Rub Al Khali — The Empty Quarter

Salalah, Dhofar

The largest continuous sand desert on earth, stretching across Oman's western border into Saudi Arabia and Yemen. Enormous dunes, absolute silence, and no phone signal. Accessible from Salalah with a guide and a 4WD. Not a day trip — this is expedition territory.
