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.
