The Great Ocean Road is a scenic coastal road along the southwestern coast of Victoria, Australia. It stretches for approximately 300 kilometers and was constructed by soldiers between 1919 and 1932. Major attractions along the route include The Twelve Apostles rock formations, although five of the original apostles have now collapsed, as well as London Bridge, which is not the famous bridge in London. Activities in the area include hot air ballooning, subject to the suitable weather and climate conditions.
