Alcatraz Island.

The Rock! The worlds most famous prison. This is a really interesting place to see and they offer an audio tour upon arrival on the island so you know what you are looking at whilst you are there at no extra charge. The ferry to the island was around $US24 each and you want to line up early for tickets if you don't book online because the line can get pretty huge.

Coit Tower SanFran

This is an amazing viewing platform and is well worth the $US5 entry fee. You can see the entire city with a full 360 degree view!

Seeing SanFran By Bike.

This was a really good way to see the entire city, and cheap. There was just one problem..... The seat absolutely kills your ass!!! I am not joking, I was sore for days having to sit on alternate cheeks to avoid the pain! The entire city is undulated and it seems as if you are constantly riding uphill. That aside it was good to be able to say we rode across the Golden Gate Bridge.
