Salar de Uyuni is the largest salt flat in the world, a huge sea of white salt sitting high in the Bolivian Andes. It stretches so far and so flat that the ground looks like it goes on forever.
It is famous because after rain a thin layer of water turns the whole flat into a giant mirror that reflects the sky and clouds. People come from all over the world to take magical photos and watch sunsets that seem to float in the air.
In the rainy season, from December to March, a thin sheet of water covers the salt and turns it into the biggest natural mirror on Earth. Standing on it feels like walking on the clouds.
The salt flat sits very high in the mountains, so days can be sunny and bright while nights turn cold and starry. Warm clothes and sunglasses help you enjoy it comfortably.
Workers scoop the salt into neat white cones to dry, and a rocky island in the middle is covered in giant old cacti. It is a fun and surprising place to explore.
