How do people cross a desert on foot?


When I walk in the sand at the beach I’m exhausted after just a few minutes. How do people cross entire deserts of sand?

Because a desert isn’t sandy like on a beach. It’s not endless billowy dunes, although a certain amount of area in a desert may be dunes. There’s plenty of surface area of hard rock covered by sand sheets which are basically like walking on a road covered in sand, not trudging through dunes where your feet keep sinking in.
