We are now in Curitiba (pronounced Curichiba) a pleasant university city, 6 hours by bus from Sao Paulo. It´s a lot cooler here as it is the highest city in southern Brazil and the temperature was 13 degrees centigrade when we arrived last night (compared with 37 degrees in Rio a few days ago!). There are many colourful buildings and the streets seem clean and safe. Tonight we take a night bus to Foz do Iguazu, which takes 10 hours.

We have just realised we haven´t said anything about our tour group yet. Our guide Rebecca is Australian and our six other group members are all Brits apart from one Irish girl. All of us are within about 10-12 years of each other in age so that´s quite good and we all get along well (so far!).
