One of the major attractions of Bolivia is the Salar de Uyuni, the worlds largest salt flat. And it's popular for a reason. I took a 4-day tour by jeep from Uyuni to the Chilean border. We started with a quick visit to the local train graveyard, then headed out on the saltflats. We spent the first night in a village on the slopes of the Tunupa volcano, a 5400m mountain we hiked at sunrise the next morning.The scenery is fascinating. Every natural reaction is to think that something that big and flat is a lake. Which I guess this is, but I repeatedly had to do a double take when looking up and seeing that everything was white. And it's hard to understand from the pictures how big it is. The flat is 10,582 km² (4,085 square miles) and it took hours to drive across. Full album here.
