The Berry Islands are among the least busy in the Bahamas, and the perfect destination for those looking for the ultimate escape. In part because of the difficulty involved in getting to the islands, and their lack of infrastructure, the resorts in this archipelago are extremely exclusive, catering mostly to wealthy travellers, big game fishermen, and yachters. The largest island is the Great Harbour Cay, a multi-million dollar resort which has hosted the likes of Cary Grant and Brigitte Bardot. The privately-owned Bond's Cay features a bird sanctuary. The beaches in the Berry Islands are known as the best shell-collecting spots in the Bahamas, while the game fishing is some of the best in the world, offering billfish, tuna, grouper, tiger fish, yellow snapper, wahoo, king mackerel, and many more. Every May the islands, nicknamed the 'world's fishbowl', play host to one of the world's top game fishing tournaments. Many of the islands are privately owned, with the wealthy owners using the islands as occasional holiday homes. This has resulted in the Berry Islands having more resident millionaires per unit area than any other place in the world. Several of the islands are leased or owned by cruise companies that drop cruise passengers off on their island for a day as part of their cruise package.
