The Mesa Trail - 13.4 Miles Round-Trip
The Mesa Trail runs 6.7 miles along Boulder's Flatirons and foothills, connecting Chautauqua Park (north) with Eldorado Canyon Road (south). This popular trail offers diverse terrain, multiple trail connections, 4-season utility and abundant wildlife.
Access to Green Mountain, Bear Peak, South Boulder Peak, Mallory Cave, Royal Arch, Fern Canyon and Shadow Canyon provide dozens of destination and routing options that vary in distance and difficulty. The following description begins at Chautauqua Park and travels south:
The hike officially begins on Blue Bell Road, climbing .6 miles and 300' from the parking lot to its formal connection with The Mesa Trail. Bear left for a steady climb through uniform ponderosa to the Kohler Mesa Trail split (1.15 miles : 6,250').
The trail emerges from timber and winds about the foothills' contours with good views east. This mild stretch is interrupted only once by a steep descent down tightly wound, reinforced mud-stairs (1.85 miles).
The trail rises back through open space past splits for NCAR and Mallory Cave (2.05 miles : 6,207'), then drops in a rolling forest to a service road (2.4 miles) - bear right.
The service road climbs steeply past the Bear Canyon (2.7 miles : 6,262') and Fern Canyon (2.8 miles : 6,318') splits before veering (right) back onto single track (2.85 miles : 6,338').
Here the Mesa moderates for 1.5 miles through intervals of dense forest and narrow meadows.
The trail undulates steeply between the North Shanahan (3.25 miles : 6,346') and South Shanahan (3.75 miles : 6,403') splits, then drops sharply to the Big Bluestem Trail junction (4.2 miles : 6,290').
The Mesa continues south, climbing steeply for a short distance before leveling through sparse forest and grassy hillsides. The Mesa Trail passes 3 different access points for Shadow Canyon between 4.35 and 5.1 miles, all of which lead to South Boulder Peak.
The trail gradually tilts down and merges with another service road that begins a long, fast descent through open space to South Mesa Trailhead (6.7 miles : 5,645'). The Mesa Trail connects to the Towhee Trail, Homestead Trail, Big Bluestem Trail and South Boulder Creek Trail on this final leg.
