Tassili n'Ajjer National Park

Tassili n'Ajjer is a UNESCO-listed desert wilderness where wind and time have carved sandstone into stone arches, pinnacles and surreal rock forests. The plateau holds more than fifteen thousand prehistoric engravings and paintings, recording a green Sahara once roamed by cattle, giraffes and early peoples. Its otherworldly landscapes and dunes make it one of the most extraordinary trekking destinations on Earth.
