AL-UYAYNAH, Saudi Arabia — In a makeshift camp under a starry sky, Ghazi Al-Anazi talked about his experience in the fledgling Saudi tourist business. A decade ago, barely in his 20s, he started taking British business associates of his brother to see the wind-carved hills of the Saudi desert.

Now 31, he has a small fleet of S.U.V.s, nearly a dozen employees and a self-taught ability to cater to the whims of visitors from many nations.

“I know what they want to do, and what I need to do about it,” he said, ladling out a dinner of barbecued chicken and Middle Eastern salads to a couple of dozen tourists from France, Ukraine, Malaysia and the United States.
