The Dubuji Boardwalk at Myall Beach,Daintree wilderness is very interesting and will educate you about the mangroves and the forest.
It is an easy walk that takes approx 1 hour.
Don't forget to take insect repellant and drinking water,some visitors have been badly bitten because they did not take heed regarding this valuable advice.
Most Travellers are told to do a nightwalk in Cape Trib, but what most people dont know is that Cape Trib has been farmed & logged over the last 100 years, there are quite a large number of domestic dogs in the area too. If you want to see the true daintree you need to do a nightwalk with coopers creek wilderness. Pru, Neil & Angie are awesom, very eco friendly and know their land well, you have a higher probability of seeing wildlife there than in Cape Trib itself. This photo of a Cassowary was taken by a friend of mine that I took into Cooper Creek.
