Where is Vietnam? The short answer
Vietnam is in Southeast Asia, on the eastern coast of the Indochinese Peninsula. It borders China to the north, Laos to the west and Cambodia to the southwest, with the South China Sea to the east and south.
The country runs from about 8°34'N to 23°24'N and 102°08'E to 109°28'E. That latitude span is why a single "best time to visit" answer does not exist.

Vietnam is slightly smaller than Germany and a little larger than Italy. The population passed 100 million in 2023, which makes it the third most populous country in Southeast Asia after Indonesia and the Philippines.
Vietnam on the map: borders, neighbors and the sea
Land borders
Three countries touch Vietnam by land. China lies to the north along roughly 1,300 km of border. Laos runs down the western side for about 2,160 km. Cambodia meets the southwest for about 1,230 km.
Foreigners can cross at a limited set of international checkpoints, and not every crossing accepts the e-visa. Confirm your specific port before booking transport.
The coast and the sea
Vietnam has about 3,260 km of mainland coastline and more than 2,700 islands. Locally the water is called Biển Đông, or East Sea. English-language maps usually say South China Sea.
The Paracel (Hoàng Sa) and Spratly (Trường Sa) island groups are disputed, and maps showing the nine-dash line are politically sensitive inside Vietnam. None of this affects a normal tourist itinerary, but printing or displaying the wrong map can cause friction.
Who is near, who is not
Thailand does not border Vietnam. Laos and Cambodia sit between them, which is why the overland route from Bangkok takes a full day or more.
Hainan in China is across the Gulf of Tonkin. The Philippines and Malaysia lie across the sea. From Hanoi or Ho Chi Minh City, direct flights reach Bangkok in about 2 hours, Siem Reap in about 1 hour 15 minutes, Luang Prabang in about 2 hours and Hong Kong in about 2 hours 30 minutes. That makes Vietnam a practical hub for a multi-country trip.
Shape and size: why distances surprise first-time visitors
Vietnam is an S-shape. It stretches about 1,650 km from north to south, narrows to roughly 50 km around Quang Binh province, and widens to about 600 km in the far north.
The country has two rice baskets, the Red River Delta in the north and the Mekong Delta in the south, joined by a thin central strip. In between lie the northern mountains, the Truong Son range, the Central Highlands and the Mekong plain.
Hanoi sits in the north, not in the center. Da Nang is the geographic midpoint. The straight-line distance from Hanoi to Ho Chi Minh City is about 1,150 km, and the road route is roughly 1,700 km.
Travelers routinely book a 5-day north-to-south trip. That is about 340 km of travel per day. It does not work.
North, Central and South: what each region is like
Northern Vietnam
Hanoi, Ha Long Bay and Lan Ha Bay, Ninh Binh with Tam Coc and Trang An, Sapa and the far north including Ha Giang. The north has four seasons, a genuinely cool winter and near-freezing nights in the mountains. Allow 4 to 6 days minimum.
Central Vietnam
Phong Nha, Hue, Da Nang, Hoi An, the Cham Islands, Quy Nhon and Nha Trang. This is the heritage and beach belt, and also the typhoon belt. Allow 5 to 7 days if you include Phong Nha and Hue.
Southern Vietnam and the Mekong
Ho Chi Minh City, Cu Chi, the Mekong Delta, Phu Quoc, Con Dao and Dalat in the highlands. Hot all year with a clear wet and dry season. Allow 4 to 6 days, more with an island.
Official regions versus how travelers divide the map
Vietnamese statistics use six socio-economic regions, and older sources list eight. For planning, the North, Central and South split is what matters. It maps onto climate, food and transport far better than the administrative version.
| Region | Key places | Character | Best months | Minimum days |
|---|---|---|---|---|
| North | Hanoi, Ninh Binh, Ha Long, Sapa, Ha Giang | Four seasons, mountains, capital | Mar-Apr, Oct-Nov | 4-6 |
| Central | Phong Nha, Hue, Hoi An, Da Nang, Nha Trang | Heritage, beaches, typhoon belt | Feb-Aug | 5-7 |
| South | Ho Chi Minh City, Mekong, Phu Quoc, Dalat | Hot year-round, delta and islands | Dec-Apr | 4-6 |
The 2025 province mergers: why older maps are wrong
In 2025 Vietnam reduced its provincial-level units from 63 to 34: 28 provinces and 6 centrally governed cities. The district level was abolished entirely. Most travel sites still cite the old figures.
