Ho Chi Minh City, also widely known by its former name of Saigon is the largest city in Vietnam by population. Under the name Saigon, it was the capital of the French colony of Cochinchina and later of the independent republic of South Vietnam 1955–75. On 2 July 1976, Saigon merged with the surrounding Gia Định Province and was officially renamed Ho Chi Minh City after revolutionary leader Hồ Chí Minh.

Ho Chi Minh City is located in the south-eastern region of Vietnam, 1,760 km south of Hanoi. The average elevation is 19 metres (62 ft) above sea level. It borders Tây Ninh Province and Bình Dương Province to the north, Đồng Nai Province and Bà Rịa–Vũng Tàu Province to the east, Long An Province to the west and the East Sea to the south with a coast 15 km (9 mi) long.

By Air

The city is served by Tân Sơn Nhất International Airport, the largest airport in Vietnam in terms of passengers handled (with an estimated number of over 15.5 million passengers per year in 2010, accounting for more than half of Vietnam's air passenger traffic. Long Thành International Airport is scheduled to begin operating in 2025. Based in Long Thành District, Đồng Nai Province, about 40 km (25 mi) east of Ho Chi Minh City, Long Thành Airport will serve international flights, with a maximum traffic capacity of 100 million passengers per year when fully completed; Tân Sơn Nhất Airport will serve domestic flights

Railway

Ho Chi Minh City is also a terminal for many Vietnam Railways train routes in the country. The Reunification Express (tàu Thống Nhất) runs from Ho Chi Minh City to Hanoi from Saigon Railway Station in District 3, with stops at cities and provinces along the line. Within the city, the two main stations are Sóng Thần and Sài Gòn. In addition, there are several smaller stations such as Dĩ An, Thủ Đức, Bình Triệu, Gò Vấp. However, rail transport is not fully developed and presently comprises only 0.6% of passenger traffic and 6% of goods shipments.

By Boat

The city's location on the Saigon River makes it a bustling commercial and passenger port; besides a constant stream of cargo ships, passenger boats operate regularly between Ho Chi Minh City and various destinations in Southern Vietnam and Cambodia, including Vũng Tàu, Cần Thơ and the Mekong Delta, and Phnom Penh. Traffic between Ho Chi Minh City and Vietnam's southern provinces has steadily increased over the years; the Doi and Te Canals, the main routes to the Mekong Delta, receive 100,000 waterway vehicles every year, representing around 13 million tons of cargo. A project to dredge these routes has been approved to facilitate transport, to be implemented in 2011–14.

Coach bus

Ho Chi Minh City has a number of coach houses, which house coach buses to and from other areas in Vietnam. The largest coach station – in terms of passengers handled – is the Mien Dong Coach Station in the Bình Thạnh District.

Private transport

The main means of transport within the city are motorbikes, buses, taxis, and bicycles. Motorbikes remain the most common way to move around the city. Taxis are plentiful and usually have meters, although it is also common to agree on a price before taking a long trip, for example, from the airport to the city centre. Public buses run on many routes and tickets can be purchased on the bus. For short trips, "xe ôm" (literally, "hug vehicle") motorcycle taxis are available throughout the city, usually congregating at a major intersection. A popular activity for tourists is a tour of the city on cyclos, which allow for longer trips at a more relaxed pace. For the last few years, cars have become more popular. There are approximately 340,000 cars and 3.5 million motorcycles in the city, which is almost double compared with Hanoi. The growing number of cars tend to cause gridlock and contribute to air pollution. The government has called out motorcycles as the reason for the congestion and has developed plans to reduce the number of motorcycles and to improve public transport.

Metro system

The Ho Chi Minh City Metro, a light rail rapid transit network, is currently in the preparation stages, with the first line currently under construction, to be completed by 2019. This first line will connect Bến Thành to Suối Tiên Park in District 9, with a depot in Long Binh. Planners expect the route to serve more than 160,000 passengers daily. A line between Bến Thành and Tham Luong in District 12 has been approved by the government, and several more lines are currently the subject of feasibility studies.
