Visit today and you’re unlikely to spot rolling watermelons. The street – which runs east to west on the northern side of San Francisco – is great for pedestrians, turning into a series of car-free pavements and walkways as it approaches the bay. These include the Filbert Street Steps, which run through the Grace Marchant Garden and descend through a scenic stretch too steep for roads.

Glance up and you might spot some of the street’s other residents – a flock of wild parrots.
