Vietnam vs Thailand: Which Is Cheaper and Better in 2027?

Vietnam vs Thailand, in one line: Thailand is the easier holiday and the better beach country, and Vietnam is a little cheaper and far stronger for caves and mountains. A bowl of street noodles costs about the same in both, $1.50 to $2.50. The gaps are beer, rooms, the shape of the route and a Thai visa rule that halved visa-free stays to 30 days on 15 September 2026.

We run cave trips in Phong Nha, so we are not neutral about caves. We say so where it matters, and we say plainly where Thailand is the better choice. Prices below were checked in October 2026 and converted at 26,000 dong and 32.5 baht to the US dollar.

Vietnam vs Thailand at a glance

Which is cheaper, Vietnam or Thailand?

Vietnam, but by less than people expect. The street food price is close to identical. What separates the two countries is drink and accommodation, and those add up over two weeks.

The Vietnam figures come from Vietnam Airlines' cost guide and 2026 pho prices; the Thai ones from a Thailand budget guide updated July 2026. They are planning ranges, not receipts. The pattern still holds on the ground: a beer drinker staying in private rooms saves something like $10 to $20 a day in Vietnam, and someone eating street food in a dorm saves very little.

Two things wipe out the saving. Flights into Bangkok are often cheaper than into Hanoi or Ho Chi Minh City from Europe and Australia, so price your own route before deciding anything. And Vietnam is long and thin, which means more domestic flights. Our Vietnam ultra low budget guide shows what a week really costs once transport is in.

Beaches: Vietnam vs Thailand

Thailand wins, and it is not close if the beach is the whole point.

The reason is geography. Thailand has two island coasts with opposite weather. The Andaman side, meaning Phuket, Krabi and Koh Phi Phi, is dry from roughly November to April and wet from May to October. The Gulf side, meaning Koh Samui, Koh Phangan and Koh Tao, flips it: drier in the middle of the year and wettest from October to December, with November the soggiest month on Samui. Whenever you travel, one coast is usually working. Inter-island ferries run 200 to 600 baht, so hopping is cheap.

Vietnam has over 3,000 km of coast and good beaches on it, but they behave differently. Da Nang has a long city beach where red flags are common from October to February. Phu Quoc is the dry-season island, with about 6 rain days in December against 19 in Da Nang. If you want a beach week in Vietnam, our Phu Quoc guide is where we would start.

Which country is dry when

This is the table we wish someone had shown us before our first trip. It is the main reason a Vietnam vs Thailand decision changes by month.

So for Vietnam or Thailand in December: Thailand's Andaman coast is the safer beach bet. Vietnam in December works if you want Hanoi at 21 degrees and the south, and accept rain on about 19 days in Da Nang and Hoi An. For the long version, see the best time to visit Vietnam by region.

Caves and adventure: where Vietnam wins

Thailand has caves. Tham Lod in Mae Hong Son is visited by bamboo raft, and Nam Talu in Khao Sok has an underground river you wade and swim through, usually closed through the rainy season. These are a few hours underground and then back to the hotel.

Phong Nha is a different scale of thing. It sits in Phong Nha Ke Bang, a World Heritage park full of river caves, and the trips go for days. Our hardest, the Kong Collapse expedition, is 5 days and 4 nights for VND 35,000,000 (about $1,346). Day 1 is a health check and abseil training; on day 3 you go 100 m down the collapse in three stages of 30, 20 and 50 m, then camp at the bottom. Day 4 adds a swim in Tiger Cave and a 10 m abseil into Pygmy Cave, where you sleep at the entrance. It takes 10 people at most, the minimum age is 16, and it leaves on Tuesdays and Fridays. Before departure there is a health statement and a check by the Jungle Boss medical team, and the release form is signed on day 2.

The honest limit: this is graded Extremely Strenuous, and people who are fit from the gym still find wet limestone hard. Do a one or two day trip first if you have never camped in a jungle. And to be clear, we do not run Son Doong or Hang En; those are sold by a different operator. The Kong Collapse adventure tour guide walks through the full five days.

