The castle is not that big, however, it is worth a visit as long as you find yourself in ljubljana. The ticket entrance is 10 euros, which l think it is reasonable, and it includes the museums, the tower and some other parts as walls and chapels. While the view from the castle is great, but l think the city does not offer that much as the style and the architecture seem like the same. Well, to conclude, it is not very impresive, just worth a visit. What l like best was the puppet museum.
