In case you did not receive an email for date and hours, send the one to
[email protected] and they’ll send you a detailed email. When you arrive at Pier 33, you just need to go to the information desk and show your ticket from the email, they’ll give you a receipt and with that you will stay in the line for taking on the ferry like all other passengers which are going to the Alcatraz. Alcatraz island is incredible! There are grass, flowers, birds everywhere, it’s good for taking a walk :)
Also, I took some walking tour at 3PM, Sarah was my park guide, she’s awesome, funny and chatty, she’ll introduce you history of the island itself.
The other thing is Alcatraz prison. For someone who’s into it, it will be great experience. Audio tour is awesome, I was really delighted and impressed.
As for the bike, I didn’t print a pdf from email, but I was able to rent a bike. A guy was very happy and in the mood. I suppose there are much better bike to be rent, but this was ok.
