Located in the true heart of a mountain, this was an amazing trip. The ride up there was great, you see a lot of water while you drive up and when you get up there its just beautiful castle located in the rocks. Its the only one I have seen so far that is just built into the rocks. There is a small enterence fee of about 11 euros. There was a small cafe close by as well. A lot of locals live around this area, and they will drive a little faster than you but dont let that intimidate you on the road. Must visit.
