A bit north of Port Douglas, you can happen onto the small town of Daintree, which sits on the river of the same name. Here there are several operators offering short river cruises to see what lurks around the bend. Most of the lurking is the province of the estuarine crocodile, some of which can buff up to 7 meters in length. Our grizzled guide took extra pains to be sure that we saw four of them, at a range the squeamish would call “close”. Other animal life in the area seemed limited to birds, since the gators can’t catch them, and include the Kookabura and the showy Azure Kingfisher. We noticed, and our guide lamented, that the area around the river is becoming developed for agriculture.
