Vietnam vs Thailand: Which One for Your First Trip

Vietnam vs Thailand: Route Shape and Travel Time

Look at the two maps before anything else. The shape decides the trip.

Train SE1 leaves Hanoi at 20:50 and reaches Saigon at 05:45 two mornings later. The timetable on Seat61 puts the distance at 1,726km, every one of them inside a single long, thin country. Thailand's nearest equivalent, Special Express 9, pulls out of Bangkok at 18:40 and is in Chiang Mai at 07:15, in time for breakfast. One country is a line you travel along. The other is a wheel with Bangkok at the hub, and most of this decision follows from that difference in shape.

The crowd is shifting while you decide. Vietnam counted more than 17.7 million foreign visitors in the first nine months of 2026, up 14.5% on a year earlier, while Thailand's tourism ministry had 21.28 million by 5 September, down 3.12%. Thailand remains the bigger, smoother operation. Vietnam is the one gaining. This Vietnam vs Thailand comparison takes the choice factor by factor, food first, and ends with the one I'd book for a first trip.

Look at the two maps before anything else. Vietnam runs north to south in a strip so narrow that its main railway is, in effect, the itinerary: Hanoi at the top, Huế and Da Nang in the middle, Ho Chi Minh City at the bottom, 1,726km apart by rail. Nobody sensible returns the way they came. You fly into one end and out of the other, and every stop is a commitment, because doubling back costs a day. The reward is that the country changes as you go. Our Vietnam food guide is built on the same idea: the cooking shifts every 500km or so, and the weather shifts with it.

Thailand works the other way. Almost everything radiates from Bangkok: the sleeper north to Chiang Mai, the old capital of Ayutthaya a local train ride away, the flights south to the islands. You can land, find your feet for three days, pick one direction and still be back for the flight home, which is why ten days in Thailand feels like a holiday and ten days in Vietnam can feel like a relay.

Shape decides the calendar too. British government travel advice splits Vietnam's rainy season by region, north and south from June to September and the centre from October to December, against one season for most of Thailand, May to October, with Ko Samui as the exception. So choose the month first; our month-by-month guide to Southeast Asia helps.

Vietnam: one trunk line, end to end

Food: Vietnam, Narrowly, and Mostly at Breakfast

Both kitchens run on rice, fish sauce and herbs. One of them peaks before nine.

Both kitchens are built on rice, fish sauce and fresh herbs, and after that they part company. Thai cooking leans on chilli, lime and palm sugar, on pounded curry pastes, and on regional styles from the grilled meats of Isan to the fierce curries of the south. Vietnamese cooking is quieter: clear broths, rice paper, a plate of raw herbs on every table.

In Hanoi's Old Quarter this month, the state news agency VNA met a 62-year-old visitor from Manila who ate phở every morning of the trip, and listed bún chả, grilled pork with rice noodles, alongside the season's cốm, young green rice from Vòng village. Bangkok's range shows in a guidebook count: Michelin's Bib Gourmand list has 32 addresses in the city, three of them filed under street food. Our Bangkok food guide walks Yaowarat, the Chinatown strip, stall by stall.

Eat on each country's clock. Vietnam is a morning country, and our Hanoi food guide sets out when its kitchens close. Bangkok gets going after dark. On price, Nomadic Matt's Vietnam page puts a street dish at 20,000₫ (about 77 US cents) and his Thailand page at 30 to 100 baht ($0.90 to $3). I'd give Vietnam the edge on breakfast and value, Thailand on variety after 8pm.

Neither country is easy for strict vegetarians, since fish sauce gets into almost everything. Thai food is also hotter than most first-timers expect. Vietnam's catch is the reverse: its best shops sell one dish and shut once the pot is empty.

Cost: Vietnam, at Roughly Half

The gap holds line by line, from the dorm bed up.

The cleanest like-for-like figures are Nomadic Matt's suggested daily budgets, because one writer applies one method to both countries. His Thailand page, updated in September 2026, has a backpacker at 1,750 baht a day (about $52) and a mid-range traveller at 3,100 baht ($92). For Vietnam he gives 600,000₫ ($23) and 1,125,000₫ ($43).

