1. If you are someone who is interested in Alcatraz or historical prisons in general, then the Tour of Alcatraz is a must-see! We went in the afternoon coz there were no more night tours available but people have highly recommended the night tour because it is an enhanced experience of what life was like in the prison and on the island.
2. The prison is still very well maintained and the audio tour was fashioned in such a way that would allow you to appreciate the events that took place while appreciating the beauty of the island. It takes more than two hours to finish the tour but there was never a dull moment.
3. San Francisco is chilly year-round so if you decide to do the tour, be sure to bundle up for the boat ride and wear layers for when you set foot on the island. It is not as cold inside the prison, but it is outside especially when you get to the ridge overlooking San Francisco.
4. Last but most importantly, bring a camera! You may not want to savor the moments inside the prison but the views from the island and on the boat ride are breathtaking.
