"The smell and sight refreshes the soul," he said of the plants known in Arabic as wild lavender.
Winter rains brought flooding to parts of western Saudi Arabia late last year, but in northern areas they have brought life to the desert.
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.
Residents of the area kept camels away to stop them eating the flowers that have drawn the sightseers.
