U.S. citizens are not allowed to travel directly to Cuba without a U.S. Treasury Department license. Travel is sometimes arranged through a third country instead. Once in Cuba, U.S. citizens will encounter no restrictions. All travelers must be aware that hurricanes may strike from June until November. Cuba has a very effective hurricane response operation. If planning to visit during an important carnival, make arrangements for your accommodations and rental car in advance; the supply of rental cars sometimes runs out. Be aware that if you have dietary restrictions, travel could be problematic as there is little variety in food in Cuba, and if you take regular medicines, bring them all with you. In fact, if you need anything in particular while you travel, bring it with you. There is very little to buy in Cuba.
What to Pack
Pack everything you think you might need while traveling in Cuba. All consumer products in Cuba are either non-existent or scarce. Bring all medicines, special toiletries, contact lenses, special foods, reading materials, clothes, and sun protection. Opticians do exist, but pack a prescription just in case. Sun screen is available at resorts, but you'll pay exorbitant prices for it. Baseball caps can be found in some stores but proper sun hats can not. Bring sturdy luggage and locks; these cannot be replaced. Also, bring electricity adaptors and any unusual batteries.
