Salar de Uyuni is the world's largest salt flat, located in Bolivia. Covering over 10,000 square kilometers, it was formed from the evaporation of ancient lakes. The flat is primarily composed of sodium chloride, giving it a bright white appearance. During the rainy season, a thin layer of water creates a stunning mirror effect, reflecting the sky. This unique landscape is a popular tourist destination, attracting visitors for its breathtaking views and photography opportunities. Salar de Uyuni is also home to various wildlife, including flamingos, and is rich in lithium, an important resource for batteries.
