There is a trip that nearly every long-haul traveller has either taken or thought about taking. It starts in Bangkok with a tuk-tuk ride from the airport into a wall of neon and street food. It ends three or four weeks later on a Bali beach with the kind of suntan that comes from sustained outdoor effort rather than a single afternoon. Between those two points it crosses five countries, four currencies, three different scripts, and a stretch of geography so dense with temples, jungles, beaches, and food that you finish it wondering how anywhere else on earth could ever feel like enough.
This is the Bangkok to Bali overland trip — what an older generation of travellers called the Banana Pancake Trail, and what every backpacker, sabbatical-taker, and slow-traveller from the last fifty years has been walking some version of. The infrastructure has improved. The countries have changed in ways large and small. But the trip itself has lost none of its grip. You can still do it for €30 a day if you want to. You can still cross a border on a sleeper bus and wake up in a different language. You can still order the same dish you had in Hanoi from a beach stall in Lombok and have it taste like a different food group.
There is one thing about the trip that has, until very recently, remained stubbornly difficult: staying connected.
The route, in one sentence
Thailand → Cambodia → Vietnam → Laos → Malaysia → Bali, Indonesia. Three weeks comfortable, four weeks ideal, two weeks if you fly the longer legs. Roughly 5,000 kilometres in total, almost all of it by bus, train, ferry, or short flight. The one unavoidable flight is the last one — Kuala Lumpur or Singapore to Bali — because the Java Sea has no land bridge and the old ferry routes no longer carry passengers. Everything else can be done on the ground if you want it that way.
You can run the route in either direction. Bangkok to Bali is the classic shape — north dry season to south wet season, Buddhist temples to Hindu ones, mainland to island. Bali to Bangkok works equally well and is sometimes cheaper to fly into. We will describe it southbound.
Why this trip, why now
Three things have made Southeast Asia overland travel measurably better in the last few years. The first is the highways. Vietnam’s Reunification Express still rolls the length of the country, but the parallel North–South Expressway has cut driving times in half. Thailand’s airport-rail networks have extended into the regions. Laos’s high-speed railway, opened in late 2021, has turned an eight-hour minibus crawl from Vientiane to Luang Prabang into a two-hour train ride. The route is now faster, cheaper, and dramatically more comfortable than it was in 2010.
The second is the food scene. Southeast Asian cooking has always been world-class. What has changed is the recognition. Street stalls in Bangkok, Hanoi, and George Town now appear on the same lists as Michelin restaurants in Paris and Tokyo. Restaurant cooking in the major cities has matured into a serious modern cuisine that respects tradition while pushing it. You can eat well at every meal, every day, for less than the price of a single dinner in most of Western Europe.
The third is connectivity. Every country on this route has built out 4G across its major cities and most of its rural areas. Indonesia has 5G in Bali, Jakarta, and Surabaya. Vietnam covers the entire 1,650-kilometre Reunification line with usable data. Cambodia has caught up faster than anyone predicted. The infrastructure is in place — what was missing, until very recently, was a single sensible way to use it across all six countries on one plan. That is finally solved, and we will come back to it.
Days 1–4 — Thailand, the soft launch
Most overland Southeast Asia trips begin in Thailand, and most Thailand visits begin in Bangkok, and most Bangkok visits begin with that universal first-night moment where you step out of an air-conditioned taxi into a wall of humid air, neon, motorbike exhaust, and the smell of grilling pork. It is the most sensory introduction to Asia of any city on the route, and it is worth two or three nights at the start of any trip to acclimatise before everything else.
The classic Bangkok arc covers the Grand Palace and Wat Pho on day one, the Chao Phraya river and Chinatown on day two, and a long evening eating your way through one of the night markets — Jodd Fairs Rama IX is the current favourite, with Or Tor Kor and the riverside markets as alternatives. The temples can be done in a morning. The food cannot be done in a lifetime.
From Bangkok the route splits. Some travellers head south to the islands — Koh Tao, Koh Phangan, Koh Samui — before turning back north to the Cambodian border. Others head straight northeast on the night train to Aranyaprathet, crossing into Cambodia after a day of temples. The fastest version skips the islands entirely and aims for Angkor by the end of day four. The slower version adds three or four nights in the Gulf of Thailand before doubling back. Both work. The islands are worth a return trip if you cannot fit them now.
Days 5–7 — Cambodia, the slowdown
The Thailand–Cambodia border at Poipet is the route’s first proper culture shift. Within thirty minutes of crossing, the highway is rougher, the villages are smaller, the children wave at every passing vehicle, and the language has shifted from Thai to Khmer — a different alphabet, a different rhythm, a different way of looking at strangers. Cambodia is poorer than its neighbours and the difference shows in the first hour. But it is also one of the warmest, most genuinely welcoming countries in Asia, and it is where the pace of the trip slows down for the first time.
