The amusement park is located on Tididabo Hill, but it is not open every day. I went to the official website in early October. It was only open on weekends. As long as the garden day, there is a tourist bus called t2a, which can sit directly on the top of the mountain from Catalonia Square. The amusement park is open every day from summer vacation to mid-September. At other times, you'd better check the official website before you leave.
