Tickets range from buying online or there. You can find them online for $35-$40 a person, there is higher.
$37.50 on-line that includes round-trip Ferry
I would recommend to go to the pier even if online tickets show not available as you might get tickets there. Last week it was showing full online and tickets on the counter were available easily. Ticket price 37.25.
Its around $37 a person and once youre on the island you can take as long as you want
$37.25 for adults online at Alcatraz Cruises
We recently paid $37+ online. Always buy tickets in advance since they are always sold out.
