While Aruba has its own official currency, the Aruban Florin (AWG), the U.S. Dollar is widely accepted and essentially functions as a secondary local currency in 2026. Almost all shops, restaurants, and taxis list prices in both Florins and Dollars, and you can easily pay with U.S. cash throughout the island. The exchange rate is fixed at approximately 1.75 AWG to 1 USD (though shops often use 1.80 for easier math). For 2026 travelers, the "best" currency is actually a contactless credit card with no foreign transaction fees, as the island is highly digitized. However, if you prefer cash, U.S. Dollars are the high-value choice because they eliminate the need for currency exchange at the start and end of your trip. Just be aware that you might receive your "change" in Aruban Florins, which can be a fun souvenir but are difficult to exchange once you leave. For the best value, avoid using ATMs at the airport and instead use bank-affiliated ATMs in Oranjestad or Palm Beach to minimize service fees.
