Chile’s Atacama Desert, paradise for sand dune hiking and stargazing, is world’s driest
- A hike through part of Chile’s Atacama Desert reveals seas of sand dunes, some of the world’s best stargazing spots, and surprising meals

Crescent-shaped sand dunes rise and fall steeply, some up to 100 metres (330 feet) high.
The sun beats down on this part of northern Chile and it is exhausting to walk. Your boots sink deep into the golden sand.
But it is worth it, when you reach the ridges of the sand mountains near Copiapó and are rewarded with the sight of a dune landscape that never seems to end.
South America’s answer to the Sahara, the southern part of the Atacama Desert is known as the Sea of Dunes (“Mar de Dunas”), with those dunes spanning 335 square kilometres (129 square miles).

At 550 metres, El Medanoso is one of the highest dunes on the continent. People snowboard down its steep slopes, while adrenaline junkies race through the sandy mountains in four-wheel-drive cars.
