Depends on what tour you get (day vs night). Night is more expensive. I was able to get day tickets for about $39 per person. There's also companies that package the Alcatraz tour with tours of San Francisco. So it all depends on what you're looking to do. I bought my tickets from: https://www.alcatrazcruises.com/

The Tour costs 40 dolars
I paid $38.35
