Ad-Dahna Desert, often simply called Dahna, is a sandy desert in central Saudi Arabia, forming a bridge between the larger Nafud and Rub' al-Khali deserts. It's like a narrow corridor of sand dunes, stretching over 800 miles. Imagine it as a sandy highway connecting two major desert regions. Unlike a solid landmass, it's constantly shifting with the wind. It's more like a sandy river.