The gap holds line by line. A dorm bed runs 275 to 550 baht ($8 to $16) in Thailand against about 100,000₫ ($4) in Vietnam, and a beer is 60 to 120 baht against 20,000₫ to 35,000₫, or $1.80 to $3.60 against roughly a dollar. The surprise is the railway. Seat61 lists a soft-sleeper berth from Hanoi to Da Nang at 1,294,000₫, about $50, while a second-class lower berth on the newest Bangkok to Chiang Mai sleeper was 1,038 baht ($31) at the last fares it recorded.

For planning, I'd carry $30 to $45 a day in Vietnam and $55 to $95 in Thailand before flights, and budget the Thai islands at the top of that range. The rail gap matters less than it looks, because a first trip to Vietnam needs only one or two train legs. Convert at about 33.5 baht or 26,000₫ to the US dollar, the rates in October 2026.

The Vietnam figures date from March 2025 and the Thai rail fares from 2023, so read both as floors. Thailand may also get dearer at the border: VnExpress International reported on 8 October that two proposed levies could take charges on foreign visitors to about $77.

Paperwork: Thailand Has Just Got Harder

The 60-day exemption ended on 15 September 2026.

Thailand's 60-day visa exemption ended on 15 September 2026. The Tourism Authority of Thailand now lists 60 countries and territories, the UK, US, Canada and Australia among them, whose citizens get 30 days for tourism. Vietnam gives British passport holders 45 days without a visa, and offers every nationality a 90-day, multiple-entry e-visa.

Thailand asks for more at the desk than its easy-going reputation suggests. Every foreign arrival must register a Thailand Digital Arrival Card online in the three days before landing, and the British government's entry advice says officers may ask for 10,000 baht (about $300) in funds and proof of onward travel, adding that British nationals have been turned away without them. Vietnam's process is quieter. Its digital arrival card is encouraged, and only at Ho Chi Minh City's Tan Son Nhat airport, since 15 April 2026.

Check your passport first: both countries want six months' validity beyond arrival. Americans and Australians are absent from the Vietnamese tourism board's exemption list, so apply for the e-visa on the government portal before you fly, and name the right entry and exit points, because the visa is tied to them. For Thailand, fill in the arrival card at home and keep the confirmation on your phone.

Overstaying in Thailand costs 500 baht a day, up to 20,000 baht, with detention and a re-entry ban possible. In Vietnam, read the stamp before you leave the airport, because immigration will not correct the date afterwards. Thai entries by land are capped at two a year.

The Thai rule is weeks old and plenty of websites still quote 60 days. For a stay of five or six weeks, apply for a tourist visa before you travel, or ask Thai immigration about an extension of up to 30 days once you are inside the country. Approval is at their discretion.

Getting Around: Thailand Is Easier, Vietnam Is Better by Rail

One trunk railway against a network that radiates.

Vietnam has one trunk railway and a queue of sleeper trains running along it daily: SE1, SE3, SE5 and their northbound twins. Thailand's long-distance trains start from Krung Thep Aphiwat Central, the Bangkok terminal that took over these services from Hualamphong in January 2023, and fan out north, north-east and south.

Mark Smith, who runs Seat61, calls Special Express 9 to Chiang Mai 'the best train to take', for its newer Chinese-built sleeping cars and its restaurant car. That car has sold only alcohol-free beer since a 2014 ban, so plan your disappointments in advance. Vietnam's carriages he describes as worn, even the newer ones, though berths come with a pillow, sheet and duvet and there is free hot water. His highest praise goes to the stretch between Huế and Da Nang, where the line runs beside the sea and climbs the Hải Vân Pass.

In Vietnam I'd skip the 33-hour through run and ride two legs: Hanoi to Huế overnight, 1,218,000₫ (about $47) for a soft-sleeper lower berth, then Huế to Da Nang in daylight for 265,000₫ ($10). Booking opens about 60 days out. Thai sleepers go on sale up to six months ahead on the State Railway's own site. Fly the longer gaps in both countries.

