Biking Trails

Boy Scout Trail

Boy Scout Trail

Description: In comparison to the adjacent mellow grades of Forest Hollow Trail, Boy Scout Trail (also known as “Scout Trail”) is a rip-roaring downhill that will make the most use of your brakes. While some hardy folks do ride/push up from town, it’s best enjoyed as the final (downhill) segment of a Forest Hollow and Scout Loop.

From the top of the trail, it begins to descend in a fast, steep and fairly technical manner. Many switchbacks and some sandy sections make for some hairy but fun moments. Exposure is common on this section so be careful. Also, watch your speed as hikers are abundant on this trail, often just around a blind corner.

Forest Hollow Trail

Forrest Hollow Trail

Description: After the long climb up Red Canyon Road and Lookout Mountain Road, you are rewarded with some of the best singletrack riding anywhere. Beginning high on the south rim of Glenwood Canyon, the trail meanders through thick pine forest and numerous fields of wildflowers and lush greenery.

Never does the trail depart from smooth tacky and narrow singletrack.

Grandstaff Trail

Grandstaff Trail

Description: Grandstaff Trail is a worthy destination for everyone who appreciates big views, flowing dirt and rocky tread, bermed turns, optional air time, and yes, a bit of effort to reap a big reward. Climbing Red Mountain Jeanne Golay Trail is quickly becoming the preferred way to enjoy a descent on this trail.

Two historic upper trail segments have been improved with better turns, drainage, and plenty of optional rock jump features to roll or pop over. The remainder of the trail is professionally built, featuring a wide enough bench to allow for easy passing, and countless berms along with a handful of tight switchbacks. Grade reversals along the trail offer expert riders plenty of air time opportunities, and some of the berms even have optional high entry lines to help you keep your speed out of the turns.

Most of the trail is in thick oak brush terrain, with occasional massive views of downtown Glenwood Springs, the Roaring Fork and Colorado Rivers, the Flattops and even Mount Sopris in the distance. Evidence of the Red Mt. Ski Area that graced the lower slopes of the mountain from 1938 to 1966 is seen with the few chairlift towers that remain. The trail goes under one of these bright orange steel tower structures, which makes for a great photo op along your ride.

Red Mountain Trail

Red Mountain Jeanne Golay Trail

Description: This dirt road gets you efficiently, but never too steeply, up above Glenwood Springs to a great viewpoint right next to “The Cross” which can be seen lit up at night time. This is a private land access dirt road, gated to motor vehicles at the trailhead, but open to public foot and bike traffic. The paved lower portion turns to dirt just beyond the City of Glenwood Springs‘ water system facilities. The road is known as the Red Mountain Jeanne Golay Trail, named in honor of the Olympic road race bicycle champion given her training and racing efforts on this dirt road.

Along the way up the road, you’ll note numerous singletrack trail segments that meet up with the road. Most riders use this road to access the Grandstaff Trail, either from the top, or at the several ‘kissing’ points along the roughly adjacent routes. The steeper segments that kiss this road are known as the Cross Trail. While open to bikes, the Cross Trail is a favorite for hikers and runners looking for a steeper workout. The lowest segments of the Cross Trail are steep fall-line trails with some deep ruts and occasional double diamond style difficulty.

The bright orange colored lift towers from the old Red Mountain Ski Area (1938-1966) can still be seen along the road.

The Rio Grande Trail is a rails to trails project which is built on the Aspen Branch of the historic Denver and Rio Grande Western Railroad.
