By air
Flamingo International Airport (BON) is just south of Kralendijk. Nonstop routes vary by season, but regular links connect Bonaire with Curaçao and Aruba, while long-haul and North American services operate on selected days. Check the operating day before building an itinerary around a particular connection; an overnight in Curaçao is sometimes the sensible fallback.
By sea
There is no dependable scheduled passenger ferry linking Bonaire with Curaçao or Aruba. Cruise ships call at Kralendijk, but they are not useful inter-island transport.
