After a free morning, you'll head out for a leader-led orientation walk around Rio this afternoon. In the evening, there will be another welcome meeting at 6 pm to meet the new members joining your group. Rio locals like to say that 'God made the world in six days, the seventh he devoted to Rio'. In this heaving metropolis, set against Guanabara Bay and surrounded by the slopes of Sugarloaf and Corcovado, it's hard not to be caught up in the passion of the city's residents, known as Cariocas. Known for both the glitz and glamour of Carnaval and the contrasting image of the favelas, Rio is a fascinating and diverse centre of all things colour. Tonight, after your briefing, why not keep the introductions going with an optional welcome dinner with your group.
