You can get tickets right now,the start of winter season pretty easy during the week but always try to book ahead of time if you can at least a week.
https://www.alcatrazcruises.com/tour-options/ There's a few options, ranging from $38.35 to $90.50, depending on how much you want to go to areas not accessible to the general public. However, as with other national parks, your best experience on Alcatraz depends not on where you go, but on seeking out the rangers to share the lesser known stories of the place with you.
For an adult, 18 to 61 years of age the price is $38.35
