The local currency is the Mauritius rupee (MUR). 39 rupees is approximately equivalent to 1 euro, while 43 rupees is approximately 1 pound sterling. That means that 1 rupee is approximately 2 euro cents or pence (more or less). Rupees are available in coins worth 1, 5, 10, 50 cents, and 1, 5, and 10 rupees. Bank notes are available in denominations of 25, 50, 100, 200, 500, 1000, and 2000 rupees. Current exchange rates can be found on the website of the bank of Mauritius.
We recommend only exchanging money once you are already in Mauritius, or withdrawing cash from ATMs in Mauritius once you are there. Exchange in Europe is usually more expensive than this option. All of the larger settlements in Mauritius have at least one bureau de change, as well as banks, and you can shop around for the best exchange rate if you wish. Credit cards are also widely accepted in Mauritius. Visa and Mastercard are the most widely-accepted.
