You can drive all the way, but the last 3-4 miles have areas of deep ruts, high stones, and several deep ditches. It would not be a good road without high clearance. Gorgeous views and solitude. The relocated lookout from here is off Twisp River Road, but it is on private property. We visited it - just be respectful. See Eric Willhite's website as he has a list of relocated lookouts.
