The Cua Luc Straits divide Halong City into 2 parts: Bai Chay and Hon Gai. For the time being, in order to cross the straits, visitors have to take a ferry boat. In the near future, a suspension bridge of 903m in length will be built to connect the 2 sides of the city. Hon Gai used to be a coal-exporting port and is now one of the most important commercial centers for transporting passengers and goods in northeastern Vietnam. Bai Chay is a low gently sloping range of hills running along the sea for 3kms. It was planned to be a windward seaside resort in the French colonial time. Now with many international standard hotels, recreational parks, green trees and white sand, Bai Chay has become one of the most beautiful beaches in Vietnam
