The largest of the three islands and a scuba-diving mecca, Grand Cayman has become one of the Caribbean's hottest tourist destinations in recent years. With more than 500 banks, its capital, George Town, is the offshore banking center of the Caribbean. (You won't have any trouble finding an ATM here!) Retirees are drawn to the peace and tranquillity of this British crown colony, site of a major condominium development. Almost all of the Cayman Islands' 55,000-strong population lives on Grand Cayman. The civil manners of the locals reflect their British heritage.
