The Quoin Head track is hilly and steep in spots and does cross the Hammersley River. There are no special vehicle requirements and just before you actually get to the beach at Quion Head there is a very steep descent. There is a rough track that connects from Quoin Head to Whalebone Beach. This track has a nasty creek bed (FTZ09) that will require a degree of ground clearance and possibly low range, not reccomended for low vehicles. The track runs along small ridges and will take you over a small creek (FTZ11) and bring you to the beach at FTZ12.
Along the Quoin Head track you will see the Whalebone Beach track junction (FTZ27). This is an easy track to drive and will take you to Whalebone Beach and the western side of the Hammersley Inlet mouth. There is a descent to the beach(FTZ17) here and it is steep and soft(can be closed at times).
You will find camping at the end of Hammersley Inlet road. Along the Hammersley Inlet rd you will see access to the beach at FTZ71. This track will take you through the Hammersley sand dunes to the beach. It is easier if you let your tyres down as it can be soft in spots. There are a series of posts that will define a path for you to follow.
There is also camping at the 4 mile camping area. This is near Barron 's Beach and the eastern entrance (Hopetown end) of the park. There is also camping at Quion Head. There are clearings along the northern end of Moirs Track that allow camping along the Philip River.
