At Wattamolla cove, the beautiful seaside place in the Royal National Park that we had to ourselves.  Royal is the oldest among the hundreds of Australia's national parks, and the closest to the country's largest city of Sydney (population four million), yet ironically hardly anyone was there, with all of heavy "crushed traffic driving right past it down the southern coast," enroute to Canberra and other populated places.  I guess the Blue Mountains and Kakadu are the country's most visited national parks, but we really loved it here at Royal.
