As one of the largest single-span suspension bridges in the world, the Golden Gate Bridge is a must-see to San Francisco, not only for tourists, but also for local people. Looking over the Golden Gate Bridge is absolutely a kind of enjoyment. Specially made orange (said to be called International orange, can be found online formula of color) is connected with the blue sea and sky, and any picture is the effect of postcards. Personally, I strongly recommend walking or cycling across the Golden Gate Bridge when weather, time and physical strength permit. This is one of the many strategies that everyone must do in their lifetime travel. The bridge is 2.7 kilometers long and can be completed in about an hour and a half. On the bridge, you can not only feel the shock of the bridge, but also have a long view of the famous Devil Island and San Francisco city scenery.