Siem Reap is the obvious base. Two full days at Angkor — sunrise at Angkor Wat itself on the first morning, the temple ruins of Ta Prohm and Banteay Srei on the second, the smaller jungle-buried temples that the tour buses skip if you have a third — and you have seen the great ancient monument of mainland Southeast Asia, with crowds that have thinned dramatically since the post-pandemic recovery. Hire a tuk-tuk driver for two days; the rate is fixed, the driver knows the timings to dodge other tour groups, and you will eat lunch at restaurants that no Western guidebook ever found.
Phnom Penh is two days. The Royal Palace, the riverside, the Russian Market for souvenirs, and — unmissably — the Khoun Sokh and Choeung Ek memorial sites for the Khmer Rouge genocide. Heavy material; necessary. The country’s recent history shapes everything you see and meet, and walking through these sites in a respectful morning is what separates a tourist from a traveller. The evenings are for the riverside food scene, where Khmer cooking — milder than Thai, sweeter than Vietnamese, deeply seafood-led — has its best showcase.
Days 8–13 — Vietnam, the long S-curve
Vietnam is the longest stretch of the trip and probably the most memorable. The country is shaped like an S along the South China Sea, and the route runs end to end — either Ho Chi Minh City in the south up to Hanoi in the north, or the reverse. The classic shape is south-to-north, ending at the Halong Bay cruise; reverse it if you prefer to finish in the warmer, sunnier south.
Ho Chi Minh City — Saigon, to anyone over thirty — is the country’s commercial engine. Three nights minimum. The Cu Chi tunnels half-day tour for the historical context, the War Remnants Museum for the difficult half, the District 1 rooftop bars for the modern Vietnam. Eat phở for breakfast, bánh mì for lunch, and a proper sit-down dinner at one of the open-front family restaurants where the prices are in dong and the menus are written in chalk.
Then the Reunification Express. The train runs the length of the country in 35 hours, but no sensible traveller does it in one go. Break it into segments: Saigon to Da Nang for Hoi An (a UNESCO old town with its yellow walls and lantern-lit nights, two unmissable nights), Da Nang to Hue for the imperial citadel and the surrounding emperor tombs (one full day), and Hue to Hanoi on the overnight sleeper if you can stomach a hard berth, or by short flight if you cannot. Each segment delivers a different Vietnam.
Hanoi is two or three nights at the end. The Old Quarter’s 36 streets — each named after the craft once practised there, Silver Street, Silk Street, Tin Street — is one of the great urban walking experiences in Asia. Egg coffee at a balcony café on Hang Gai. Bún chả at the famous Obama spot, or any of the cleaner-looking ones around it. A water-puppet show, which sounds gimmicky and is actually astonishing. Then the day trip out to Halong Bay or the inland karst landscape of Ninh Binh — both spectacular, with Ninh Binh now arguably the better choice as Halong has become busier than its natural beauty deserves.
Days 14–17 — Laos, the great slow detour
Most rushed itineraries skip Laos. Almost everyone who skipped it regrets it later. The country is the quietest, slowest, gentlest stop on the entire route, and it is where the trip catches its breath before the loud finale in Indonesia.
The natural route is Hanoi to Vientiane (short flight, one hour) and then the high-speed railway north to Luang Prabang. The railway opened in late 2021 and changed everything. What used to be an eight-hour minibus death-crawl through the mountains is now a smooth two-hour train ride through the same mountains, with proper seats and air conditioning and a viewing window the size of a doorway. The mountains have not changed. The pain of seeing them has.
Luang Prabang itself is the prize. Two nights minimum, three is better. A UNESCO old town of French-colonial wooden shophouses, gilded Buddhist temples, and saffron-robed monks who walk the morning alms route at sunrise — visible to any traveller willing to be on the street at 6 a.m. and respectful enough to watch from a distance rather than intrude. The night market is small, calm, and entirely unlike Bangkok’s; the food stalls in the side alleys serve the best laap and grilled fish in the country. The Kuang Si waterfalls are a half-day excursion; the slow boat down the Mekong toward the Thai border is a full-day excursion that some travellers describe as the best single day of their entire trip.
If three weeks is your limit, this is the segment to be most flexible about. The trip works without Laos. It works better with it.
