Tibidabo is a mountain overlooking Barcelona, Catalonia, Spain. At 512 metres, it is the tallest mountain in the Serra de Collserola. Rising sharply to the north-west, it affords spectacular views over the city and the surrounding coastline. The summit of the mountain 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.
