Noting
- Extend your hike with connections to Marshall Reservoir, the Marshall Mesa, Cowdrey Draw or Greenbelt Plateau trails. Be mindful of HCA boundaries, use restrictions and dog leash regulations on each trail.
- The Southern Grasslands Habitat Conservation Area protects a 3,000 acre remnant of grassland habitat in southeast Boulder. Mule deer, coyote and raptors are frequently seen, an occasionally badger and burrowing owls. A restored section of Coal Creek cuts across the HCA. Bald eagles return each year to nest in the cottonwood trees along its banks, and many ground-nesting birds such as meadowlarks and grasshopper sparrows breed here each spring.
- Marshall Mesa earned fame in the late 1800s as one of the most important coal mining locations in Colorado. There were 51 official mines in Marshall, but probably many other undeclared facilities since mines were taxed. The first coal mine was operated by William and Nancy Kitchens in 1859, and sold to Joseph Marshall in 1866. In 1868, President Andrew Johnson presented Marshall with legal rights to all the area's coal.
