At high tide, rocky headlands block the route to Cowes, but by walking west, you can walk about 4 km before rocks make progress difficult and slow.
It's possible to walk all the way around the island, but this takes several days and the tide needs to be low.
Our coastline has a blend of wide sandy beaches, rocky headlands and rocky reefs. When exposed at low tide, these reefs contain rock pools, and all manner of shellfish, sea weeds and other marine life. Sadly, in the 12 years we've lived on Phillip Island and explored these rocky ledges, the diversity of life in and around the pools has diminished. Pollution within Western Port Bay has to be the culprit.
