For visiting the Alcatraz island, you need to book the slot beforehand. And I would suggest you to book it online as it's cheaper. We got it for around 40$.
So, Alcatraz island is an abandoned prison and it has an oldest operating lighthouse on the west coast of USA. It sounds boring right? But it's not. Infact, it is so interesting and spooky and it keeps your heart racing the whole time. We went on the night tour to feel the creepiness of the place .
This is a guided tour. You have to take a ferry and you will reach the island in 15-20minutes. After reaching, the officers will guide you through and you will be given a personal audio tour kit. It's very well organized and it keeps you engrossed throughout.
Apart from the prison, the island is a home to the seagulls (be careful of them) and the tripping beauty of the SF skyline, Golden gate bride and the Oakland Bay bridge.
It's a pretty time consuming tour(around 2-3 hours),so I would suggest you to plan it accordingly.
This was the last stop of the day.
