Island hopping A-B-C Islands
As far as I know, there is no commercial boat connection between the the A-B-C islands, anymore. There used to be a ferry, the Chogogo, but they stopped some years ago. I am afraid you will have to fly between Aruba, Bonaire and Curaçao. The flights are short (around 15 minutes), and oompared to thatr the fares may seem high (from Curacao US$82 for Bonaire and US$122 for Aruba).
