The Great Sand Sea is Egypt’s last frontier. So why take the kids? This 150,000 square kilometer expanse from Siwa south to Sudan is the third largest dune field in the world. Here, linear dunes run uninterrupted for hundreds of kilometers and reach a height of up to 110 meters. Navigating safe passage across rolling sand dunes is an adventure in the liking of Lawrence of Arabia. And sand dunes are just the start. The Great Sand Sea is home to not one living sole. There is no water in this once lush, green savannah. Fossils, 25 million years in the making, carpet the sand. Sea urchins, seashells and shark teeth are all to be found. But what sets this desert destination apart is the chance to explore. Multi-day jeep expeditions, complete with camping under the stars, are the stuff adventure stories are written about. But before you depart on a trip with kids take note, the difference between a trip to remember and a trip to forget is in the hands of your guide.
