My tour guide Mike was very well informed, patient with all my questions, and really just a nicely personable companion to help me with my first exploration of the Brasilia architectural marvels.
I’m happy that I tried TripAdvisor for suggestions; Mike made this trip very memorable

The tour guide is nice but he just learnt English 3 months. He’s like a Uber driver, couldn’t give any introduction… So sorry I do not recommend to waste this money…

This tour gave us a decent introduction to some of the major architectural sites in Brasilia. Although the posting says water is provided, we received none, so bring your own. The tour is posted as being presented in English, but if our experience is any indication, it is multilingual and depends on the makeup of the group. In our case we were two English speakers out of a group of ten, so the majority of the information was given in Portuguese with shorter asides to us in English. The English of our guide was excellent. We were given ample time to walk around the national cathedral, three powers plaza, and other stops. We didn’t receive some information that would have seemed obviously of interest, that we read about later on our own. For example, at the Santuario Dom Bosco, we learned about construction details, but nothing about the interesting story behind how Dom Bosco’s dream led him to be considered a patron Saint of Brasilia although never having set foot in Brazil. Read about the major landmarks before going on this tour so you know some of the history, and can ask questions.
