Serene Skunk Canyon in Boulder Colorado

Crude map of the route. Note that rerouting of Skunk Canyon is not depicted. 

Very few people do the Skunk Canyon/Kohler Mesa Loop in Boulder because the trails are hidden behind the NOAA complex on Broadway. The government buildings, gate, and Federal police look intimidating,  but the public is allowed to walk across the campus, they are just not allowed to park there. Fortunately, there is an RTD Park and Ride right across the street at the corner of Broadway and 27th Way (entrance is on 27th Way). Park there, cross the street, and walk around the right side of the white NIST building (a cemetery will be on your right and NIST to your left). At the end of the cemetery is a bike path adjacent to the campus child care center. Follow this until it dead ends at a gravel road heading up towards Kohler Mesa (at 0.5 miles). Before the first switchback in the road (at 1 mile), the Skunk Canyon Trail starts on the left at a cleft in the fence.

Starting out across the NOAA campus. The NIST building is just out of frame to the left. Keep following the road.  

Just past the cemetery (out of frame to the right), is a path that heads west, take this and pass the child care center. 

Kohler Mesa is the hill straight ahead. This path will dead end at the gravel road. 

The Skunk Canyon Trail has been rerouted since the Sept 2013 floods and now switchbacks up the side of Kohler Mesa before heading deep into the canyon. In spring this area is a verdant oasis of green grasses dotted with grazing Mule Deer, wildflowers, and Chickadees flitting from pine to pine. Because of its isolation, there are few people on the trail, a rare treat in crowded Boulder.

Starting up the gravel road, which was completely redone in 2013 after the floods  nearly washed it away. 

The start of the Skunk Canyon Trail. Ignore the social trails in the valley to the left. 

With every step up Skunk Canyon, the views of the Flatirons grow closer and civilization drifts away. 

At 1.6 miles and 440 ft elevation gain, is a junction with a spur trail that ascends quickly to the top of Kohler Mesa. Take this for a shorter loop. At the far end of Skunk Canyon, the vegetation becomes more dense, encroaching on the path. It is another 300 ft and 0.7 miles to the intersection with the Mesa Trail. From this lofty perch, south Boulder becomes a hazy post card of streets, trees, and raptors drifting on the wind.

The canyon walls narrow.

On the Mesa Trail

At this point, it is only another 0.4 miles to the start of the well-marked Kohler Mesa Trail. Stop a moment at the junction and look to the left. An old cabin is visible in the trees. A trail passes this cabin and ascends roughly to an old quarry where locals have made lounge chairs out of rocks.

Kohler Mesa was damaged in the 2013 floods, and the trail is rocky, rutted, and tedious to traverse. Still, the hiker is rewarded with a secluded glen of Ponderosa Pine and resident herd of Mule Deer. At 3.14 miles, the trail comes to a fork. Take the right fork to follow this route or the left fork to descend via social trails. At 3.44 miles, civilization returns as the trail ends and the route follows the gravel road back down to the Federal campus.

Mule Deer graze all over Kohler Mesa.

Back on the gravel road. Views of Boulder abound. There are a couple of picnic tables under the tree just ahead. 

For those looking for something different to do and who don't mind a little civilization intruding on their day, the Skunk Canyon/Kohler Mesa loop will be just the thing! You can also get to Kohler Mesa via NCAR and the Mesa Trail (view post).

Cenntenial Cone: Mayhem Gulch and and Juniper Trail Loop

Distance: 5 miles round trip
Elevation: 6,620 ft - 7,542 ft
Elevation Gain: 922 ft (cumulative)
Bathroom at Trailhead: Yes
Dogs: On leash, Jefferson County Open Space

Rolling hills and Ponderosa Pine are the primary views from Centennial Cone Open Space

Centennial Cone Open Space near Golden Colorado is one of the newest open space parks in Jefferson County. Its 3,000 plus acres surrounds a 8,679 ft hill called...you guessed it...Centennial Cone. While there is a very long twelve-mile loop that circumnavigates this monolith, there is no trail up it, which will frustrate any peak bagger looking with anticipation at the topo map. There are a couple of shorter routes from the Mayhem entrance (covered in this post), and the Camio Perdidio entrance off of Golden Gate Canyon Rd. This makes Cenntennial Cone more popular with mountain bikers than hikers, the former getting to ride without interference on alternating days (see the PDF calendar on the official web page).

Trailhead

Trail map showing the Mayhem Gulch-Juniper Trail Loop

The Mayhem Gulch entrance is located 9.5 miles up Clear Creek Rd/Hwy 6 out of Golden, CO. This route follows the twisted path of Clear Creek, which survived the 2013 floods much better than its northern neighbors. There is a large parking lot on the right hand side with an obvious trailhead.

Looking down on the trailhead and Clear Creek

The Mayhem Gulch Trail begins climbing right away in a series of long drawn out switchbacks that weave in and out of the crenelations in the hillside. South facing, this hillside is covered in Sagebrush, Utah Juniper, and Ponderosa Pine. Blessedly, it can feel warm even on a less than ideal day.

At the junction of the Mayhem Gulch Trail and the Juniper Trail (1.7 miles, 518 ft elevation gain) we chose to go left. At 2.5 miles we arrived at the junction of the Juniper and Travois Trails. It is just a short jaunt to get back to the Mayhem Gulch Trail.

Sagebrush and blue skies. A typical Front Range tableau in early Autumn.

Cenntential Cone is typical Front Range Open Space. It is great for shoulder season hiking or a sun fix on a cool day. If you monitor the mountain bike calendar, then you can be assured of hiking free of the two wheelers. For a longer hike, take a side trip up the Travois Trail, which in one mile leads to some interesting rock formations.
