I took a river cruise with Bruce Belcher of Daintree River Cruise before the ferry across the Daintree River. Very good. Not all the passengers paid - we had two green tree frogs for company! If I had worried about not seeing any crocodiles I needn't have done. Learnt how to tell freshwater from saltwater crocodiles - the freshies have narrow snouts where the salties have broad ones.

The Daintree is an ancient rainforest still surviving despite the inroads of civilisation. There are pressures on it from the feral pigs whose diggings are foul graffiti on the forest floor. And residents who want all the comforts of a big city. The Daintree is also unusual for a rainforest which meets the sea (at beaches like Thornton Beach).

The Daintree Heritage Lodge was my first taste of ecotourism. The restaurant was amazing - at night getting there in the dark was an adventure. When you did get there it was more like tables had been set out among the trees. Candles provided token illumination and if you heard a rustling in the undergrowth you feared for the other diners.

In the morning you could see one edge of it overlooked a secret stream winding its way through a leafy gorge below. To supplement the restaurant fare I tried the green ants you can find on the trees. If you lick their posteriors it's like lemon flavoured battery acid. Has a happy zing to it! Homely off the beaten track stuff.

The Lodge is set in a rainforest which feels surprisingly empty, and dim as the canopy cuts down on the light reaching the ground. You hear sounds of the life in the canopy (including the noisome flying foxes.)

I didn't see any rare cassowaries as I hoped but I did go on two good walks with Cooper Creek Wilderness tours. One was at night and I learnt about eyeshine and shining a torch around to spot life by the reflections from their optic systems. Saw birds sleeping on the ends of branches so vibrations from snakes climbing up would rouse them. Met one of the unwanted cane toads which are killing off predators which don't expect toads to be poisonous. The calls of the cane toads pollute the night.
