This is a classic introduction to the Danskin's backcountry and is going to be an adventure for the first timer. The trails are not marked so it will be vital to follow the route closely so you do not stray off course. There is a mandatory hike-a-bike and some very steep sections which will hurt if you fall off the trail. This route is only for very experienced and in shape riders!
To start the ride, you'll either want to park at the bottom of Deadman Creek or at the Willow Creek
Trailhead. You just need to decide if you want to ride the road section at the end or the beginning. Please stay to the side of the road since there are a number of blind corners and there have been accidents recently with folks going down the center of the road.
If you park at Deadman you'll have a long climb to start with, all on singletrack that will work its way up the drainage. There is only one junction on Deadman's Cow
near the beginning that you'll need to stay right for, otherwise the trail is very easy to follow up to the saddle. Once at the saddle there will be a steep descent into Cow Creek.
trail along Cow Creek is a classic creek singletrack with a number of crossings. At the bottom of Cow Creek you'll bear right and climb to a plateau overlooking Arrow Rock Reservoir and join A South Forked Willow
trail. Ride along this plateau for a while and then you'll wrap around and start to head up the South Fork of the Boise River. This next section can be steep and challenging and the trail runs along a steep edge of the reservoir for a long distance.
You'll then come to a large meadow at which point the trail becomes very faint and goes nearly straight up the hill. Shoulder your bike and do the hike-a-bike. At the end of the hike-a-bike you'll be back on the plateau and on a good trail again. Follow this trail along the reservoir and up into the Willow Creek
Drainage. Once in Willow Creek
you'll have some deep water crossings before arriving at the road.
