Looks like they’ve “improved” the site. It was some distance from anything else. I rode there with a friend once, took a taxi there the second time, and drove myself the third time I visited the Castle. It was a lonely and beautiful place. No parking lot, no flag pole, at the time.
this looks much as it did when I was last there:
