Most probably, one of the most famous bridges in the world. The GoldenGate Bridge is such a marvellous piece of engineering! Every bolt, cable and beam has been so carefully designed and the ongoing maintenance ensures that it never gets old. Be aware though, unless it is very warm, don't be fooled by the pleasant breeze of air when you walk towards the bridge, a proper wind stopping jacket is a must.
Take a few minutes, to stop and watch.
