The Best Views of Barcelona from the very popular Passeig de Les Aigües in Parc Collserola. Easily accessible on both ends by Metro stations on line L3: 'Zona Universitaria' on the West side and 'Penitents' on the East side. The middle of the trail is accessible by the FGC, Peu de Funicular station; get off of the funicular in the middle at 'Les Aigües'. The funicular is the best option for getting bikes up to the trail. Enjoy the spectacular views!
