The varied climate and terrain of South America make it a fantastic place to sightsee. The driest place on earth, the Atacama Desert in northern Chile, covers over 40,000 square miles, and includes green salt lakes and two observatories. Further south, see for yourself the growing (not shrinking) Perito Moreno Glacier of Chile, and the famed jagged cliffs around Cape Horn.
On the other side of the continent, you have Fernando de Noronha, a volcanic archipelago off Brazil's eastern coast, a place so beautiful and precious only 400 people a day are allowed to visit. Last - but certainly not least - there is the famous Christ the Redeemer, a statue standing 30 metres tall on the peak of Corcovado mountain, looking down over the iconic city of Rio de Janeiro.
