I see that Piaui is not the most touristic area of Brasil...Is it easy to travel there if you are alone and without your own car/moto? I am planning to go in January and visit Maranhao, Piaui and Ceara.
Do you know if it is easy to organize a one day trip to Sete Cidades National Park from Parnaiba?
What would be the best base to visit Serra da Capivara? Sao Raimundo Nonato or Petrolina?
Do you have any info on the prices and timetables for buses between Parnaiba and Sao Raimundo Nonato and/or Petrolina?
