One of the most iconic buildings in San Francisco is Coit Tower. Most people know this as the fire hose building.
The hike to the tower is treacherous. I walked from the Embarcadero BART station to Coit tower. There are many, many hills that you will have to walk up to get to the hill that Coit Tower is on. However, once you make the hike up to Telegraph Hill, you will get amazing views of the city. You can see the Golden Gate Bridge, Alcatraz, and so much more!
Visitors can go to the top of Coit Tower to get a 360 view of the city. For residents of San Francisco, it's $6 to get to the top. For non-residents, it's $8. Visitors can purchase tickets at the gift shop on the lower level of the tower. If you happen to go inside, check out the murals on the walls, they are beautifully fascinating. I didn't go to the top of the tower as I was on a time constraint, but plan on going back to make it to the top.
About Coit Tower: Coit Tower was designed for Lillie Hitchcock Coit after she bequested people use her money for the purpose of adding to the beauty of the city that she always loved. Coit was a patron of the city's firefighters, but contrary to what everyone thinks, the tower was not intended to resemble a fire nozzle.
