Definitely the most unusual landscape and environment I have been in during my trip in South America.
The 3 day tour from San Pedro de Atacama in Chile to Uyuni in Bolivia, passed through many extreme varieties of land, climate, existence and altitude. In the first day climbing from 2,400m up to 4,800m and spending the night at 4,200m, severe headaches were felt, but I got away lightly, un-like others. Putting the altitude sickness in the back of my mine, we had to experience every second of this incredible almost untouched environment. Tourism has still yet to fully make its foot print on the vast land, partly because its sheer remoteness but also due to it being Bolivia and behind the times and sheer lack of money.
Little can survive in these conditions, apart from the bizarre rabbits, foxes and various breeds of Flamingos which stand like figurines in the acid waters without moving an inch from the extreme winds. An amazing 3 days exploring this barren land so beautiful photos do not quite capture the pureness of what was experienced.
