The Mukhart River, whose name means no-through road, is a small river flowing on twenty kilometres (12,43 miles) along the Bor Khyar Dunes, forming a lovely oasis in which poplars and sea buckthorns grow. The source of this river is really magical because it literally gushes from the huge and lovely Bor Dune. As it spontaneously springs, it also spontaneously disappears afterwards in the dunes.
