It is very handy to buy tickets online. The line for tickets was a couple of hundred meters long when I arrived. With ticket bought through getyourguide.com, I just entered the park without waiting. The park itself is great and very colorful. You can spend hours enjoying in both nature and Gaudi's architecture.

We were afraid we wouldn't be able to visit during our stay in barcelona after they told us tickets had sold out, but, thanks to GetYourGuide we got to and had a great time! The scenery and architecture is amazing and we even got to go up on the overlook and hike on the grounds! The view of barcelona from the top is definitely worth it.

A lovely park with interesting Gaudi features. There is currently a one way system in place (I think as a Covid measure although I am unsure as they seemed to let some people go wherever they pleased!) and the hill up to it is very steep! We had a lovely morning wandering the gardens.
