The legal drinking age in Aruba is 18 years old. This applies to drinking beer, wine, and spirits. Casinos, bars, and nightclubs also require patrons to be at least 18 years old, and they have the right to ask for valid ID to enforce this law. While some say that low-alcohol beverages like beer may be more loosely enforced and accessible from age 16 in some local places, the official legal age remains 18 for all alcoholic drinks combined with legal enforcement in licensed establishments. In summary, if you want to drink alcohol legally in Aruba, you must be at least 18 years old. This is the law and standard policy in casinos, bars, and other licensed venues on the island. This is consistent across several sources including Aruba's official visitor FAQ and local laws.
