Hanoi "the city beyond the river" is the capital of Vietnam, located on the Red River Delta which carries its muddy waters to the Gulf of Tonkin. It has long been considered the cultural center of the country. The various museums, embassies and sanctuaries built testify the rich history of the legendary Vietnamese dynasties. This charming and tranquil town on the right bank of the Red River, is close to many of Vietnam's natural wonders such as Halong Bay. In addition to its 3,000 lush limestone islands, the bay contains various natural wonders (illuminated caves, emerald cavities and sandy beaches).
