Since the Abacos are best explored by boat, a waterproof dry bag and polarized sunglasses are non-negotiable for navigating the bright shallows. Pack lightweight, breathable layers and a windbreaker or light rain jacket, as boat rides can be breezy even on sunny days. Water shoes are essential for exploring the limestone caves and rocky shorelines of the various national parks. Because many settlements are small and traditional, bring a casual cover-up to wear when walking through towns like New Plymouth, as appearing in just swimwear is considered disrespectful. Finally, make sure to bring plenty of cash, as while credit cards are accepted at larger resorts, many smaller island bars and ferry services prefer or only accept cash, and ATMs can be scarce once you leave Marsh Harbour.
