Carretera de les Aigües

Carretera de les Aigües traces a level line along the Collserola hills above Barcelona, making it a rare flat route in an otherwise hilly natural park and a favorite among runners and cyclists for its unbroken views over the city and the sea beyond. Unlike more rugged Collserola trails, its wide, even surface requires little technical effort, which explains its popularity for both serious training and easy sunset walks. Its strong local and aesthetic scores point to a route embraced more by residents building it into their routine than by first-time visitors.
