Bhutanese currency is Ngultrum (Nu.) and is officially pegged to the Indian Rupee. The Indian Rupee is acceptable all over Bhutan with the exception of Rs 500 and Rs 1000 currency notes. Credit Cards have limited acceptability and payment through credit card is accepted mainly by deluxe hotels and few selected Handicrafts establishments only.
There are ATMs in Bhutan but currently they only operate with their respective Bhutanese banks, hence ATM’s cannot be used by visitors. Traveler’s checks / cash are best option if you need additional money.
Cash and Travelers Cheques exchange facility is available for most of the main currencies including the US dollar, Euro, Indian Rupee, Yen, Thai Baht, Pound Sterling, Swiss Franc, Hong Kong dollar, Canadian dollar, Australian dollar, Singapore dollar, Danish Kroner, Norwegian Kroner, and Swedish Kroner.
