Wilson Creek is located on the north side of the Owyhee Mountains. The BLM maintains the Wilson Creek Road and Trail System primarily for recreational use, including both motorized and non motorized designtared trails. Also see the BLM’s Travel Management page for this area.
Wilson Creek Road. The road is easily reached from Nampa, Idaho. From Nampa take ID-45 south. Just after crossing the Snake River, turn right onto ID-78 and follow it west to for 3.0 miles to the well signed Wilson Creek Road. Turn left onto the road. The road is paved to a large feedlot and then turns to gravel and finally to graded dirt as it climbs steeply to a pass at the top of the drainage in 11.0 miles. The turn for the 4WD road that climbs up to Wilson Peak Road is is reached after 10.2 miles. I have observed a 2WD sedan drive to the pass but I would recommend you take, at a minimum, a high clearance vehicle and if you have a 4WD take it as the road can be difficult if wet and it is alway bumpy after after it turns to dirt..
After crossing a pass the road continues down into the Reynolds Creek drainage. When dry it is passable for high clearance vehicles.
On many spring weekends the drainage will be busy with horse trailers filling the lower trailhead parking lots, ATVers and mountain bikers parked in other spots.
Wilson Peak Road. This road leaves the Wilson Creek Road 10.2 miles from ID-78. It is a rough, ungraded road that leads to the summit of Wilson Peak in roughly 2.5 miles. It can be driven with a 4WD with good off road tires but it makes a better trail for hikers and mountain bikers. There is a spring and trough just off the main road that is a good parking spot.
