Nasser al-Karaani travelled 770 kilometers (480 miles) from the capital Riyadh to see the colorful flowers before they wilt.
"This scene lasts from 15 to 20 days a year, and we come here specifically to enjoy it," the 55-year-old Saudi businessman said.
He unloaded a tent from his four-wheeler and set up base with a group of friends before gathering around a fire for a hot cup of tea.
"This atmosphere makes me feel at ease," said Karaani, wearing a heavy jacket over his traditional thobe gown.
Across the desert, visitors pitched tents and cooked food over open fires.
