Gunsight Pass Road, Forest Road 585, branches from Slate River Road approximately four miles west of Highway 135. It is the second fork in the Slate River Road and well marked. The turnoff leads steeply down to the Slate River, where you'll see a dilapidated wooden bridge. Don't cross the bridge, it will not support a vehicle. Instead cross the river to the left of the bridge, where the water is relatively shallow. (It's a good idea to check the water level before crossing as it changes from year to year and season to season.)
Look for the dirt road on the southern shore of the river and follow it as it turns to the right. Shortly after the road bears to the right you'll come upon a gait. Please close it behind you. The road passes by some mining ruins then begins to quickly switchback up the mountain. There are two sets of switchbacks before the road reaches the Daisy Mine. From the river crossing to the Daisy Mine ruins is five miles. There are good places to turn around shortly after passing the Daisy Mine, which will be on the left side of the road. The road above the Daisy Mine is not recommended for four-wheel drive use. Other drivers may be encountered on this route.