What changed for a traveler is paperwork, not geography. Addresses on tickets, hotel listings and Google Maps labels may not match what you booked.
| Place travelers know | Old province | Current unit |
|---|---|---|
| Hoi An | Quang Nam | Da Nang city |
| Vung Tau, Con Dao | Ba Ria-Vung Tau | Ho Chi Minh City |
| Nha Trang | Khanh Hoa | Khanh Hoa (enlarged) |
| Da Lat | Lam Dong | Lam Dong |
| Phu Quoc | Kien Giang | An Giang |
| Ninh Binh | Ninh Binh | Ninh Binh (expanded) |
The cities and sights have not moved. Only the administrative labels around them changed. Verify current names before publishing dates, because secondary details are still being updated.
Where things are: a place finder for popular destinations
Around Hanoi
Ba Dinh Square sits in central Hanoi and holds Ho Chi Minh's Mausoleum, which closes for annual maintenance, so check dates before you go. Hoan Kiem Lake and the Old Quarter are a short walk away. Ba Vi National Park is about 50 to 60 km west of the center, 1.5 to 2 hours by road. Co Loa Citadel is about 20 km north. Ninh Binh and Tam Coc are about 90 to 100 km south, 2 to 2.5 hours. Ha Long Bay is about 150 to 170 km east.
Ho Chi Minh City and the south
Dong Khoi Street runs through District 1 as the old French-era shopping street. Ben Thanh Market is also in District 1, with a separate night market outside. The Cu Chi tunnels are about 60 km northwest. Can Gio and its Monkey Island are about 50 km southeast. Mekong Delta towns such as My Tho and Can Tho are 1.5 to 3.5 hours by road.
Central coast and highlands
The Cham Islands sit about 15 km off Hoi An, reachable by speedboat, and rough seas cancel crossings in the wrong months. Hoi An, My Son, Hue's Imperial City, Phong Nha and Da Lat fill out the center and highlands.
Clearing up "Monkey Island"
At least three places carry the name. Can Gio near Ho Chi Minh City, Hon Lao near Nha Trang, and Cat Ba's Monkey Island in Lan Ha Bay. They are hundreds of kilometers apart. Do not feed or handle the macaques at any of them.
Farther afield
Phu Quoc, Con Dao, Sapa, the Ha Giang loop, Cat Ba and Mui Ne all sit outside the main north-south corridor and each need a dedicated detour of at least 2 days.
How to get to Vietnam
Flight times
Direct flights from Western Europe to Hanoi, Ho Chi Minh City or Da Nang run about 11 to 13 hours. From the US West Coast expect 15 to 17 hours with one stop. From Australia, about 8 to 9 hours. From Bangkok, Singapore, Seoul or Tokyo, 2 to 6 hours.
Time differences from Vietnam: Paris +5 or +6, London +6 or +7, New York +11 or +12, Los Angeles +14 or +15.
Long Thanh airport near Ho Chi Minh City is under development. Do not plan around it until it opens.
Entry rules in brief
The e-visa covers up to 90 days, single or multiple entry, at USD 25 or 50. A list of mostly European nationalities gets 45 days visa-free. Phu Quoc has its own 30-day visa-free policy. Passports need at least 6 months of validity.
Policies change often. Check the official e-visa portal before booking, and see the dedicated visa guide for the full process.
Overland entry
From Cambodia: Moc Bai, Xa Xia and the Mekong river route. From Laos: Lao Bao, Cau Treo and Tay Trang. From China: Lao Cai, Dong Dang and Mong Cai. Bus "packages" sold at guesthouses are a common source of scams, and not every crossing accepts the e-visa. Confirm both before you travel.
Getting around: distances and travel times
| City pair | Distance | Flight | Train | Bus | Price (VND) |
|---|---|---|---|---|---|
| Hanoi - Ho Chi Minh City | 1,150 km | 2h | 30-33h | Not advised | 1,200,000-3,500,000 (USD 48-140) |
| Hanoi - Da Nang | 760 km | 1h 20m | 15-17h | 14-16h | 700,000-2,000,000 (USD 28-80) |
| Da Nang - Hoi An | 30 km | - | - | 45m | 100,000-200,000 (USD 4-8) |
| Hanoi - Ha Long | 160 km | - | - | 2.5h | 200,000-500,000 (USD 8-20) |
| Hanoi - Ninh Binh | 95 km | - | 2h | 2h | 150,000-400,000 (USD 6-16) |
| Ho Chi Minh City - Can Tho | 170 km | - | - | 3.5h | 150,000-350,000 (USD 6-14) |
| Ho Chi Minh City - Da Lat | 300 km | 1h | - | 7h | 250,000-600,000 (USD 10-24) |
Three honest points. Domestic flights are cheap but delays are common in typhoon season. Sleeper trains are slow but the Hue to Da Nang stretch is genuinely scenic. Motorbike touring needs the correct license, insurance and, in border areas, a local permit.
