There are numerous ways to enjoy Barcelona’s outdoors, but this mountain that looms over the city may be one of the best. Adventurous travellers can make the hike up to the summit through the Serra de Collserola natural park (approximately 2–2.5 hours), but if you just want to enjoy the attractions at the top, you can catch the Cuca de Llum funicular. Once at the top, you can revel in the views, explore the majestic Temple of the Sacred Heart of Jesus or experience an adrenaline rush at the Tibidabo Amusement Park.
