Robert L. Bradshaw International Airport: Take an authorised yellow-plate taxi from the airport stand. Downtown Basseterre is only about 4–10 minutes away; expect roughly US$11 or more depending on destination, luggage and time. There is no airport rail link and no clearly useful dedicated airport bus for most arrivals—do not pay for a pre-sold shuttle when a taxi is this short.
Port Zante cruise terminal: The central grid—The Circus and Independence Square—is walkable from the pier in roughly 10–15 minutes through the duty-free area. Do not take a taxi for downtown; save one for an island excursion or beach.
Basseterre Ferry Terminal (from Charlestown, Nevis): Several passenger ferries run between Charlestown and Basseterre daily, particularly in early morning and late afternoon. Use it for Nevis rather than treating it as an organised tour; check the day’s sailing times and fare locally, because service is not a clockwork commuter schedule.
