The local currency in Tanzania is the Tanzanian Shilling (TZS), and while U.S. dollars are widely accepted in tourist areas, it's advisable to carry some local currency for smaller transactions or rural areas. ATMs are available in major cities like Dar es Salaam, Arusha, and Zanzibar, but they can be scarce in remote regions.
Credit cards are accepted at most hotels, restaurants, and safari lodges, but always check beforehand as some establishments may only take cash. Additionally, credit card transactions may incur a surcharge, so it's good to have cash on hand for smaller purchases. It’s also worth informing your bank of your travel plans to avoid issues with card usage abroad.
Tipping is appreciated in Tanzania, especially in the tourism industry. A 10-15% tip is customary in restaurants, and you may want to tip guides, drivers, and porters after a safari or trek.
