The most beautiful time to see the Nam Cuong sand dune is at dawn when sunshine spreads over the sandy grassland bringing out the “color resolution” contrasting light and dark, then gradually turning into a light orange color. (Photo: baogialai.com.vn)

One of the special features of the Nam Cuong dune is the change in its appearance every day and every hour. (Photo: baogialai.com.vn)

Just a gust of wind can change its visage. After one night, the footprints of humans and animals on the sand are completely erased, returning natural smoothness to the dune. (Photo: Tran Ngoc Anh)

The sand here looks like smooth silk pieces, sheep meander beside streams, and flowers bloom on cactus bushes. All of this contributes to the wild beauty of the dunes. (Photo: vnexpress)
