San Francisco is a popular tourist destination. The main tourist attraction is the Golden Gate Bridge, but it is also well known for its cable cars, Coit Tower, Alcatraz Island and Chinatown. It has a mix of Victorian and modern architecture which makes it an interesting place to walk around. There are steep rolling hills which are lovely to look at as well. There are beaches which are great for walking and hang gliding but not suitable for swimming or any water sports due to the dangerous tides. The population is very diverse, meaning that there is a great range of shops catering for all tastes.
