Take the trail leaving the parking lot heading northeast (right of center as you enter the lot), follow the trail straight and then right, down a steep descent into the canyon. At the junction with the sign post, choose the Lower River Trail or North Bank trail, depending on the wall you want.
For The Dude and Unleashed Walls, go straight to Lower River Trail . After bearing left, look for bolted walls on your left.
For all other walls, go right across the stream to North Bank trail. Follow the trail and take the appropriate right-hand trail, uphill to your desired wall.
