From Baker drive about 35 miles north to Harry Wade road. Take Harry Wade road 6 miles then turn on Saratoga Springs road, you'll see the dune field to the south.
Sand dunes can be the most peaceful place on the planet, if you can find the right ones. All of them have the magic ability to soak up sound and render the landscape breathlessly quiet. But few of them have the same feeling of pristine isolation as the Ibex Dunes in the southern part of Death Valley. Every time I visit them I experience peace and quiet in a whole new way.
