You can fly to Porto Seguro from Belo Horizonte, Rio, Sao Paulo, Brasilia, Porto Alegre, Florianopolis and Curitiba (Gol, BRA, TAM) or take a bus from any major Brazilian city. The bus companis are Sao Geraldo and Aguia Branca.
Two ferries cross Buranhem river between Porto Seguro and Arraial d'Ajuda, the passenger ferry and the car ferry. They run every 30 minutes from 7 am to midnight and hourly from midnight to 7 am.
From the ferry dock hourly buses depart to Trancoso from 7:20 am. to 8:30 pm and return hourly from 6:15 am to 10 pm. It takes one hour to get there. Three buses a day travel between Porto Seguro and Trancoso and the journey takes two hours.
Bear in mind that the time tables can always change.
Trancoso is only 26km from Porto Seguro,between Arraial D'Ajuda and Caraiva(look at the map posted previously for a better understand).
There's a motorway access by the BA-001,which was in perfect conditions-NOTE:was,not sure now.
We took a bus from Rio to Porto Seguro,the nearest big city(Sao Geraldo is the bus company name)
At Porto Seguro,we rent a car to start the adventure:from Porto Seguro croosing the Buranhem river by ferry,than through Arraial D'Ajuda city and than getting to Trancoso.
If you are coming from Salvador,we heard the bus company name is Aguia Branca.
We took a flight from Buenos Aires to Porto Seguro (through San Pablo), In Porto Seguro we took a taxi to the ferry quay (R$ 20 => less than Usd 10). There we took a boat to Arraial (R$ 2 => less than Usd 1), and at the ferry station we took a bus to Trancoso (R$ 4 => less than Usd 2). the hole trip is not as terrible as it sounds...
