Vaccinations are not currently required for United States citizens entering or leaving Tahiti. Consult your physician or travel agent prior to departure for any updates. The tropical sun can be deceptively penetrating, so be sure to use a good, waterproof sunblock to protect you skin from overexposure. Bring a converter to charge camera batteries and to run other 110v items such as hair dryer, irons, etc. Film and batteries are extremely expensive.
Powder drinks to mix with water save on softdrinks.
Snacks to munch on during the day. Zip lock bags to keep items from getting wet. Casual, informal dress is standard in Tahiti. Lightweight, washable cottons are suggested for greatest comfort. We also recommend taking along a couple of swimsuits, rubber-soled water shoes for walking on coral, hat or sun visor, sunglasses, and waterproof bag.
