The currency in Tanzania is the Tanzanian shilling (Tsh or TZS). There are notes of 200, 500, 1000, 5000 and 10,000 shillings in circulation. Coins are of 1, 5, 10, 20, 50, 100 and 200 shillings. The exchange rate is not stable so is best to check shortly before departure through a resource such as www.oanda.com
It is not possible to buy Tanzanian shillings in advance, just as it is not possible in Kenya to buy dollars and euros. In many places in Tanzania, it is possible to use ATMs for withdrawals. Keep in mind that sometimes the power fails, preventing you from using the ATMs.
In Tanzania, credit cards are hardly accepted anywhere. You can only use it in case of emergency, at some supermarkets (in combination with your passport for identification purposes) and at expensive hotels. Never exchange money on the black market because the chances are that you get your hands on counterfeit money. Try to get small denominations of Tanzanian shillings when you change money, that makes things easier because there are many places that will often not have change. You might also take a part of your money in the form of traveller's cheques, these are insured against theft and loss. Travellers checks are not always convenient, and you can wait a long time in the bank to get them cashed.
We recommend taking 2/3 of your pocket money in euros and 1/3 in U.S. dollars. With dollars you can more easily pay the entrance at the parks (Hell's Gate - and NP Nakuru in Kenya). Please note that dollar bills before 2004 are not accepted.
The allowance recommended by us is a minimum for your meals, drinks, optional excursions, entrance fees, local airport taxes and gratuities. The amount you actually spend will depend a great deal upon your own habits which is why souvenirs are therefore not included.
