Money & costs
The official currency is the gourde, and there are 100 centimes to 1 gourde. US dollars are also widely accepted for large purchases. The gourde used to be tied to the US dollar at a rate of one to five, with the result that HTG5 is universally known as one Haitian dollar. When buying something, always check whether people are quoting the price in gourdes or Haitian dollars.
Don’t bother bringing traveler’s checks as they’re near impossible to change. There are ATMs in Port-au-Prince, but they can be unreliable (those in Pétionville tend to be better), so always make sure you have some US dollars as backup. Large businesses, most midrange and all top-end hotels will accept credit cards.
