There’s something about barriers to entry, particularly in a physical sense. When there is something stopping you getting somewhere it makes getting there all the more special. For visitors to the Daintree National Park that barrier to entry is a wide, crocodile living Daintree river.
The only way to get past this impenetrable toothed barrier (assuming you don’t want to swim!) is to put your car on the venerable Daintree ferry. Some want a bridge built, others abhor the idea, but for the time being the only way in or out to this natural wonder is a leisurely trip across water.
