Home to the largest sand desert on earth, Saudi is full of adrenaline-packed excursions and history-inspired activities. There’s no better time to explore Saudi's sands than during the country’s mild winters. For those who love a thrill, Riyadh’s sand dunes offer sandboarding, dune bashing and other adventures. Or find serenity through activities such as kashta, a true Arabian experience that invites travelers to sleep among the sand dunes and beneath the stars. (Be sure to look for seasonal constellations like the Winter Hexagon.) For the unexpected, venture to one of Saudi’s desert lakes to discover lush vegetation surrounded by vast expanses of red sand and iconic desertscapes.
