Unfortunately, no. At the present time, the only way to get to the other island is by plane. There are no ferry services that can take you to the other islands within the State. You can, however, charter a boat if you wish to do so.

If you’re on a cruise, this is obviously not an issue at all.

I should also point out that things are changing as far as inter-island transportation is concerned. For the past few years, talks about a ferry service between the four major Hawaiian islands have been drumming up some interest, and after a few drawbacks, the Hawaii Superferry service is expected to be operational in July 2007.

From Hawaii Superferry’s website:

Hawaii Superferry will better connect our islands. This will improve the quality of life for everyone.

In July 2007, Hawaii Superferry begins daily ferry service from Oahu to Maui and Kauai. Daily service to Hawaii Island begins in early 2009.

Families will have the alternative to travel interisland with the convenience of their cars including baby seats, surfboard racks, luggage and pets. School groups, halau hula, canoe clubs, and cowboys can travel to events with their vans, equipment, canoes, and horses in trailers.
