Just visited (March 2013). I have some mixed feelings connected with Rio's nomination. First of all it is one of those places that don't need UNESCO status to be visited. There are not many other big cities in the world with so remarkable lanscape / location. Truely one of world wonders.

But if we see what was really iscribed these are just parts of the city mostly rainforest located inside the town but inscribed as cultural landscape. Little bit strange. Of course Christ on the top of Corcovado is amazing together with Sugar Loaf (in this case is just a huge rock) and less known Botanical Garden (one of the best I have ever been) but other areas were a little bit dissapointing (dirty Copacabana surrounded by modern buildings, similar Botafogo beach - part of Guanabara Bay). Apart from those top atractions there are just modern buildings although perfectly located
