The world's largest uninterrupted sand mass, the Rub Al Khali (Empty Quarter) will blow you away with massive expanses of awesome desert and enormous dunes. It’s a landscape of ever-changing endless dunes made famous by the British explorer Wilfred Thesiger and his Emirati and Omani companions in the 1940s and 50s. Almost a fairytale from ‘1001 nights’, the magnificent Qasr Al Sarab or Mirage Palace is a luxurious oasis in the midst of the desert.  Resembling an old Arabian fortress town nestled in the valley of mountainous dunes, this is actually a five-star resort letting you experience lots of desert activities – dune dawn walks, camel trekking, dune bashing, falconry shows and camp fire barbecues.Perched at the edge of the majestic Rub Al Khali, Tilal Al Liwa is a stunningly secluded desert hideaway. There are restaurants, a sparkling outdoor pool, and a full range of desert activities. Considered by many to be the world's tallest sand dune, Tel Moreeb is over 300 metres high and the 50 degree incline to the top makes it a prime destination for motor sports enthusiasts. Every winter, the region's most powerful four wheel drivers and quad bikers compete in the Moreeb Hill Climb event, which is part of the Liwa International Festival.
