Following another night by the Fitzroy River, we head for Bunuba country - once a Devonian reef, this terrain is over 350 million years old and home to a diverse array of animals and plants. In the morning we seek the adventure of Tunnel Creek, a 750-metre cave system in which we discover secret caves and a large variety of wildlife. It is here we also learn the legend of Jandamarra, an Aboriginal freedom fighter who used the tunnel as a hide-out in the late 1800’s. Travel to the geological wonder of Windjana Gorge, a delightful oasis in the outback; beneath gorge walls rising 90m, we enjoy a picnic lunch and search for freshwater crocodiles, local birdlife and indigenous bushtucker. The Gibb River Road then leads us from the picturesque Napier Ranges as we begin the return to Broome via the Derby ‘Boab Prison Tree’.
