From the top of the hill where the church of Santa Efigênia is located there is a fantastic view of the center of town.
There are many to choose from, but my favourite church in Ouro Preto has to be São Francisco de Assis.
In front of the church of São Francisco de Assis there is an unmissable crafts market.
Conde de Bobadela street is perfect for a stroll, a meal and a some shopping here and there.
The interior of the church of Matriz da Nossa Senhora do Pilar is a must (photography not allowed).
And for those with their own means of transportation, it is well worth going as far as the church of Santa Efigênia.
