There is no doubt that it is worth visiting Sugar Loaf Mountain in Rio de Janeiro, Brazil.
Unlikely the Corcovado summit though, there is no impressive statue close by to look at. On the other hand, on Sugar Loaf summit there are breath-taking views around you, and rather close, if compared to Corcovado. Sugar Loaf complements the visit of Corcovado, and both are a must-visit.
Needless to say, the views are better on a clear and blue sky day. Make sure to go visit it at non busy time to avoid standing in line much.
