I was dissapointed after walking all the way up there and finding out that you had to buy a ticket to get into a park! I get it that you have to pay to get into Gaudi’s house and stuff but a park?! plus, there were no tickets left. I recommend you buying your tickets in advanved if you want to get in. however views from the city were great! You can walk around the park but not get into the actual park, where all the cool sculptures are without a ticket.
