Backpacking Southeast Asia: a 3–4 week route, budget, safety and visas

TUREFF• •0

Southeast Asia is where many people take their first long trip, and for good reason: it is affordable, the food is extraordinary, and there is a well-worn trail of buses, trains and guesthouses that makes it easy to travel independently. This is a classic route for three to four weeks and the practical things that make it go smoothly.

A classic 3–4 week loop

Bangkok, Thailand (3 nights): temples, the Grand Palace, river ferries, street food, and the chaos of the markets.
Northern Thailand (4–5 nights): Chiang Mai for its old city, cooking classes and night markets, and Pai or Chiang Rai if you have time.
Laos (4–5 nights): Luang Prabang for monks, waterfalls and a slower pace. Getting there by slow boat on the Mekong is a popular two-day trip; flying is quicker.
Cambodia (4–5 nights): Siem Reap for the Angkor temples (give it at least two days), then Phnom Penh for its history.
Southern Thailand (5–7 nights): finish on the islands, such as Koh Lanta, Koh Phangan or Koh Tao, or around Krabi.

With only three weeks, drop Laos or the islands. With more time, add Vietnam, which deserves its own two weeks, or Malaysia. Do not try to see everything. Long overland days in heat are tiring, and the best memories usually come from the places you stayed an extra night.

Getting around

Overnight buses and trains save a night's accommodation; Thailand's sleeper trains are a highlight in their own right.
Budget flights link the capitals cheaply and can save a whole day on long routes.
Ride-hailing apps work in most of the big cities and avoid haggling with taxi drivers.
Book through your guesthouse or a reputable agent for minibuses and boats; check reviews.

Budgeting in general terms

Southeast Asia can be very cheap or quite comfortable, depending on your choices. The main things that move your daily spend:

Accommodation: dorm beds and simple guesthouses are the cheapest; private rooms with air-conditioning cost more.
Food: street stalls and local restaurants cost a fraction of Western-style cafés.
Alcohol and activities: these add up faster than anything else. Diving courses, island tours and nights out are where budgets break.
Islands: usually pricier than the mainland.

Set a daily figure before you go, track it for the first week, and adjust. Keep an emergency reserve you never touch.

Money

ATMs are everywhere in cities but often charge a fee per withdrawal, so take out larger amounts less often.
Carry some US dollars in clean, undamaged notes; they are useful in Cambodia, where dollars circulate alongside the local currency.
Cards are widely accepted in cities, much less so in rural areas and markets.

Visas: they vary, so check

Every country on this route has its own rules, and they change. Some offer visa-free entry to many nationalities, some require an e-visa applied for online, and some issue a visa on arrival. Several have introduced online arrival cards to fill in before you land. Check each country's official immigration website, or your own government's travel advice, for your passport, and use only official portals: third-party sites charge extra for the same form.

Safety and health

Road safety is the biggest real risk. Many travellers rent scooters without a licence or experience; accidents are common and often not covered by insurance if you are unlicensed.
Travel insurance is essential. Check it covers the activities you plan.
Watch your drink, be wary of strangers offering "special" tours or gem deals, and agree prices before you get in a tuk-tuk.
Drink bottled or filtered water, use insect repellent, and see a travel clinic well before you go about vaccinations and malaria advice.
Respect local laws, especially around drugs, where penalties can be extremely severe.

Packing light

A 35–45 litre backpack is plenty. Light clothes, one layer for cold buses, a sarong or scarf to cover shoulders at temples, and sandals you can walk in. Planning your route, or just back from one? Share your questions, tips and favourite places in the comments.
