Different tourists connect Tibidabo mountain/hill with different attraction located on it. Some people decide to visit Tibidabo, so they can see the amazing Sagrat Cor church (really spectacular!). Other tourists go to Tibidabo in order to visit the Tibidabo Amusement Park. You might wonder which of them is more worth it…well I recommend you to save enough time so you can visit both attractions. I cannot really separate one of them from the other because both of them are a ”must see” attraction. Do not hesitate to go 500 meters above sea level and visit Tibidabo, the overlooking views towards Barcelona are also pretty amazing.
