Locals visit Collserola Natural Park for its green space, but visitors flock here for views from the highest point in the Serra de Collserolas—1,680-foot-high Mount Tibidabo. Aside from its sweeping vistas, the mountain’s main draws are an amusement park and the Temple Expiatori del Sagrat Cor, an immaculate Roman-Gothic church that overlooks the city. The park also boasts an observation tower with panoramic views, a small house museum, and 14-century castle ruins.
Climb Mount Tibidabo on a walking tour, or zip up the hill faster on a guided, self-driven, electric car tour. You can also opt to enjoy the outdoors on a sunrise hike, or head out in the afternoon to explore and enjoy a gourmet picnic of Spanish and Catalan delicacies.
