The No. 1 "do not leave home without" item is identification, specifically ID with a picture. In fact, travelers will not get past immigration without a passport and airline ticket/boarding passes. They should also bring additional forms of ID such as a driver's license or identification cards. Additionally, visitors are required to give the address of where they will be staying in Barbados to immigration control. Some people may also need a visa, depending on their country of origin.
Barbados is renowned for its hot temperatures, so travelers will need to pack light and comfortable clothing. Ideally, clothing should be made of cotton, khaki, linen or any other lightweight materials. Some essentials include: shorts, T-shirts, capri pants, short-sleeve shirts, flip-flops, sandals, sneakers, a beach bag, bathing suits, hats and sunglasses. The temperature drops slightly at night, so you might want to bring a light sweater or jacket, as well as a dress for women and a nice sport shirt for men, for going out on the town for dining or dancing.
There are numerous tropical wonders in Barbados that even the best of memories can't recall. Pack a camera along with accessories and film (if not using digital) in carry-on luggage. It is also a good idea to bring an underwater disposal camera to capture exotic and tropical sea life or outdoor activities such as snorkeling.
Essentials such as any medications, vitamins, shampoo, face wash, toothbrushes, razors, deodorant, feminine items, lip balm (with sun protection), aloe vera, bug spray and of course sunscreen should be packed for a Barbados vacation. Most of these items can be purchased on the island, however, they are usually significantly more expensive than in the U.S.
Even though the Caribbean is renowned for its hot, sunny days, it does rain in Barbados. Instead of purchasing an umbrella, pack a compact and light model. A waterproof hooded jacket or poncho can also be beneficial.
Of course the main point of a Barbados vacation is to enjoy the picturesque beaches and relax. Pack some recreational materials such as books, magazines and an iPod to unwind on the stunning island.
