it is 4€ to get up to the castle in the funicular and another 11€ to get into the castle and walk around. i did not take the funicular - I walked. its a pleasant walk under the trees. I also did not go into the castle but I walked around it. it is quite large. a great experience would be to take food and juice and have a nice picnic at the top as the view is beautiful. One piece of advice - dont walk down the if it is raining. the water rushes down like a flodding river! my shoes were soaked by the time i got to the bottom.
