Lombard StreetMost visitors drive down Lombard Street - it's one-way and you can't drive up. Others walk to the bottom, watch for a minute, take photos and leave. You can also get off the cable car at the top and walk down.
Pros and ConsLombard is a San Francisco oddity and lots of people enjoy seeing it, gathering bragging rights they can exercise with the folks back home. The wait to drive one curving block can be long - and the drive is finished in less than a minute.
