It's about a 9 minute ride to go up. What surprised us is that once you get to the top there's not much there. There's an okayish viewpoint, pricey restaurant and 50 cent paid toilets but no castle. For the castle you need to hike about 20 minutes down over a steep path with sharp rocks and slippery walks. Not entirely safe for little kids. Walking the same way back up is quite a climb. The prices recently have gone up quite a bit. Adults are now 5,50 euro each for a return and kids 3,00 euro each for a return. Kids of 2 or younger are free and can come along. They however don't check for tickets when going down so you could just as well opt for a one way ticket. The walk down from the castle is well doable. Even more doable than the half hour walk back from the castle up to the chairlift. Having said all that, the ride itself is quite nice. My son of 3 loved it. There's free unlimited parking right next to the start of the chairlift so don't park at one of the paid three hour places throughout the village. If you don't care much for the chairlift but just want to visit the castle just drive up to the castle instead. You can park only 5 minutes walking away from the castle entrance.
