This beautiful castle is set high up on a small island - you can walk to it as there is a walkway which leads to it. It is privately owned, but you can visit parts of it. Tickets cost Euro 13 each which includes an elevator ride to the top of the castle. There is artwork to see and wonderful views of the island and harbour. There are no refreshments sold on the hill, so take water with you as it does get hot in July. Well worth a visit.
