Over night bus took us from the modern city of Fortaleza to the colonial Sao Louis from where we immediately took a taxi (3hr ride that we shared with our two new Israeli friends) to a small town of Barreirinhas, which is the gateway to the national park Lencois Maranhenses. Here you can observe the traditional north Brazilian rural life with a caveat: poverty moderated by tourist income.
