Located at the western side of seashore in San Francisco is the Cyprus Tree Tunnel, an unnoticed gem of a view. There isn't much signs which will lead you here, you will find this while driving by as it gets crowded in daytime.
I reached there early in the morning and couldn't find anyone as it was raining and i got to enjoy the view in detail.
Recommend going there early in the morning to avoid the crowd and get nice photos.
