Everyone who wants to visit Tanzania for holiday are required to obtain a tourist visa. The tourist visa costs 50$ (100$ for US citizens) and is valid for 90 days. The easiest way to obtain the visa is to purchase it in cash (USD) upon arrival in Tanzania. You need a passport valid for no less than six months. You fill in a “visa application form” at the airport/border (some airlines hand you the form to fill before landing), pay the fee and get the visa on spot. The process is simple and fast!
