Dubai is a must-see destination for those seeking the largest and smartest. Mega structures tower above man-made harbors in the tropical waters of the Persian Gulf, all encircled by the golden beaches of the wilderness. This elderly playground, a memorial to the no-limits outlook of its builders and idealists, has changed the country to its doorstep, with a multiethnic society and massive malls stuffed with world-class merchandise and amusement. Visit the local souks in Old Dubai for a more conventional experience, or take a camel trip to the desert.
