Calico Jack's is the bar on the small island off Half Moon Beach just a few minutes before (by car) you reach Green Island.
Half Moon recommends that you call them first to make sure that Jack's is open. There is a cost to have their boat take you to the island. They can also arrange a pick up and drop off for you when you call. The cost for a water taxi such as Vincent to get you there will be substantially higher than taking their shuttle or a taxi. But the view you would have would be a very enjoyable experience from the water!
