The 10 mile Blacktail Wild Bill ORV trail system has three legs. One begins off of Blacktail Mt. Road on Road #917a and intersects with the other two trails which begin off of Truman Creek Rd #213 and from the trailhead on Road #2990. The trail is open for the following uses: 3 or 4 wheeled vehicles, 2 wheeled vehicles, mountain biking, horseback riding, and hiking.
There are three trailheads to access the Blacktail OHV system.
Start for Trail #917: From Hwy 93 near Lakeside, turn west onto Blacktail Rd (after turning, turn left immediately-- before the hardware store). Continue up Blacktail Rd which turns into Forest Service Rd #917 for about 12 miles. The trailhead is on the left.
Start for Trail #918: This trail can be accessed from the north off of Hwy 2 or from Lakeside. Please consult map for directions.
Start for Trail #919: From Hwy 2, turn onto Kila Rd for about 1.8 miles- going through Kila, turn left onto Smith Lake Rd (2/10mile), turn right onto Browns Meadow Rd (1 mile), turn left onto Truman Creek Rd (2.3 miles), turn right onto Wild Bill Rd after the pavement ends, continue up this road about 2.7 miles, and turn left down a seemingly private driveway for 1/10 of a mile, the trailhead is on the right. There is wooden three rail fencing on the left side of the drive. If you pass a road on the left (#9662) with an open field on the right, you’ve gone just a little too far.
