Can foreign UnionPay cards be used for payments in Da Nang, or should travelers withdraw Vietnamese dong instead?

A Rosselkhozbank UnionPay card was declined at Ba Na Hills, so bring cash in Vietnamese dong for tickets and other spending at the resort.

Travelers treat UnionPay as a backup rather than a guaranteed payment option; after arrival, it is sensible to withdraw or exchange some money into VND.

Travelers may try paying directly with a Rosselkhozbank UnionPay card, but there is no confirmed list of reliably accepting merchants in Da Nang. Cash dong remains the safer option.