Days 18–20 — Malaysia, the bridge between continents
From Laos the route turns south. The fastest path is Vientiane back to Bangkok and an overnight train south to Malaysia. The slower path is a flight from Vientiane to Kuala Lumpur. Either way, Malaysia is the trip’s bridge — the last mainland country before the flight to Indonesia, and a country that quietly punches above its weight on every front that matters.
Kuala Lumpur is one or two nights. The Petronas Towers at dusk. Jalan Alor’s hawker stalls. The bookshops and cafés of Bangsar. Three meals in KL — Malay, Indian, and Chinese, each in its own neighbourhood — will reset your expectations of what Southeast Asian food can be in a single urban geography.
If time permits, the detour to George Town in Penang is the route’s best last-minute decision. A British-colonial old town turned UNESCO World Heritage city, with the best street art in Southeast Asia, the best laksa on the planet, and a hawker scene that runs from 6 a.m. to 2 a.m. Two nights in George Town is enough to understand why so many travellers tag it as their favourite stop of the entire trip.
Days 21–24 — Bali and Indonesia, the long exhale
The final flight, Kuala Lumpur to Denpasar, lands you in Indonesia — and on Bali, the closing chapter that every Southeast Asia trip seems to converge toward. Three or four nights here. Avoid Kuta unless you are very specifically there for the surf. Ubud for two nights in the inland rice-terrace landscape, with morning yoga, afternoon walks through the Tegallalang terraces, and dinner at the warungs where the kakek and the nenek — the grandfathers and grandmothers — still cook the babi guling and the bebek betutu the way they have for fifty years. Then one or two nights on the coast — Canggu if you want surf and beach clubs, Amed if you want quiet diving on the east, Uluwatu if you want sunset cliffs and the famous Kecak fire dance.
Bali is where the trip pays off. After three weeks of moving, eating, packing, and unpacking, you arrive at a place that asks you to slow down and stay. The Hindu culture is a complete reset from the Buddhist countries to the north — temple offerings on every doorstep at sunrise, gamelan music drifting from rehearsals in the village halls, ceremonies that block the road for half an hour and which you are welcome to watch. The food is different again. The light is different. The pace is different.
For travellers with an extra week, the Indonesian archipelago opens further. Lombok and the Gili Islands for diving and snorkelling. Java for Borobudur and Yogyakarta. Komodo and Flores for the dragons and the pink-sand beaches. The country has 17,000 islands, and Bali is the easiest one to start with — but for many travellers, the moment of realising that Indonesia goes far beyond Bali is the moment a single trip becomes a lifetime of return visits.
The SIM card problem — and the fix
This is the part of Southeast Asia travel that has historically broken even seasoned overlanders. Six countries on this route, six entirely separate carrier networks, no roaming agreements between any of them. The traditional solution was to buy a local SIM at each border — at airports, at land crossings, sometimes at carrier shops in town. The pricing is opaque, the staff often don’t speak English, and the airport kiosks are notorious for charging four to five times the local rate to anyone who looks like they just got off a long flight. Tourist SIMs in Bangkok, Hanoi, and Bali have been the subject of consumer warnings for years.
A regional eSIM ends the question. An IbiPoint Asia plan covers Thailand, Cambodia, Vietnam, Laos, Malaysia, and Indonesia on a single activation. It switches networks automatically every time you cross a border or land at a new airport. No carrier shops. No top-ups in three different currencies. No SIM swap that risks losing your existing card. The eSIM activates before you fly to Bangkok and works from the moment you land, with the same plan, same account, and same support reachable across the entire trip.
And here is some genuinely useful news that landed recently: IbiPoint just rolled out the full shop, account, and checkout experience in Thai, Vietnamese, Indonesian, Khmer, and Lao — the five mainland Southeast Asian languages of every country on this route. The same plans, the same prices, the same support, now available in the language your destination actually speaks. For local SIM-card sellers in Bangkok and Bali whose business has historically depended on language friction and information asymmetry, this is mildly inconvenient news. For travellers, it is the kind of small fix that quietly removes one more piece of friction from a long trip.
200+ countries covered on one plan. Five languages added this month. One activation, end to end. The eSIM is not the trip — the trip is the trip — but it is the thing that lets you stop thinking about connectivity and start thinking about the next bowl of phở.
What to eat across the route
Southeast Asia is, by general consensus, the best eating region in the world per dollar spent. The five countries on this route each have distinct cuisines, and travelling them in sequence is a kind of crash course in the entire family.
Thai food at its best is balance — sweet, sour, salty, spicy, bitter, all in the same mouthful. Som tam (green papaya salad) at a street stall in Bangkok. Khao soi (curry noodle soup) from the north. Pad krapao moo with a fried egg and steamed rice, eaten standing at a vendor’s metal counter. The cooking outside the famous restaurants is at least as good as the cooking inside them, and often better.
