Brazil was home for two weeks, including the four days of Carnaval, in February.
It was amazing, with great music everywhere, random street parties and one main centre-piece competition at the Samba Drome, where local neighbourhoods try to out-dance, out-smile and out-camp eachother.
The whole thing demands a lot of late night staying-power, and apparently it's fine to spend only one day of your week up and about sightseeing.
This is what happened to our tram during Carnaval. Do visit the interactive section for an all-singing, all dancing film version.
This photo shows a favela and the statue of Christ in the background. You can take guided tours of both places.
Very close to the tram terminal is the city's Catholic Cathedral, with great stained glass stretching the entire length on all four walls.
After Rio, I started my overland bus tour, stopping first at a fishing village called Parati.
Shortly after that we visited what I think is the most impressive set of Brazilian waterfalls that I've ever seen. They straddle the Brazilian and Argentinian border, at a place called Iguacu. The first photo is from ground level, the second from a helicopter.
