The local currency in Bali is the Indonesian Rupiah (IDR). Insider tip: It's recommended to exchange currency at authorized money changers or banks to get the best exchange rates. ATMs are widely available in tourist areas, but it's advisable to carry cash for transactions in more remote locations. While credit cards are accepted at larger establishments, it's always wise to carry some cash. Mobile payment options are not as widely used as in some other countries, so it's best to rely on traditional payment methods.
