This lake sits high in K’gari’s inland dunes and feels almost too perfect to be natural. Known as Boorangoora by the Butchulla people, its crystal-clear waters and pure white silica sand are like nature’s own infinity pool. Since it’s filled only by rainwater, the lake is incredibly pure, in fact so pure that not much can survive in it. Most day tours stop here for swimming, photos, and just soaking in the surreal calm at the heart of the island.
