From A3 , head north on B82 to Gladstone , then east on C843 and C845 ( 17km of unsealed road ) to arrive at the northern entrance of Mount William NP and its five campgrounds . In the south of the park is the 1889 Eddystone Lighthouse .
This entire stretch of coastline is set in sugar-white sandy beaches studded with granite boulders draped in orange lichen and lapped by azure waters . It is impossibly beautiful . The Bay of Fires includes a number of free , beachside campgrounds ; these are most easily accessed from Binalong Bay Road just north of St Helens ( C850 ) and then Gardens Road ( C858 ).
St Helens makes a good base if you prefer to settle in one of its caravan parks . Most supplies are available , and then , of course , there is more of that stunning scenery with a dune system in the St Helens Conservation Area . St Helens is also the northern end of The Great Eastern Drive .
The Tasman Highway continues south , hugging the coastline with some forest reserves to the west . Along the way , a few coastal towns offer caravan parks and free campgrounds , such as Lagoons Beach near Chain of Lagoons .
Bicheno is a great place to spend a few nights before heading to Freycinet National Park .
Mt William National Park .
