Besides the famous Twelve Apostles, the whole Great Ocean Road has impressive cliffs, rocky formations sculpted over the sea of great beauty. One of the most striking is called London Bridge. Originally it was a ledge over the sea with two arches, which seemed like a bridge built on purpose. A whimsy of nature. The fact is that in 1980 the central section of the "bridge" broke down, disconnecting it from the coast ... and trapping two hikers in its central part. It took several hours by helicopter to rescue them. Imagine how distressing it must have been waiting hours.
