The Gap Creek waterfall, within the Watagans National Park, is arguably the best waterfall in the Hunter region. The Gap Creek waterfall used to be known as Brownie Falls, named after a pioneer saw-milling family in the Martinsville valley. The falls consists of a large amphitheatre of rock surrounded by rainforest. It is possible to walk across the drainage from the falls and then along an unfenced ledge to get behind the falling water of the waterfall. The waterfall is most spectacular after heavy rains, however it is wise to let the roads dry out before using them. A great spot to sit and relax at any time of the year.
