The Tanzanian currency is the Shilling it cannot be imported into the country and so it is necessary to bring foreign currency with you on safari. US$ Dollars are the best currency to take to Tanzania with the Euro or GB Pounds coming in second and third. US$ Dollars are bar far the safest option with larger notes US$50 and US$100 offering a better rate of exchange. The lower denominations are not popular with the US$1 being difficult to get rid of except as a tip. If you intend to pay for a safari with cash then pay in large dominations to avoid a possible penalty.
Travellers checks are accepted by banks and bureaus, they attract a lower rate of exchange and can be a bit of a hassle; it is better to keep them to a minimum or to avoid them totally. Credit cards [Master and Visa] are more widely accepted now than they were in five years ago. However, if you wish to draw cash against a credit card then try to do this from the banks as many hotels with change heavy commission for the privilege. More importantly let your bank know where and when you travel otherwise you may hit problems once you start using your card in Tanzania.
Visas are available in advance from Tanzanian Embassies or they can be obtained on arrival at border posts or airports. There is a departure tax for Tanzania if you leave by air but this should be included in the price of your ticket.
