Have you known this?
The main languages spoken are Swahili and English. Locals appreciate any Swahili you can speak!
The local currency is Tanzanian is shillings. U.S. dollars, Euros, and credit cards may be accepted by several stores and hotels, but the exchange rate is better with shillings. ATM’s are only available in larger towns like Moshi and Arusha. Most people bring the bulk of their money in travellers cheques, but will also bring some cash including smaller bills. For travellers cheques, there is often a $1/cheque fee and you can only change it at the bank, and the exchange rate is better for $100 cheques. When you exchange money, be sure to get some smaller bills as change is not always available.
The roads are almost like in the Philippines especially those roads in the countrysides.
