Beneath the peaceful countryside of Buchan lies a labyrinth of more than 1000 limestone caves. These caves formed around 400 million years ago when rivers and rainwater cut through the rock to dissolve the limestone. The result is calcite-rimmed pools, stalactites hanging from the roof and stalagmites growing from the floor. Just a handful of caves are open for the everyday adventurer to explore, including Royal Cave and Fairy Cave where tours run daily. They are well lit, sit at a naturally occurring 17 degrees and are considered some of the best in the world. There are short and long walks in the surrounding bushland, too, where you might encounter kangaroos, emus, echidnas and more than 60 species of birds.
