You'll find many things to do and sites to discover in Rio. Pao de Acucar (Sugarloaf Mountain) is a location where wide ranging sights of Rio and beyond can be relished. By far the most impressive feature may be the green peak which projects out over the city with excellent 360 degree sights of Rio de Janeiro. Aim to get there previous to Sunset to have an amazing twilight view of the city and very soon later a breathtaking night time view of Copacabana.
