“Grand views, fun flow, big vertical, and optional air time, all just minutes away from downtown Glenwood Springs!”— Mike Pritchard
While the trail is mostly open to two-way bike and foot traffic (except for "Lower" Grandstaff), and the open view corridors at most of the turns are meant to minimize conflict between uphill and downhill trail users, many local riders enjoy riding up Red Mountain Jeanne Golay Trail given its consistent grade and plenty of shady spots. Start from the Olsen Trail to add some fun flat mileage and avoid the small crowded trailhead parking.
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.
In addition to the Red Mountain Jeanne Golay Trail (road), you'll find another older singletrack route on the mountain. Now called the Cross Trail, this fall line trail intersects Grandstaff with four-way intersections five or six times. Use caution at these intersections as the Cross Trail is popular with hikers and runners looking for a steeper and rockier experiences. While the Cross Trail is open to bikes, most riders will keep to the flow, speed and fun turns of Grandstaff.
Any ride is not complete without a stop at the highpoint and panoramic views a couple hundred yards east of the top of the trail. Nearby, a tall steel cross hints at the long and interesting life of William Grandstaff, who prospected for gold in the area and passed away on the mountain in 1901.
