Great Sand Dunes of the World
Shaped grain by grain by the wind, sand dunes are always moving, always changing. Some rise higher than skyscrapers, some hide lakes between them, and some glow red, gold or orange as the sun moves across the sky.
This guide takes you to five remarkable dune landscapes on four continents: Sossusvlei in Namibia, the Dune du Pilat in France, the oasis of Huacachina in Peru, Great Sand Dunes in the USA and Erg Chebbi in Morocco.
How to use the app: read the fact of the day, open any dune to play with the light and compare its height with famous landmarks, test yourself with the quiz, and put two dunes side by side.
