The Classic Southeast Asia Route
The most popular backpacking route runs from Bangkok south through Thailand's islands, across to Cambodia (Siem Reap and Phnom Penh), into Vietnam from south to north, and optionally through Laos before looping back to Bangkok. This route works because visa logistics flow smoothly and transport connections are well-established between all these countries. For a 2 to 3 month trip, a good breakdown is: Thailand (3–4 weeks), Cambodia (1–2 weeks), Vietnam (3–4 weeks), and Laos (1–2 weeks). If you have less time, pick two countries and explore them properly rather than rushing through four. Bangkok is the ideal starting point — cheap flights from everywhere, excellent hostel infrastructure, and an easy introduction to the region.

Daily Budgets by Country
Southeast Asia remains one of the world's most affordable travel regions, though prices have increased in popular tourist areas. Realistic daily budgets for a backpacker (hostel dorm, local food, public transport, one activity): Thailand $30–45, Vietnam $25–40, Cambodia $25–35, Laos $25–35, Indonesia (Bali) $30–50, Myanmar $35–50, Philippines $25–40. These budgets stretch further outside tourist hotspots. A meal at a local restaurant or street stall costs $1 to $3 across the region. A private room in a guesthouse runs $10 to $25 per night. Hostel dorms are $5 to $12. The biggest budget variables are alcohol (cheap beer at local bars, expensive cocktails at tourist spots), diving and adventure activities ($30–80 per day), and inter-country flights versus overland travel.
Must-Have Experiences Across the Region
In Thailand, explore Bangkok's temples and street food, then head to Chiang Mai for cooking classes and temple-dotted mountains, and the islands (Koh Lanta for relaxation, Koh Tao for diving, Koh Phangan for the Full Moon Party). In Cambodia, sunrise at Angkor Wat is a bucket-list moment — spend 3 days exploring the vast temple complex. The Kampot riverside town and Koh Rong island offer quieter escapes. Vietnam's highlights span the entire country: Hanoi's Old Quarter chaos, Ha Long Bay's limestone karsts, Hoi An's lantern-lit streets and tailors, the Hai Van Pass motorbike ride, and Ho Chi Minh City's war history and vibrant food scene. In Laos, slow-boat down the Mekong from the Thai border to Luang Prabang, where saffron-robed monks collect alms at dawn and waterfalls cascade through turquoise pools at Kuang Si.
Visas, Health, and Safety
Visa requirements vary by nationality but have simplified considerably. Thailand offers visa-free entry for 30 to 60 days for most nationalities. Vietnam requires an e-visa (apply online, approved within 3 business days) for 90-day stays. Cambodia offers visa on arrival for $30 at airports and land borders. Laos also offers visa on arrival for $30 to $42 depending on nationality. Indonesia grants visa-free entry for 30 days or visa on arrival for 30 days (extendable). See a travel doctor 4 to 6 weeks before departure for recommended vaccinations (typically hepatitis A and B, typhoid, and tetanus). Antimalarials may be advised for rural areas. Drink bottled or filtered water only. Travel insurance is essential — make sure it covers motorbike accidents, as this is the most common medical claim in Southeast Asia. Keep photocopies of your passport and cards in a separate location from the originals.
Packing and Getting Around
Pack light — a 40 to 50 liter backpack is ideal. You can buy anything you need cheaply throughout the region (toiletries, clothing, adapters). Essentials: quick-dry clothing, a rain jacket, reef-safe sunscreen, a headlamp, a microfiber towel, a padlock for hostel lockers, and a universal power adapter. Leave jeans at home — lightweight pants and shorts are all you need in the tropical heat. Overland transport between cities is cheap and efficient. Sleeper buses and trains run overnight routes, saving accommodation costs. In Vietnam, the Reunification Express train from Ho Chi Minh City to Hanoi (or segments of it) is a classic journey. Budget airlines (AirAsia, VietJet, Lion Air) connect major cities for $20 to $60 if booked in advance. Within cities, Grab (the regional Uber equivalent) is reliable and affordable.
