Copacabana Beach (Rio de Janeiro). 'The Copacabana experience is about many things: rising early and going for a run along the sands, playing in the waves on a sun-drenched afternoon or whiling away the evening over cocktails and appetizers at a beachfront kiosk. Regardless, you’ll probably notice that incredibly seductive view: 4km of wide, curving sands framed by Rio’s ubiquitous green peaks.' http://www.lonelyplanet.com/brazil/rio-de-janeiro/sights/beach/copacabana-leme-beach
Salar de Uyuni in Potosí, Potosí- During the rainy season, the world’s largest salt flat becomes the world’s largest mirror. The Salar was born when several prehistoric lakes joined into one. The salt flat is so reflective, it’s used to calibrate satellites.
The Salar de Uyuni in Bolivia is the worlds largest salt flat. The salt is over 10 meters thick in the center. In the dry season, the salt planes are a completely flat expanse of dry salt, but in the wet season, it is covered with a thin sheet of water that is still drivable.
