This path runs along a part of the foothills of Sant Pere Màrtir hill (easy to identify thanks to the repeater on the top). The path to Finestrelles is a small walkway which goes around the high part of the neighbourhood of la Mercè, from Av. Pearson to Sant Joan de Déu Hospital in Esplugues de Llobregat. It runs parallel to Passeig de les Aigües, at a lower attitude however, which makes it more accessible. Strolling along this path provides us with amazing views of the city, such as the peculiar Parc de Cervantes and a grasp of the growing city, which has swallowed up urban areas far removed from its centre, including the Monastery of Pedralbes. The sights are even more spectacular from the viewpoint situated opposite the huge water cistern, a rectangular concrete structure; it is visible from any point in the city, though its colour tends to blend in with the scenery. The city looks tiny from over there, where you can see as far as Badalona and Castelldefels as well as important landmarks such as El Prat airport, Camp Nou, Montjuïc Olympic Mountain and the modern area of Diagonal Mar.
