While there is good parking and a loo at the car park mentioned, the single track road up is actually public as far as the cattle grid (about half way) and there is a pull-in there for one car at least and another spot just before that. Not many passing places though. So, if you are lucky you can avoid the worst of a reasonably steep 1.25 mile walk uphill. Whatever, it is certainly worth the effort to view this important stone, the remains of the WWII anti-air craft battery and the great views.
