Make a trip to the past in the streets of Ouro Preto, this historic city has amazing "Mineira" cuisine, amazing barroco churches and the wondeful architecture of it's golden years of Colonial Brazil, make sure to visit Gold Mines (the best one is located at the Passagem de Mariana)
The whole city is fun. Even in the summer! Unless you’re out hiking in the canyons, you’re in your car or in a building with AC. So complaining won’t cool you down. Visit and enjoy!
