Lombard St. in San
Francisco, California,
USA. It's a 1~way downhill steep street with many switchbacks, is lined by several homes, the speed limit is
5 MPH & it goes from Van Ness to Leavenworth. The views are outstanding!
You won't believe this but I accidentally drove down the crookedest street in the World & didn't find out it was that street until a month
later! I swore I'd
never drive it again but a week
later I did. The views are phenomenal.
