As the saying goes in Nevis..."Getting to Nevis maybe hard-but leaving is even harder", and honestly that about sums it up. The Nevis airport (Vance W. Amory International Airport) is modern but small, however it does accommodate small jets and turboprop planes. (Airport code NEV)
For American guests to Nevis: American Eagle flies direct to Nevis from San Juan, Puerto Rico (Airport code SJU). Or you can get to Nevis by taking US Air to nearby St. Martin (Airport code SXM) or Antigua (Airport code ANU). (If you arrive via St. Martin, Winair will take you from there to Nevis. If you go via Antigua, you will take LIAT or Carib Aviation to Nevis.)
Flying from Eastern Canada? From December to March you can fly nonstop Skyservice charter from Toronto, Canada (Airport code YYZ) to Saint Kitts (Nevis' Sister Island, Airport code SKB). The flight arrives in Saint Kitts at noon, and then you can catch one of the local ferries over to Nevis. Or there is a charter to St. Maarten on Saturdays, and you can catch a connecting flight to Nevis. Alternatively you could take an Air Canada flight on Saturdays to Antigua, and then the next morning fly LIAT to Nevis.
Flying from Europe? There are regular flights on British Airways and Virgin Atlantic into Antigua. Connect with LIAT or a charter flight with Carib Aviation and you'll be in Nevis in no time! Excel Airways currently runs flights to St. Kitts on Saturdays out of Gatwick (Airport code LGW), but starting in November, that once weekly flight will move to Mondays.
Passengers who fly into Saint Kitts (more flights into Kitts) instead of directly into Nevis, will need to either take a Public Ferry (the cost is only US $6.00 each way, see the ferry schedule), or ask about the Four Seasons launch (US $95, and note that their guests take preference), or one can order a water taxi (there are several available on request.) from Nevis Water Sports. However, it is worth noting that very few water-taxi captains are willing to do this run after dark.
