Only the portion of West Grouse Creek Trail #2129 that is shown here is open to bikes.
There is a sign at the Grouse Creek TH that would make you think that bikes are not allowed on ANY portion of this trail, but the Minturn Ranger Station holds that this portion is open to bikes.
From the trailhead, follow the dirt road through pastureland for approximately 1/4 mile where the road turns left. The trail begins here and continues straight before reaching a fork where the Grouse Lake Trail goes left. Stay on the right trail, which quickly enters dense stands of conifers. At a junction with an old, decommissioned Forest Service road leading to Meadow Mountain, the trail effectively ends for bikes. This trail is best used as part of the Lower Grouse Creek
continue west of the Meadow Mountain cut-off.
