There isn't a direct ferry any more, there used to be one to Campbelltown but it hasn't run for a few years. You could take the Ardrossan to Arran ferry, drive to the top of Arran and take the Lochranza to Claonaig ferry which takes to to the top of the Kintyre peninsular. You have to prebook the Ardrossan ferry but the Lochranza was just a turn up last time I used it.
www.calmac.co.uk is the website for the ferries serving the area.
