During the breaking dawn is absolutely, inarguably the best time to tour Namibia’s most stunning spectacle, the vast desert dunes of Sossusvlei. You’re tired – you’ve been up since some unholy hour and have spent part of the night trudging and sliding your way up a mighty dune. But it’s worth it. Easily. The black land’s contours are first silhouetted by purple skies. Slowly, the sun rises, and the towering waves of sand that fill your vision take on new colours. A dune is illuminated, the side facing the sun gloriously refulgent in shades of perfect orange and gold, its other side still black as midnight. As the sun creeps higher, the land becomes a tawny sea of sand, a million ripples on each dune. These are the world’s highest dunes, and a tour here still feels a venture into wonderfully remote territory – an unpeopled world of otherworldly, mesmerising landscapes.
