What currency should I bring for Madagascar?
Antananarivo (Tana) is the only place to exchange currency. You can do this at the airport, hotel (rate not so good) or official bureaux de change outlets. Travellers cheques can be swapped in Tana, but you have to show your passport and your proof of purchase and it is a time consuming affair! There are some ATMs in Madagascar where you can withdraw Ariaries, again these tend to be in the larger places.
We would advise you to bring sufficient cash, preferably in Euros or US Dollars and change this when you arrive into Tana.
