My wife and I finally visited this hidden gem on 17 Feb. Thanks to PJWoods for the directions. We parked near the hole in the bushes and tramped to the falls along a slightly muddy track. No sign of litter or any other people. The water was very hot but bearable, but the muddy sand on the bottom was much too hot. Even though I was wearing jandals the mud would squidged over and burned my feet. Thus I stayed close to the edge as things got hotter as I tried to get to the fall.
Great fun and lovely to have the place to ourselves. So peaceful. Long may it remain “secret”.
