We cruise past Calabash Bay where there are a few famous Aussies living in seclusion.
This will be followed by a National park area where there is nothing but nature.
Last bit of civilisation is at Collingridge Point, named after George Collingridge who was one of the first Europeans to have settled here with his wife Lucy.
Visit to Aboriginal site(s) to inspect rock carvings and possibly middens. The Dharug tribe moved into the Hawkesbury area about 50,000 years ago but the population numbers didn’t really develop much until about 4,000 years ago.
There are thousands of aboriginal middens all along the river – old piles of oyster shells and ash from fires.
