Even during the most crowded summertime days, here you can breathe tranquillity, especially early in the morning.
Want a spectacular 360 degree view of San Francisco? Head for the top of Twin Peaks; these two hills rise almost 1000 feet above the City and are located just about in the geographical center of the City: from there you can see many of San Francisco's landmarks. That's truly one of the most spectacular of all the San Francisco sights! Twin Peaks is where locals seek to impress their guests. If you come up here on a clear night, the lights of the "City by the Bay" sparkle below you in every direction.
Also known as the “Seven Sisters” this pretty iconic spot is a row of Victorian style houses from the 1890’s climbing one of San Francisco’s many hills. Visitors come from far and wide to photograph these beautiful structures. Located just across the street from Alamo Square, that's a nice neighborhood to spend an afternoon. Bring a picnic lunch, some board games, even you dog can come to take full advantage of what Alamo Square has to offer.
Lombard Street is quite an uncommon avenue; due to its famous hairpin turns, it's probably one of the most photographed streets in the world. Along with the Golden Gate Bridge and the Cable Car, that's one of the SF's must see.
The Golden Gate Bridge first opened in 1937. It also went by the name of "the bridge that couldn't be built" due to its incredible size. This fantastic bridge connects San Francisco to California's northern counties.
