A 6–8 week itinerary through Thailand, Vietnam, Cambodia and Laos.

Drawing a loop around Southeast Asia is a rite of passage for many British travellers, offering a mix of chaotic cities, serene highlands, and islands that look exactly like the postcards. This route, often called the 'Banana Pancake Trail', covers the essential highlights of Thailand, Laos, Vietnam, and Cambodia over a recommended period of three to four months.

Starting Point: Bangkok and the Thai North Most journeys begin at Bangkok’s Suvarnabhumi Airport. From London Heathrow, a direct flight with Thai Airways or British Airways takes roughly 11.5 hours, usually costing between £700 and £900 return.

Bangkok is a sensory overload. Spend your first three days adjusting to the humidity and the time zone. Stay in the Banglamphu area; while Khao San Road is the famous backpacker hub, the neighbouring Soi Rambuttri offers a slightly calmer vibe. A basic private room costs around £20 per night, while a dorm bed is closer to £8. Use the River Taxi (16 THB, about 35p) to reach the Grand Palace rather than an overpriced tuk-tuk.

From the capital, head north to Chiang Mai via the overnight sleeper train. A second-class air-conditioned berth costs about £25 and saves you a night on accommodation. Chiang Mai is the place to settle for a week. It’s cheaper than Bangkok, with incredible street food markets like the North Gate Jazz Co-op area. Dedicated travellers often head further north to Pai, a three-hour journey involving 762 hairpin turns, known for its relaxed mountain atmosphere and £5-a-night bamboo bungalows.

The Slow Boat to Luang Prabang Crossing from Northern Thailand into Laos is a highlight of the trip. From the border town of Chiang Khong, you can board a ‘slow boat’ for a two-day journey down the Mekong River. This costs roughly £40, including a guesthouse stay in the halfway village of Pakbeng.

Luang Prabang is arguably the most beautiful town in Southeast Asia. It’s a UNESCO World Heritage site where French colonial architecture meets golden Buddhist temples. - **Kuang Si Falls:** Rent a moped for £8 a day to visit these turquoise tiered waterfalls. - **Alms Giving:** Wake up at 5:30 am to see the saffron-robed monks collect offerings, but keep a respectful distance. - **Vang Vieng:** Once a notorious party town, it has rebranded as an adventure hub. You can go rock climbing or hot air ballooning over the karst mountains for about £75.

Laos is slightly more expensive for transport than Thailand because of the rugged terrain, but a meal of 'Laos Larb' (minced meat salad) and sticky rice will rarely cost more than £3.

Vietnam’s Coastal Trail From Laos, fly from Luang Prabang to Hanoi (1 hour, £80) to save yourself a 24-hour 'bus from hell'. Vietnam is shaped like an ‘S’, making the route simple: you either go North to South or vice versa.

Start in Hanoi, where the coffee culture is unrivalled. A 'Ca Phe Trung' (egg coffee) at Note Coffee costs £1.50 and is a local staple. Ha Long Bay is the big draw here; avoid the cheapest day trips and opt for a two-day, one-night cruise for around £110 to reach the quieter Lan Ha Bay area.

The journey south is best done via the ‘Reunification Express’ train or cheap internal flights. - **Hoi An:** The most atmospheric stop. Get a tailored suit or dress for £40–£80 and wander the lantern-lit streets. - **Hue:** Visit the Imperial City and the 'Abandoned Waterpark' (Ho Thuy Tien) for some eerie photography. - **Ho Chi Minh City (Saigon):** A whirlwind of motorbikes. Visit the War Remnants Museum (£1.40 entry) for a sobering look at the country’s history.

The Temples of Cambodia Cross the border from Southern Vietnam into Cambodia via a six-hour bus to Phnom Penh (£12). Cambodia uses the US Dollar alongside the Cambodian Riel; keep small denominations of USD handy.

Phnom Penh is home to the Killing Fields and S-21 Prison. While heavy, they are essential for understanding Cambodia’s resilient spirit. From there, take a bus to Siem Reap, the gateway to Angkor Wat. - **Angkor Pass:** A three-day pass costs about £50. It’s worth the extra money over a one-day pass so you can explore the further-flung temples like Banteay Srei without rushing. - **Pub Street:** In Siem Reap, 50p draught beers are the norm, making it the cheapest place on the route for a night out.

If you have time, head south to the islands of Koh Rong or Koh Rong Sanloem. These are less developed than Thai islands, often having limited electricity and no ATMs, but offer pristine white sand and bioluminescent plankton tours for under £10.

The Thai Islands and The South Circle back into Thailand to finish your trip on the islands. If you are coming from Cambodia, a bus to Bangkok and then a flight to Surat Thani or Phuket is the fastest route.

The islands are generally split into two sides: - **The Gulf (East):** Koh Samui, Koh Phangan, and Koh Tao. **Koh Tao** is the cheapest place in the world to get PADI Scuba certified (around £250 for a four-day course). **Koh Phangan** is famous for the Full Moon Party, but the north of the island is actually a quiet yoga and wellness retreat. - **The Andaman (West):** Phuket, Krabi, and Koh Lanta. **Koh Lanta** is the pick for those wanting a more 'authentic' feel, with long empty beaches and great sunset bars.

Expect to pay more here than in the north. A beachfront bungalow will start at £30, and a western-style meal will be £7–£10.

Daily Budgeting and Costs While Southeast Asia is famous for being cheap, prices have risen post-pandemic. - **The 'Shoestring' Budget:** £30–£35 per day. This covers dorm beds, street food, and local buses. - **The 'Flashpacker' Budget:** £50–£60 per day. This allows for private rooms with air-con, some internal flights, and more Western meals/cocktails. - **Visas:** Most British passport holders get 30 days visa-free in Thailand. Cambodia is roughly £28 (e-visa or on arrival). Laos is roughly £35. Vietnam now offers a 45-day visa-free entry for UK citizens, which is a significant saving and time-saver compared to the old e-visa system.

Practical Gear and Health Pack lighter than you think you need. You can get a load of laundry done for £1 in almost any town. - **Travel Insurance:** Do not skip this. Ensure it covers moped riding if you plan to rent one—most policies require a UK motorbike license for the coverage to be valid. - **The 'Bum Gun':** You’ll quickly get used to the spray hoses in toilets; they are often more hygienic than paper in tropical climates. - **GRAB App:** Download this immediately. It is the Uber of Southeast Asia and prevents you from being scammed by unmetered taxis. You can even order food to your hostel. - **Revolution/Monzo:** Take a fee-free travel card. Note that Thai ATMs charge a flat fee of 220 THB (about £5) per withdrawal, so take out the maximum amount allowed each time to save on fees.

Ready to go? The best time to tackle this full loop is between November and February when the weather is dry and relatively 'cool' (around 28-30°C). If you head out in April, be prepared for the heat—it often tops 40°C in Cambodia and Thailand.

Book your first two nights in Bangkok and leave the rest to chance. The beauty of this route is the people you meet in hostel common rooms who will tell you about a hidden waterfall or a village that wasn't on your radar. Start slow, eat everything, and always carry a roll of toilet paper in your day pack.
