It is difficult to buy Alcatraz tickets the day you’re planning to go so I advise searching the internet for tickets. I searched the internet and found Bay City Guide to have the best package pricing. I purchased the Alcatraz Night Tour (the 5:50pm night trip) and it was really interesting . It would have been better if the return boat was about 30-40 mins sooner.
It is an audio guided tour with 2-3 special presentations. I thought 2.5 hours is a bit too long to spend on the island because it was very cold. I would definitely recommend this tour and bring a warm coat.
The Hop on Big bus tour was great as well. I got to see the city in a short amount of time. My bus driver was Daniel and my guide was a funny Scottish man, Dough. He was hilarious and informative at the same time. He made friendly jokes about the passengers and everyone was laughing and enjoying themselves.
