Situated on the other side of the runway to the old marina bay complex it has a fantastic new boatyard and state of the art floating pontoons and real security gates.
This marina is light years ahead of anything you will find in Gibraltar and commands the best views of the historic Rock.
The closest hotel to Gibraltar airport is the hotel Asur right next to the marina.
