Use the mini bus shuttle service is more accountable, professional and well structured currently available to the Ilha Grande and have the peace of mind you will have adequate support and will not be abandoned.
Took far too long to pick up people in Rio. Were delayed to Angra dos Reis so we missed the ferry boat. Driver only language knowledge was portugeese so no info on what to do when delayed.
We used this service as we thought it should be easier than the regular bus service but considering the cost and time spent we now know it was a mistake.