Flood season reaches the rails: on 17 September VNA reported the Hanoi to Ho Chi Minh City line under a metre of water between Bỉm Sơn and Đò Lèn, with passengers bussed around the gap. And leave the rental scooter alone. The State Department says American licences are not valid in Vietnam at all.

Seat61 warns that Vietnam Railways' own website can reject foreign cards. If yours bounces, book the same trains through 12Go or Baolau, which show live availability, or buy at the station. Do not leave it to the station in the week of Tết, when seats sell out.

Temples or Scenery: Thailand Has the Monuments

Thailand’s headline sights are built. Vietnam’s are not.

Thailand's headline sights are built things. Ayutthaya, founded around 1350 as the second Siamese capital and razed by a Burmese army in 1767, survives as 289 hectares of prang towers and monastery ruins on UNESCO's list. Vietnam's are shaped by water and trade: the limestone bay at Hạ Long, and Hội An, a port that worked from the 15th to the 19th century.

UNESCO calls Hội An 'an exceptionally well-preserved example of a small-scale trading port' and counts 1,107 timber-frame buildings inside it. Hạ Long is no secret: its province, Quảng Ninh, drew about 18.8 million visitors in nine months of 2026, VNA reports, 4.21 million of them from abroad. Bangkok's old city came through the September floods open, with the Tourism Authority listing the Grand Palace, Wat Pho and Wat Arun as operating, and on 6 November 52 gilded barges pass the palace on the way to Wat Arun in the Royal Barge Procession.

Do Ayutthaya as a day trip: Seat61 notes that local trains run from Hualamphong with no reservation, so you buy a ticket and board. Our list of things to do in Bangkok covers the capital itself. For Hạ Long, British travel advice is to check a boat's registration and safety record before an overnight cruise. My pick for monuments is Thailand; for a view from a deck, Vietnam.

Hội An sits in the central flood belt, so October and November are a gamble. On the Thai side, the temples along the Cambodian border are closed, and the UK advises against all but essential travel within 20km of that frontier.

Weather and Beaches: Winter Favours Thailand

One main rainy season against a country long enough to have three.

Thailand keeps one main rainy season, May to October, and one exception: British travel advice puts the wet months for Ko Samui and the south-east at November to March. Vietnam divides by region. The north and south are wettest from June to September, the centre from October to December, and tropical storms can hit the eastern coast between May and November.

This autumn supplied the evidence. Bangkok took about 330mm of rain in 48 hours in late September and all 50 districts were declared disaster areas; by the 30th, Time Out Bangkok's Aydan Stuart wrote that the 'worst flooding is receding', with 28 of 45 flagged zones clear and the BTS, the MRT and both airports running. Northern Vietnam flooded a fortnight earlier, when VNA counted 16,310 homes under water. On 9 October, VnExpress reported that Da Nang had suspended sightseeing on the Sơn Trà peninsula as the monsoon arrived.

From November to February I'd pick Thailand: Chiang Mai is dry and the Andaman coast is in season. Vietnam in those months means Hanoi in a jacket, Saigon and the island of Phú Quốc in sunshine, and the middle in the rain. From March to August the argument flips, and Da Nang's beaches, up 68% in Skyscanner's 2027 trend data, are the reason. Our pick of Southeast Asia's best islands goes coast by coast.

Seasons are a tendency now. The same advice warns that Thai weather is getting harder to predict and that heavy rain can fall anywhere. Buy insurance that covers disruption, and spend the last night of any trip near the airport.

Ko Samui in December. The Gulf island runs on the opposite calendar to almost everywhere else in Thailand, and booking it for Christmas on reputation alone is the classic first-timer's mistake. If you want sand in midwinter, look to the Andaman side instead.

A quiet beach on a bright day — which month decides which country.

The Rules That Catch First-Timers Out

Vapes first, then the alcohol hours.

