One of the things to do in Mui Ne is a day tour to the White Sand Dunes. You will find information about the excursion in your hotel. I recommend comparing prices in a couple of places (your hotel and a local travel agency, for instance). Prices may be bargained a little.
There are two different tours, the one that leaves first hour in the morning to see the sun rise, and the one that leaves in the afternoon to see the sun set. The sun set is more beautiful, but be warned that strong winds blow in the area in the afternoons. The winds can make your visit to the sand dunes somewhat annoying.
On the way to the White Sand Dunes, you stop in the fishing port in the picture.
