After our guide to combining Laos and Cambodia, here is the other question travelers ask us most: can you visit Laos and Vietnam in one trip? You certainly can – and it is one of the most rewarding contrasts in Southeast Asia. On one side, the slow rhythm of the Mekong; on the other, the energy of Vietnam’s cities and the limestone seascape of Halong Bay – just over an hour’s flight apart. August to October is when most dry-season departures are planned, so now is the time to get the route, the borders and the season right.

Why combine Laos and Vietnam?

Because the two countries could hardly be more different, and that is exactly what makes the trip feel complete. Laos moves slowly: monks collecting alms at dawn in Luang Prabang, villages along the Nam Ou river, sunsets over the Mekong. Vietnam moves fast: Hanoi’s Old Quarter, a bowl of pho eaten on a plastic stool, junks gliding between the karst pillars of Halong Bay. You will pass more scooters in ten minutes in Hanoi than in a whole week in Laos.

The logistics are refreshingly simple: direct flights link Luang Prabang and Hanoi in about 1 hour 10 minutes, operated by Lao Airlines and Vietnam Airlines on most days of the week, and Hanoi is also connected to Vientiane nonstop. No day is lost in transit – you can watch the sun rise over the Mekong and eat dinner in Hanoi’s Old Quarter the same evening.

Visas: simpler than you might think

Vietnam has made things easy for many visitors. Citizens of France, the United Kingdom, Germany, Italy, Spain and several other European countries currently enter Vietnam visa-free for stays of up to 45 days, a policy in force until March 2028. The only requirement is a passport valid for at least six months after arrival. Travelers from the United States, Canada, Australia and most other countries apply for Vietnam’s 90-day e-visa on the official portal evisa.gov.vn (25 USD single entry, 50 USD multiple entry). Avoid look-alike agency websites that charge double for the same document.

For Laos, the official e-visa is issued at laoevisa.gov.la – but note that it is only accepted at certain entry points: the airports of Vientiane, Luang Prabang and Pakse, Friendship Bridges I, II and IV, Boten, and the Laos-China railway stations. It is not valid at the land borders between Laos and Vietnam. That one detail should decide the direction of your trip.

Which direction should you travel?

Our advice as a local agency: start in Laos, finish in Vietnam. Fly into Laos with your e-visa, travel down the country at your own pace, then cross into Vietnam – by air or overland – where many nationalities need no visa at all. Nothing can go wrong at the border.

The reverse works too, but needs more care: entering Laos overland from Vietnam means obtaining a Lao visa on arrival, which is issued at the main international checkpoints – but not at all of them. Have your crossing point confirmed before you set off, or simply ask us: checking borders is part of our job.

Three itineraries that work

The essentials in 12 to 15 days

The classic route: three nights in Luang Prabang (the alms-giving ceremony, Kuang Si waterfalls, Pak Ou caves), on to Vang Vieng and its karst scenery – now just an hour away by train – then easy-going Vientiane. Fly to Hanoi, spend two days in the Old Quarter, then sleep aboard a junk in Halong Bay. This is the spirit of our Indochina UNESCO tour, which links the World Heritage sites of both countries in 13 days.

Three weeks: add central Vietnam

With one more week, the trip changes scale: after Hanoi and Halong, head south to Hue, the former imperial capital, and Hoi An, the lantern-lit trading town on the UNESCO list. On the Lao side, three weeks also leave room for the 4000 Islands or the Bolaven Plateau before crossing over – the Lao Bao border gate, near Savannakhet, leads straight to Hue.

The northern route, for slow travelers

Our favorite, far from the crowds: from Luang Prabang, head up to Nong Khiaw and its cliffs, then continue by boat along the Nam Ou river to Muang Khua. From there, the Tay Trang border gate opens onto Dien Bien Phu, then the terraced rice fields of northern Vietnam and Hanoi. Very few travelers make this crossing – none of them forget it. For a month or more, our Grand tour of the Indochinese kingdoms covers the whole peninsula.

Borders and transport: what to know

Flying remains the easiest option: Luang Prabang to Hanoi nonstop, or Vientiane to Hanoi. Overland links exist but are earned: the Vientiane-Hanoi bus via the Cau Treo border gate runs for a full day and night – an adventure in itself, best left to hardened travelers.

For overland crossings, eight international border gates between the two countries accept Vietnam’s e-visa, from north to south: Tay Trang (for Dien Bien Phu), Na Meo, Nam Can, Cau Treo, Cha Lo, La Lay, Lao Bao (for Hue) and Bo Y. Formalities are slower than at the airports: allow extra time, carry small banknotes, and pack some patience.

When to go?

November to March is the sweet spot for both countries: dry season in Laos, clear skies and gentle heat. Two nuances are worth knowing. Northern Vietnam is cool and often misty from December to February – bring a fleece for Halong Bay and the mountains. Central Vietnam (Hue, Hoi An) has its typhoon season from September to early November, so it is best visited from December onwards.

Frequently asked questions

Do I need a visa for a Laos and Vietnam trip?

For Vietnam, citizens of France, the UK, Germany, Italy, Spain and several other countries enter visa-free for up to 45 days; most other nationalities use the official 90-day e-visa (evisa.gov.vn). For Laos, apply for the e-visa at laoevisa.gov.la and enter through an approved port such as Vientiane or Luang Prabang airport. We double-check the rules for every traveler before departure.

How many days do I need?

Twelve days is a sensible minimum. Fifteen days makes a well-balanced trip, and three weeks lets you add central Vietnam or southern Laos.

Can I cross the border overland?

Yes – eight international border gates accept Vietnam’s e-visa. Traveling from Laos into Vietnam is the simple direction. In the other direction, make sure your chosen checkpoint issues the Lao visa on arrival – not all of them do.