Thailand's version of adventure is mostly at sea: sea kayaking around Krabi's karsts, diving off Koh Tao, rock climbing at Railay. If the adventure you want is under water, Thailand is the better country. Vietnam's edge is on land and underground, plus the northern mountains around Sapa and Ha Giang. Our things to do in Phong Nha lists the cave trips that fit an ordinary itinerary.

Food: Thailand vs Vietnam

Call it a draw and choose by what you like eating.

Thai food is built on heat, sugar, sour and fish sauce in one mouthful: som tam, green curry, khao soi in Chiang Mai. Vietnamese food leans on broth and fresh herbs, and changes a lot by region. Pho is a Hanoi breakfast. Bun bo Hue is spicier and comes from the old capital. The south eats sweeter. Coffee is its own reason to go, at 20,000 to 35,000 dong a cup in an ordinary cafe, and the strong drip coffee with condensed milk is nothing like a Bangkok iced latte.

Vegetarians have a slightly easier time in Thailand, where "jay" vegan stalls are common. In both countries fish sauce goes into dishes that look meat free. Our guide to Vietnamese food lists what to order where.

Getting around, and doing both in one trip

Thailand is easier to move through. Bangkok has the BTS Skytrain at 17 to 65 baht a ride, and from there a short flight puts you on almost any island. A ten day trip can be Bangkok plus one beach and feel unhurried.

Vietnam punishes the classic mistake, which is trying to see Hanoi, Halong Bay, Phong Nha, Hue, Hoi An and Ho Chi Minh City in ten days. The rail line from Hanoi to Ho Chi Minh City is 1,726 km. A sleeper bus from Hanoi to Phong Nha takes 10 to 12 hours for $12 to $18; flying to Dong Hoi takes about 1.5 hours for $50 to $100, then 45 minutes by road. Start with how many days you need in Vietnam and cut stops before you book anything. If you do want the whole length, a 13-day Hanoi to Ho Chi Minh City tour is the pace it actually needs.

Can you do both? Yes. Bangkok to Hanoi is a 1.5 to 2 hour flight, so two weeks split as Bangkok and an island, then Hanoi and Phong Nha, works. Under ten days, pick one country. Two sets of airports eat the time you saved.

Visas in 2026: the rules just changed

Most comparison pages still say Thailand gives 60 days visa free. That ended. From 15 September 2026, per the Thai government's notice, the 60 day scheme is revoked and a 30 day tourism exemption covers 60 countries and territories, including the US, UK, Australia, Canada and Germany. Visa on arrival shrinks to three countries. If you come in overland on the exemption, you get two land entries per calendar year.

Vietnam works the other way round. UK, German, French, Italian, Spanish, Japanese and Korean passports, among others, get 45 days without a visa. Americans, Australians and Canadians need the e-visa from the official portal: US$25 single entry or US$50 multiple, valid up to 90 days. Phu Quoc allows 30 days visa free if you fly straight there. Lookalike agency sites charge $40 to $90 on top, so check the address bar. More in our Vietnam visa guide.

Crowds and nightlife: Vietnam vs Thailand

Thailand took 32,974,321 foreign tourists in 2025. Vietnam took about 21.2 million, a record. You feel the gap on the islands and in Chiang Mai, and you feel it in the service: Thailand's tourist trade has more English, more booking desks and more polish. The flip side is that the main Thai circuit feels built for visitors.

For nightlife Thailand wins outright. Khao San Road and Phuket's Bangla Road run until late, and the Full Moon Party on Koh Phangan pulls thousands every month. Vietnam's nights are smaller: plastic stools and bia hoi on Hanoi's Ta Hien Street, the rooftop bars of Ho Chi Minh City, a few beach bars in Da Nang. Fun, cheap, and in bed by one.

Traffic is the bigger day to day risk in Vietnam, and motorbike rental without a valid licence usually voids travel insurance in both countries. The Vietnam safety guide covers scams and road rules.

Vietnam or Thailand with kids

For a first family trip with small children, Thailand. One resort, short transfers, kids' clubs, and the beach is right there.

Vietnam rewards families with children of 9 and up who like getting wet and muddy. Our Elephant Cave and Ma Da Valley day trip costs VND 1,950,000 (about $75), takes children from 9, picks up around 08:00 and includes a 600 m swim through a water cave with life jackets. The Phong Nha with kids guide covers which trips suit which ages.
