Tibidabo is a hill overlooking Barcelona, Catalonia, Spain. At 512 metres, it is the tallest hill in the Serra de Collserola. Rising sharply to the north-west, it has views over the city and the surrounding coastline. The summit of the hill is occupied by the Sagrat Cor church and adjacent Tibidabo Amusement Park. The Torre de Collserola telecommunications tower is a short walk away. All three are prominently visible from most of the city of Barcelona.
