Wide volcanic regions along Chile/Bolivia border, with incredible concentration of unlikely colors in mineral parts, extraordinary variety of colors of lakes, so many special places such as gigantic salt lakes with coral islands covered by huges cactuses, ice covered volcanoes, geysers, hot muds, steam smokes... Wildlife is very rich too, it includes some interesting species of mammals, and also a huge number of species of birds which observation is made easier by their fearlessness to man.
