Came here on a Thursday at 9, which is when it opens because we wanted to avoid the crowds, and it worked - except for one school trip but we only ran into them once at the beginning. Tickets are sold down at the hill (the castle is on top of the hill so it is a bit of a trek) but there are not really any signs as to where to purchase the tickets. We only knew because shortly after we started up the hill, a kind soul told us that we need to purchase the tickets in the little house first because if you get up there and you don't have a ticket, they'll send you right back down. For the tickets, you have to pay cash and they want you to pay in exact change. We didn't have exact change (I mean who does, nowadays?) so we had to pay with a bigger bill and we realized that she shorted us our change. And she knew exactly what she was doing because as soon as we went back to the window, she immediately gave us the correct amount. You also can't bring water and they make you spill it out once you get to the top.

Other than that, the castle is very beautiful and there are lots of details. You can look at each room behind ropes and each room has an information plaque telling you what the room was used for. Overall, it took us about an hour to walk through everthing, once we were up there.

It also looked like they were setting up for some kind of event here. A wedding here would be beautiful (though probably very expensive).

Definitely worth a visit. Just remember to go early, buy tickets, and count your change!
