ABC islands

From Open Water Swimming Wiki

ABC islands (Aruba, Bonaire, and Curaçao) are the three westernmost islands of the Leeward Antilles in the Caribbean, north of Falcón State, Venezuela.

All three islands are part of the Kingdom of the Netherlands, although they remain outside the European Union. Aruba and Curaçao are autonomous, self-governing constituent countries of the Kingdom of the Netherlands, while Bonaire is a special municipality of the Netherlands.