Book an open-jaw route: arrive in Hanoi, leave from Ho Chi Minh City. It avoids backtracking and saves a full day.
Climate by location: when to go to each region
There is no single best month. The north-south span creates different seasons at the same time.
North
Best in March to April and October to November. December to February is cold and misty. June to August is hot with heavy rain.
Central
Best in February to August. Typhoon and flood risk peaks from roughly September to November, especially in Hue, Hoi An and Quang Binh. Flexible plans and insurance matter here.
South
Best in December to April. May to October brings short heavy afternoon showers, not constant rain.
Highlands and islands
Da Lat is cooler year-round. Phu Quoc is best from November to April. Con Dao runs roughly December to August.
| Month | North | Central | South |
|---|---|---|---|
| Jan-Mar | Cold, misty | Cool, mixed | Dry, hot |
| Apr-Jun | Warm, good | Good | Hot, wet start |
| Jul-Sep | Hot, rainy | Hot, typhoon risk | Wet |
| Oct-Dec | Cool, good | Wet, typhoon peak | Dry, best |
Hanoi's winter average is not 7 to 8°C. That range describes the coldest nights. Daytime averages sit closer to 17 to 20°C.
Where Vietnam's history happened: the war, the capitals and the oldest cities
Where was the Vietnam War fought?
Across the whole country and into Laos and Cambodia. The 17th parallel and Ben Hai River divided North and South at the Demilitarized Zone in Quang Tri. The Ho Chi Minh Trail ran along the western border. Major visitor sites include Hue, Khe Sanh, Vinh Moc, Cu Chi, Saigon and Hanoi.
Unexploded ordnance remains in central provinces. Stay on marked paths and use only established sites.
The two capitals
Hanoi served as the capital of North Vietnam and then of the unified country from 1976. Saigon was the capital of South Vietnam until 1975. Hue was the imperial capital from 1802 to 1945.
Oldest city or town
It depends on the definition. Hanoi has been a capital since Thang Long in 1010, and Co Loa dates to the 3rd century BC. Hoa Lu was the first capital of an independent Dai Co Viet in 968. Hoi An is the best-preserved old trading port.
Safety, health and practical risks tied to geography
Vietnam is generally safe for visitors. The main risks are road traffic, motorbike bag snatching in Ho Chi Minh City and Hanoi, taxi and ride scams, and typhoons and floods in the central region.
Dengue risk peaks in the wet season, so use repellent. Tap water is not safe to drink. Air pollution in Hanoi can be severe from October to March, so check the AQI. Health advice should come from your national health authority.
For background, noncommunicable diseases such as stroke and ischemic heart disease account for most deaths nationally according to WHO data. That is context, not a travel risk.
Buy insurance that covers motorbike use and medical evacuation.
Costs and a simple way to plan routes by location
Budget travel runs about 1,000,000 to 1,500,000 VND (USD 40 to 60) per day. Mid-range runs 2,000,000 to 3,500,000 VND (USD 80 to 140). Exchange rates hover around 25,000 to 26,000 VND per USD.
Three route templates driven by the map:
- 7 days in the north: Hanoi, Ninh Binh, Ha Long or Lan Ha.
- 14 days north to south: Hanoi, Ninh Binh, Hue, Hoi An, Ho Chi Minh City.
- 21 days: add the Mekong, Da Lat or Phu Quoc.
Each region needs a minimum of 3 to 4 days. Trying to cover the whole country in under 10 days means spending most of it in transit.
Map mistakes to avoid
Assuming Hanoi is mid-country. Treating Thailand as a neighbor. Booking Hanoi to Ho Chi Minh City by bus or train on a short trip. Confusing the several Monkey Islands. Using pre-2025 province names for transport searches. Ignoring the central typhoon season. Fix these six and most itinerary problems disappear before you book anything.
FAQ
