1. Golden Gate Bridge
Golden gate bridge is the most popular landmark of San Francisco and it looks almost identical to the bridges in Istanbul. I always wondered which came first and why they look so similar. But in the meantime, I always wanted to visit this city just to see the bridge closely. So, let me tell you the story behind it.
In the 19th century, an explorer came to San Francisco and saw the San Francisco bay and coastal hills of San Francisco. The view suddenly reminded him another harbor: the Golden Horn from Istanbul (it was called Konstantiniyye at that time, even though western cultures keep calling it Constantinople). In his memoirs, being inspired from the Golden Horn, he described this Californian bay as Golden Gate in Greek. he even used the term "a golden gate to trade with the Orient" as he opened trade lines through Pacific. So in the 20th century when they built the bridge to connect two main parts of the bay, they called it Golden Gate Bridge. So the name was never about the gold, the color of the bridge or any other detail - it was always about Istanbul. So at that time, Istanbul didn't have any bridges on Bosphorus and in the second half of the century, they managed to build an identical bridge - except the color. I should highlight the fact that the bridge in Istanbul was not built on the Golden Horn tough - let's discuss it in another post.

The bridge is one of the longest suspension bridge and is painted with "international orange" color to make it highly visible by any ship passing from the Pacific. I cannot say if the color worked for sailors to recognize the bay or not, but it definitely made the bridge internationally famous and gorgeous!
There are many ways of getting the best view out of the bridge and the first one is to check out the visitor's center. It is super easy to reach with public transportation, there is a bus stop practically in front of the center and it is also easy to park if you come with your car. You can walk around and learn about the history of the bridge or just take photos.

The bridge also has sidewalks for the visitors. Even though there was a time that pedestrians and bikers were asked to pay a fee to cross, it is for free now. You can cross the bridge on foot in about 1 hour. We didn't cross the bridge completely but a little but of exploration gave us some opportunities to take amazing shots of the bridge.
If you are into hiking a little bit, you can walk up to the Marshall's Beach and it's definitely worth it! Make sure that the ground is not muggy and you have good shoes to climb up and down. Alternatively, there are Baker beach, China Beach, Marin Headlands and many more. They are still on my to-see list as well, I will write more later.

Even though it's not that close, if you start exploring the beaches around the Golden Gate in the search for the best shot, you might consider visiting Golden Gate Park as well to visit either Japanese Garden or California Academy of Sciences, which is amaziiing!
Inside, they have a sphere replicating the rain forest environment with perfect smelling plants and huge butterflies all around. Especially if you are traveling with children, you must go - they will love it.
2. Fisherman's Wharf and Pier
Some say Fisherman's Wharf is extremely touristy and that is why I was hesitating to go in the beginning. But then, I thought "heey, why not!?" Anyways, we decided to visit it on our first trip to San Francisco so these are my ideas about the topic: 1) it's completely touristy and 2) it was worth it.

The Fisherman's Wharf has many attractions during the day, street artists, sea food, activities, museums. Plus, it's on the seaside, so even if you are interested with any attraction, you will appreciate the sea smell and sunshine.
From the shore, you might follow the path to reach Pier 39, from where you can view Alcatraz, Golden Gate Bridge and Bay Bridge all together. Once here, take a walk around the Pier and spend some time observing the sea lion colony around. Pier 39 is also where Hard Rock Coffee San Francisco is located, so if you are into souvenir shopping, don't miss your chance.
