Getting to Nevis
It may be more convenient and economical to fly to St. Kitts (SKB), then take a water taxi right to Oualie Beach pier (contact Wincent Perkins at Islander Watersports, 869-662-7081, dtccaribbean@hotmail.com). Or take a government ferry to Charlestown; it is a pleasant one-hour crossing.American has direct flights from Miami and from New York JFK to St. Kitts.
See the Nevis Tourism Authority site for a more detailed list.
