La Carretera de les Aigües

The Carretera de les Aigües is so named because of the water pipes that once ran along this path, and retains its horizontal layout. It is almost 10 kilometres long and, at its highest point, stands 450 metres above sea level. It is one of the locals' most popular cycling and walking trails. From Sant Pere Màrtir to the Carretera de la Rabassada, the viewing point on the side of Collserola that overlooks Barcelona is perfect. This simple, even path offers sweeping, matchless views of the city.