Cambodian food is the route’s quiet surprise — sweeter and more delicate than its neighbours, with French-colonial influences in the breads and pâtés, and freshwater fish from the Tonlé Sap lake as the regional staple. Amok, a coconut-curry fish steamed in a banana leaf, is the national dish and worth seeking out at one of the small Khmer restaurants near the riverside in Phnom Penh.
Vietnamese food needs little introduction. Phở in the morning, bún bò huế in central Vietnam, bún chả in Hanoi, bánh xèo (the savoury pancake) in the south, cà phê sữa đá (iced coffee with condensed milk) at every break in between. Vietnamese cooking is fresher and lighter than its neighbours — herbs in volume, broths made from scratch, almost no dairy — and it is the food most travellers ask about by name long after the trip ends.
Lao food is closer to northern Thai cooking than to Vietnamese — sticky rice eaten with the hands, laap (the minced meat salad with toasted rice powder), grilled river fish, jaew (the chilli dipping sauces) by the bowlful. The flavours are louder than Thailand’s and the portions are smaller. It is also the cheapest food on the route.
Malaysian food is the genuine fusion of the trip — Malay, Indian, and Chinese all cooked side by side in the same hawker centres, often by families who have been doing it for three generations. Char kway teow. Laksa. Roti canai. Hainanese chicken rice. A long lunch at a hawker centre in George Town or Kuala Lumpur is one of the route’s quiet highlights. Indonesian food on Bali finishes the trip with sambal — the chilli relish that defines Indonesian cooking — alongside babi guling (suckling pig), bebek betutu (smoked duck), and the daily nasi campur plates that are a self-portrait of every household’s pantry.
Practical tips for the route
Book international flights into Bangkok and out of Denpasar, not return flights to the same city. Open-jaw tickets cost roughly the same as return tickets and save you the back-track. Within the trip, book the long-distance flights (Hanoi to Vientiane, Kuala Lumpur to Denpasar) two to four weeks ahead for the best fares. The buses and trains can be booked the day before or even on the day at every stop.
Visas. Most Western passport holders get visa-free or visa-on-arrival entry to every country on this route. Vietnam now offers a multi-entry e-visa valid for 90 days, which is the smartest option if you want flexibility. Check your country’s specific status a week before you fly — the rules change.
Carry cash. ATMs are everywhere in the cities and reliable in tourist areas. Smaller towns, night markets, tuk-tuk drivers, and warungs in Bali are cash-only. Pull larger sums less often to minimise ATM fees. USD is widely accepted as a backup in Cambodia and Laos; otherwise stick to local currency.
Hydrate, sleep, and slow down. The single most common mistake on this trip is treating it like a European itinerary — racing between stops, eating on the move, getting four hours of sleep before the night bus. Southeast Asia in May is 32–35°C with high humidity. The locals slow down in the middle of the day for a reason. Your body will tell you when you have ignored the message. Build rest days into the itinerary — at least one for every five travel days.
Get connected before you fly. The region runs on apps. Grab and Gojek for taxis (sometimes the only honest way to get a fair fare from an airport). Klook and 12Go for booking buses, trains, and ferries. Google Translate for menus. Google Maps for everything. An IbiPoint Asia plan is the one piece of kit that does the work of six local SIMs across the entire route, with no swap, no top-up, no risk of losing a card while changing it at a Bangkok kiosk. It activates before you leave home and works from the moment you land.
The Bangkok to Bali state of mind
There is a particular feeling that only this trip delivers. You wake up on a sleeper train as the sun comes over the Mekong. You eat a bowl of soup at a plastic stool on a Hanoi pavement, surrounded by motorbikes, and it costs €1.50 and it is the best soup you have ever had. You cross a border on foot and watch the alphabet on the road signs change. You meet a German engineer in a guesthouse in Luang Prabang who has been on the road for nine months and is still finding it interesting. You arrive in Bali and realise, looking back over twenty-one days of photographs, that you have lived more in three weeks than you did in the previous three months at home.
The route is not a luxury holiday. It is not even the most efficient way to see the region. It is something better than either of those things — it is the trip that taught a generation of travellers how to travel, and it is still doing the job. The food is still cheaper than home. The infrastructure is better than ever. The connectivity is finally solved. The people are, as they have always been, the warmest hosts in the world for travellers willing to show up with curiosity and good manners.
The trip is the trip. The countries are the countries. The bowl of phở at 7 a.m. in Hanoi tastes the same as it always has.
Go now. The road is open.
