The iconic Twelve Apostles rock formations are one of the major attractions of the Great Ocean Road Australia. Located in Victoria, approximately 230 km from Melbourne, these impressive rock stacks are a must-see stop off for anyone embarking on a Great Ocean Road tour. The surrounding area also boasts a range of other natural phenomena, including London Bridge and The Grotto. Heres what to expect during a visit to the region:The Twelve ApostlesThe Twelve Apostles, located just east of Port Campbell along the Great Ocean Road, are the central feature of Port Campbell National Park. Created by erosion of the limestone cliffs, which began between ten and twenty million years ago, the Twelve Apostles sit isolated from the shore, rising out of the Southern Ocean up to 45 metres high. For particularly awe-inspiring views, visit at sunrise or sunset and watch the rocks change colour as they move from darkness into light and back again. Parks Victoria has set up plenty of boardwalks and viewing areas to ensure visitors get spectacular views of these majestic rock stacks at any time of day.

The Grotto

The Grottos clear, still pool offers an oasis of calm when compared to the lively, open waters of the Southern Ocean just outside. This geological wonder was created over thousands of years – a result of sinkholes in the cliffs being exposed after the rock was gradually worn away.

The Bay of Islands and the Bay of Martyrs

The limestone towers of the Bay of Islands are another impressive addition to the coastline and the Bay of Martyrs is a great place to view them. The rocks are particularly attractive at sunset when the islands and Massacre Point are lit from behind by the setting sun.

Scuba divers will particularly enjoy exploring the Bay of Martyrs and the adjoining Wild Dog Cave – one of the best places in the area for shore dives. Meanwhile, further along the coast is the famous Loch Ard shipwreck, which met tragedy on a voyage from Melbourne, bound for England. The vessels cargo can still be seen by visitors today, from lead ingots to a marble headstone.
