Corcovado in the Marvelous City of Rio
If you go to Rio, you MUST go to Corcovado. The view is breathtaking, and the atmosphere is great. Rio de Janeiro is set on such an interesting landscape that going up to Corcovado gives you a perspective of the city that you would otherwise miss. It's just a great place and like 'icing on the cake' for any trip to Rio. I recommend a trip to Corcovado over a trip to Sugarloaf. If on foot, I would suggest taking a taxi (available at the base of the road) up to Corcovado -- taxi drivers will usually let you stop at a couple viewpoints 1/2 way up the drive, and they will know Rio -- i.e, they can offer plenty of advice for anything else you might want to do in Rio. Further, the trolley (the other means for travelling up to Corcovado) was help up (no kidding!) a few years back by thugs, I don't know if any changes have been made to make sure the trolley is more secure today.
