I was lucky enough to spend three and a half weeks just gone in South America; two weeks in Peru and one in Bolivia. I took lots of photographs, I uploaded some which are here.
This picture was taken in The Andes between Cusco and Puno, in Eastern Peru. The 10hr train journey climbs at very high altitudes, a peak being at La Raya, which is 14,000ft/4,300m high. The sky was beautiful and the snow capped peaks were spectacular.
