I took the cable car a couple times from powell down to the wharf. Everyone should do this at least one time. Prices for when I visited was $6 one way or $13 for all day pass. I was a little confused for people who just hopped on at stops along the way and didnt show a receipt or pay any fare? But they made sure to collect our money when we got on at the main turn about stops.
NOTE-if you are in a hurry to get from Wharf to Powell St-beware-time can vary! On two different days they were having problems with the cable system and there were significant time delays where we sat in the street for 30 mins plus till I decided to get off and walk back toward union square.
