Entry, Exit & Visa Requirements. Generally, all U.S. citizens are required to present a valid U.S. passport when traveling to The Bahamas, as well as proof of anticipated departure from The Bahamas. Those traveling to The Bahamas on a cruise may use another Western Hemisphere Travel Initiative (WHTI) compliant document. However, we strongly recommend visitors obtain a passport before travel in case of an unforeseen emergency that requires a cruise passenger to disembark and return by air.
