Where should I exchange leftover Vietnamese dong before flying from Nha Trang: downtown or Cam Ranh Airport?

If you have a substantial amount of dong left, exchange it in Nha Trang rather than at the airport. Jewelry shops in town are commonly recommended for better rates, while Cam Ranh Airport and hotels tend to offer worse ones.

For a small amount needed for final expenses, using the airport exchange is practical. For a larger balance, exchange the dong in Nha Trang city at jewelry shops instead.

You can exchange leftover dong at the airport before departure, but exchange counters in central Nha Trang are generally the alternative to consider for a potentially better rate.
