For U.S. citizens, almost every major Caribbean island allows visa-free entry for tourism. This includes popular destinations like the Bahamas, Jamaica, the Dominican Republic, Aruba, St. Lucia, and Barbados. For stays ranging from 30 to 90 days, you only need a valid U.S. passport and proof of onward travel. Additionally, travelers can visit Puerto Rico and the U.S. Virgin Islands (St. Thomas, St. Croix, St. John) without a passport at all, as these are U.S. territories—though a REAL ID-compliant driver's license is required for the flight in 2026. For non-U.S. citizens, the "visa-free" status varies significantly by nationality. However, the Dutch Caribbean (Bonaire, Curacao, St. Maarten) and French West Indies (Martinique, Guadeloupe) have broad visa-waiver programs for many nationalities, often requiring only an online "ED" (Embarkation-Disembarkation) card registration prior to arrival.
