The Indochina Triangle
The classic overland loop through northern Laos and northern Vietnam - Luang Prabang's temples, the Vang Vieng karsts and Vientiane, then across to Hanoi's Old Quarter and the limestone islands of Halong Bay.
9–16 days · Point-to-point
When to go
- VisaLaos + Vietnam e-visas — apply for both a week or two ahead; the Laos border also does visa-on-arrival but the Nam Phao/Cau Treo land crossing is smoother with paperwork done
- WeatherNorthern Vietnam winter chill (Dec - Feb) — Hanoi and the highlands turn genuinely cold and grey - pack a warm layer; Halong cruises can be misty
- WeatherSE-Asia monsoon + slash-and-burn haze (May - Sep rain; Mar - Apr haze) — avoid - Laos rivers flood and the northern-Laos dry-season crop burning blankets the region in smoke
The Indochina Triangle is the overland trip most first-timers to the region dream up: start soft in Laos, where Luang Prabang's temples and the Vang Vieng karsts set an unhurried pace, then cross into the sensory overload of northern Vietnam - Hanoi's Old Quarter and the limestone seascape of Halong Bay. It's really two very different countries stitched together by one crossing, which is where the pacing matters most. Give it 12 days; with 15 you can fold in Sapa's terraces and Ninh Binh's inland karst.

Luang Prabang
2 nightsThe gentle start: a UNESCO peninsula of gilded wats and French-colonial shophouses, the dawn alms procession, Kuang Si waterfalls and the best night market of the trip.
Skip / overrated: The 5am alms-giving is a genuine ritual, not a photo op - watch respectfully from a distance and skip it entirely rather than buying rice from touts to join in.
View Luang Prabang guide→Getting there· ~112 kmBusRecommendedMinivans and VIP buses do the scenic mountain run in ~4-5h; the road twists relentlessly, so take motion-sickness pills.
Book: 12Go / guesthouse — the cheap crowded minivan is a white-knuckle switchback ride - pay up for a bigger VIP bus if you're prone to carsickness
Book busesCarPrivate car with driver, ~4h and far more comfortable on the mountain curves; splits well between two or more people.

Vang Vieng
2 nightsKarst-cliff country reinvented as an outdoorsy stop - lagoons, caves, kayaking and hot-air balloons over the Nam Song, with the old party-tubing reputation now mostly tamed.
Skip / overrated: The remaining 'happy' menus and river-bar tubing circus are a hangover from the reckless 2010s; the scenery is the reason to come, not the buckets.
View Vang Vieng guide→Getting there· ~107 kmBusRecommendedFrequent minivans and the express take ~3.5-4h on the improving highway south to the capital.
Book: 12Go / guesthouse — the shared minivan waits until it's full before leaving - book the fixed-departure express if you have an onward connection
Book busesCarPrivate transfer ~3h with the freedom to stop at Vang Vieng viewpoints on the way out.

Vientiane
2 nightsAsia's sleepiest capital and the logical jumping-off point for the crossing into Vietnam - Pha That Luang, riverside sunsets and a last easy dose of Lao coffee.
Skip / overrated: Vientiane is a half-day of sights stretched over a relaxed overnight; don't expect big-city buzz - its charm is the calm before Hanoi.
View Vientiane guide→Getting there· ~477 kmBorder crossingFlightRecommendedThe sane way to cross: a short direct hop Vientiane→Hanoi that turns a punishing overland day into an hour in the air.
Book: airline / Google Flights — book direct - some fares route via Bangkok and double the day; check the leg is nonstop
BusThe classic overland border crossing via the Nam Phao - Cau Treo gate - a long, rough ~20-24h sleeper-bus haul that backpackers still do for the adventure and the visa stamp.
Book: 12Go / bus station — the through-buses are notorious for overcharging at the border and cramped conditions - carry small USD for the crossing fees, keep valuables on you, and expect delays
Book buses - 4
Hanoi
3 nightsThe trip's high-energy heart: the tangled Old Quarter, egg coffee and bun cha, the Temple of Literature and a chaotic, brilliant street-food scene.
Skip / overrated: Skip the 'traditional' water-puppet show if you're short on time (charming but touristy) - the Old Quarter street life and a food walk are the real Hanoi.
View Hanoi guide→Getting there· ~140 kmBusRecommendedAlmost everyone books this as a cruise package that includes the ~2.5-3h shuttle transfer from Hanoi to the pier and back.
Book: cruise operator / 12Go — the transfer is bundled into reputable cruise fares - book the boat, not a separate bus, and confirm which harbour (Halong vs Lan Ha) it departs from
Book busesCarPrivate car ~2.5h if you want to arrive independently; the new expressway has cut the drive considerably.

Halong Bay
2 nightsThe postcard finale: an overnight cruise among thousands of limestone islands, sea caves and quiet kayaking coves - best done as a 2-day/1-night sailing from Hanoi.
Skip / overrated: The main Halong tourist harbour is a cruise-boat factory; pay a little more for a smaller boat routing through Lan Ha / Bai Tu Long Bay to escape the flotilla.

What to skip
Don't try to bolt on central Vietnam (Hue, Hoi An, Danang) to this loop - it turns a relaxed northern circuit into a country-length dash. Save the centre for a dedicated Vietnam trip. And resist doing the Vientiane - Hanoi crossing by overnight bus unless the journey itself is the point; the short flight buys back a full day.
Practical tips
Do both e-visas before you fly, carry small US dollars for the land border and Lao markets, and treat the Laos legs as scenic and slow - the mountain roads are curvy. Book your Halong cruise on reputation, not price, and confirm which harbour it sails from.

Common questions
Which direction should I travel - Laos to Vietnam or the reverse?
Laos first is the gentler build: you ease in with Luang Prabang and Vang Vieng, then hit Hanoi's intensity when you're acclimatised. Either works, but most travellers fly into Luang Prabang and out of Hanoi.
Should I fly or take the bus from Vientiane to Hanoi?
Fly if you value your time - the direct hop is about an hour. The overland Nam Phao - Cau Treo border bus is a ~20-hour adventure that backpackers still do, but it eats a full day and is famously cramped.
When is the best time to go?
November to March is the sweet spot - dry and cooler. Avoid the May - September monsoon and the March - April crop-burning haze in northern Laos, and pack a warm layer for a chilly Hanoi winter.
