Jasper Trail & Grapevine Canyon Trail Professional Guide
Detailed Trail Description from our Guidebook
"This route, used by four-wheel-drive enthusiasts, motorcyclists, mountain bikers, and equestrians, is also a worthwhile one for hikers—who, due to the length and elevation change involved, will likely want to travel one-way and downhill as described here. Off-days (weekdays, for example) are much better for avoiding motorized vehicles. Since the route is largely downhill, and almost entirely on soft sand or soft dirt, you can jog on it, too, if you want to make a faster descent. A section of the old California Riding & Hiking Trail sometimes coincides with and sometimes parallels the route. The description here assumes that you stay mostly on the easier-to-follow roadways."
