Which cable car line goes down the hilly street? (Lombard?)
The street you’re probably thinking of is Lombard Street, famous for its steep, crooked section with tight switchbacks lined with flowers. However, no cable car line actually goes down Lombard Street itself. The iconic cable car lines in San Francisco run along different streets, primarily serving steep hills, but not the winding portion of Lombard.
The main cable car lines in the city are:
If your goal is to experience Lombard Street, the best approach is to walk or drive down the street itself. Many visitors park or take a short walk from nearby cable car stops on Hyde Street (near the top of Lombard) to view and photograph the famous curves.
In summary, you can use the Powell-Hyde line to get close to Lombard Street and enjoy the surrounding hilly views, but no cable car travels directly down Lombard’s twisty section.
