The Heads
As you look out to sea, you can view the only entrance point into Port Phillip Bay. The entrance, known as the "Heads" is 3.05 km apart, however, the reefs on either side restrict the navigable channel to about 300 metres. In the early 19 century many groundings and wrecks occurred as mariners attempted the passage through the "Heads". Today, the Sea Pilots help guide ships through this dangerous entrance to the bay.
