Best time to visit the Uyuni Salt Flats in Bolivia: See the amazing mirror effect: December – January – February

The biggest salt flat in the world was created thanks to a huge Bolivia salt lake that dried up, leaving us with the largest reflecting surface, which can be seen during the rainy season. So, if this is your main purpose, consider planning your trip between January and April, when, thanks to the rain, you will be able to admire the overwhelming beauty of the mirror effect.

The largest salt flats on earth, the Salar de Uyuni spans over 10.5 kilometres (4,000+miles).⁠
The Salar con be visited in both the rainy and the dry season. During the Rainy season (November to March) a layer of rainwater creates a mirror-like surface as smooth as glass. Like in the photo.⁠ ⁠📸 @thegipsyjourney

In case you are hunting for the most amazing natural mirror in the world, this is the best time to visit Uyuni Salt Flats in Bolivia. As you can imagine, this is also the time when the majority of tourists come to this area. So, expect it to be crowded.
