Banks and moneychangers in Tanzania
Bank hours in Tanzania are typically 8.30am-4pm Monday to Friday, and 8.30am-1pm on Saturday.You get a significantly better rate for large denomination bills (US$50 and $100 bills) than small ones. Keep your exchange receipts so that when you leave the country you can change your spare shillings back into hard currency. They rarely check, but you never know.
There are ATMs (‘cashpoints’) in all cities and towns in Tanzania and Kenya and these are the best way to get hold of local currency.