Vapes are the commonest way to get into trouble. In Thailand, possessing one is illegal, with fines that UK government advice puts at 5,000 to 30,000 baht ($150 to $900), and its wording is blunt: 'There are no exceptions for tourists or for personal use.' Vietnam bans them too; they cannot be bought there or brought in. Cannabis in Thailand is restricted to medical use and needs a Thai prescription.

Thai shops may not sell alcohol between midnight and 11am, with exceptions for licensed hotels, airport terminals and entertainment venues. In Vietnam, the equivalent page warns that police test for drugs at raids and that a positive result can bring charges even if the drug was taken before arrival. Both countries have recorded deaths from methanol in alcoholic drinks, so I'd keep to sealed beer. In Thailand, criticising the monarchy is a crime that carries a long sentence. Save the opinions for the flight home.

Two Weeks in Each: The First-Trip Route

One for each country, booked the way I would book it.

Thailand, 14 days: four nights in Bangkok, with one evening in Yaowarat and one day out at Ayutthaya; the sleeper north; four nights in Chiang Mai; then a flight south for five nights on whichever coast is in season, and a last night back in Bangkok.

Vietnam, 14 days, north to south: four nights in Hanoi, eating in the Old Quarter each morning, with a day or a night on Hạ Long Bay; the overnight train to Huế for two nights; the daylight ride over the Hải Vân Pass to Da Nang, and four nights split between its beach and Hội An; then a flight to Ho Chi Minh City for the last three. With a third week I'd give it to Vietnam, where the line has more stops than a fortnight can hold.

The Two, Factor by Factor

Food, cost, paperwork, rail, sights — and my pick on each.

Dollar figures convert at about 33.5 baht and 26,000₫ to US$1, the rates in October 2026. On the cards, ₫ and ฿ mean a street meal for under about $3; ₫₫ and ฿฿ mean a sleeper berth of roughly $28 to $70. Budgets are Nomadic Matt's: Thailand updated September 2026, Vietnam March 2025.

11SOUTHEAST ASIA

Timing, Money, Booking and Time

Open-jaw into Hanoi, and Thai sleepers six months ahead.

When to go: Thailand from November to February. Vietnam's central coast from March to August, and its two ends during the northern winter. Tết falls on 6 February 2027, and many family businesses in Vietnam close around it. Songkran, the Thai new year water festival, runs from 13 to 15 April.

Getting there and around: Book Vietnam open-jaw, into Hanoi and out of Ho Chi Minh City or the reverse. Thailand works as a simple return to Bangkok. In Vietnamese cities, UK advice is to book Grab or Xanh SM through the app and check that car and driver match it.

Money: Work on about 33.5 baht or 26,000₫ to the US dollar. Carry small notes in both countries for street food and local trains. As of 11 October 2026, the British entry advice for Thailand lists no visitor levy; look again before you fly.

Booking: Thai sleepers sell up to six months ahead and Vietnamese ones about 60 days. Register the Thailand Digital Arrival Card at tdac.immigration.go.th, and apply for Vietnam's e-visa only on the government's own portal.

How long: Ten days is enough for Bangkok and one direction. Vietnam wants two weeks at the least, three if you can.

Safety: The US rates both countries Level 1, its lowest. Britain advises against all but essential travel within 20km of Thailand's border with Cambodia and to Pattani, Yala and Narathiwat in the far south; none of the routes above goes near either. After the September floods, the Tourism Authority's 29 September update had Bangkok's main visitor areas, both airports and the rail network operating. In Vietnamese cities, carry your bag on the side away from traffic, because motorbike bag-snatching is common.

The Bottom Line

Book Thailand for this winter, and Vietnam for the spring.

Thailand is the better first trip and Vietnam is the better second one. That is no slight on Vietnam. A first visit to this part of the world goes well when the logistics stay out of the way, and Thailand's hub, its sleeper trains and its dry winter manage that better than a 1,726km line with a different forecast at each end. Vietnam is where I'd send anyone who plans a trip around meals, has three weeks and likes the idea of never retracing a step. It is cheaper, it is gaining visitors while Thailand loses them, and it starts serving breakfast earlier.

Book Thailand for this winter, and Vietnam for the spring after.
