An amazing place to visit, I went only for the radar station. It was fenced but close enough to see details. No one there and no cameras when I went so you could walk around the facilities, no trespassing though over the fence to the radar station. The view from the peak is also spectacular, you can see California and far east and west into Oregon. Keno is covered by thick trees, but the view is still great. Would recommend to anyone interested In the cold war, us politics or Soviet / Russian politics; or if you are just on a drive. I will definitely come back to bike or hike around and enjoy the area once more.
