The Walker Ranch Loop is one of Boulder's most popular multi-use trails, open to hiking, running, biking, fishing, horseback riding and pets. This 4-season loop is notable for its spacious rolling hills, interesting rock formations and rich wildlife. The Walker Ranch Loop is comprised of 4 distinct trails:

Columbine Gulch: (1.62 miles)

Eldorado Canyon: (0.93 miles)

Crescent Meadows: (2.4 miles)

S. Boulder Creek: (2.6 miles)

3 main trailheads access the Walker Ranch Loop:

Crescent Meadows Trailhead

South Boulder Creek Trailhead

Ethel Harrold Picnic Area

You can also reach the loop from Eldorado Canyon State Park via the Eldorado Canyon Trail to create a much longer and challenging 13.6 mile route. The following description begins on the Columbine Gulch Trail from the South Boulder Creek Trailhead and travels clockwise:

The rugged trail climbs .85 miles to a 7,300' ridge with commanding views, then drops rapidly along a series of shaded switchbacks to its connection with the Eldorado Canyon Trail (1.62 miles : 6,795’). Turn right to continue the loop on what is now a wide fire road (the Ethel Harrold Picnic Area and parking lot is just .25 miles to the left on this road).

The fire road runs up, then down for .93 miles to a seamless but well-marked merge with the Crescent Meadows Trail (2.55 miles : 6,495’). Bear Right and merge onto the Crescent Meadows Trail (bearing left and continuing on the Eldorado Canyon Trail would leave the Walker Ranch Loop and take you into Eldorado Canyon State Park).

Now heading southwest, the Crescent Meadows Trail crosses over South Boulder Creek (6,465'- the Loop's lowest point) and follows a very steep, rocky footpath and series of newly built steps to a narrow ridge top (bikers will need to dismount). Smooth trail conditions and pleasant scenery mark the next 2.2 mile, 700’ net climb to the Crescent Meadows Parking Lot and South Boulder Creek Trail connection (4.95 miles : 7,345’).

The South Boulder Creek Trail drops steeply for 1.3 miles on winding switchbacks through dense pine forest to South Boulder Creek (6.25 miles : 6,740’). It crosses over the creek on a wide bridge to its north bank and flattens considerably for several hundred yards. This enjoyable section offers easy access to many good fishing locations and viewing areas along the creek.

Just beyond Walker Ranch Loop’s Mile Marker 1 (6.5 miles : 6,740’) the trail turns sharply left and begins a strenuous, winding climb back to the South Boulder Creek Trailhead (7.55 miles : 7,287’). This barren and exposed area was stricken by fire in 2000. Informational signs describe the event and explain its ecosystem before and after the fire. Despite extensive damage, grasses and wildflowers have reclaimed these hillsides and recovery is well under way.
