Documents & visas
- Passport valid for at least 6 months beyond your return date
- At least two blank passport pages for stamps
- Check visa requirements per country — many offer e-visas (Vietnam, India, Sri Lanka, Indonesia)
- Print return-flight confirmation — sometimes asked at check-in
- Save digital + paper copies of passport in separate bags
Apply for e-visas only through the official government portal. Lookalike sites charge 3–5× the official fee. The official Vietnam portal is evisa.gov.vn; for India it's indianvisaonline.gov.in.
Health & vaccinations
Visit a travel clinic 4–6 weeks before departure — some vaccines need multiple doses. Common recommendations across Asia:
- Hepatitis A — recommended everywhere
- Typhoid — recommended for South/Southeast Asia
- Tetanus booster — if more than 10 years since last dose
- Japanese Encephalitis — if rural areas for more than 30 days
- Rabies pre-exposure — for long stays or remote travel
- Malaria tablets — for specific regions only, not blanket
Bring a small medical kit: rehydration salts, paracetamol, anti-diarrheal, antihistamines, plasters, a strong reef-safe sunscreen and DEET-based insect repellent (30%+ for evenings).
Travel insurance — not optional
A single hospital night in Bangkok or Singapore can cost more than your entire trip. Comprehensive travel insurance with medical evacuation is non-negotiable.
- Minimum $100,000 medical coverage, $500,000 for evacuation
- Explicit coverage for motorbike use (if you'll rent one)
- Coverage for adventure activities you actually plan to do
- Reputable providers: SafetyWing, World Nomads, IMG, Allianz
Money & cards
- Notify your bank of travel dates to avoid card freezes
- Bring two cards on separate networks (Visa + Mastercard)
- Wise or Revolut multi-currency card — lowest FX fees
- Some USD or EUR cash for visa-on-arrival fees and emergencies
- Avoid airport currency exchange — rates are 10–15% worse
ATMs in Thailand, Vietnam and Indonesia often charge $5–7 per withdrawal — take out larger amounts less often. Cambodia and parts of Laos accept USD directly.
Phone & connectivity
A local eSIM is the easiest option in 2025. Activate before you land:
- Airalo and Holafly — regional Asia eSIMs from $5
- Or buy a local SIM at the airport on arrival (always cheap in Asia)
- Download offline Google Maps for every city you'll visit
- Install Grab, GoJek and your bank app before leaving home
- Enable WhatsApp — universally used in Asia
Packing for islands & nature
Pack light. Laundry in Asia costs $1–3 per kilo and turns around in 24 hours. A 40L backpack handles a month easily.
- Lightweight linen or quick-dry clothing — humidity is real
- One set covering shoulders and knees for temple visits
- Reef-safe sunscreen — many Asian islands ban oxybenzone-based formulas
- Compact rain jacket — even outside monsoon, downpours are sudden
- Reusable water bottle with built-in filter (LifeStraw, Grayl)
- Quick-dry travel towel and a sarong (doubles as blanket, scarf, beach mat)
- Universal travel adapter — Asia uses several plug types
- A small dry bag for boat trips and waterfall hikes
Cultural readiness
- Cover shoulders and knees at all religious sites
- Remove shoes before entering temples and most homes
- Never touch anyone's head — sacred in Buddhist cultures
- Use your right hand for giving, receiving and eating in South Asia
- Learn five words: hello, thank you, sorry, yes, no — in each country's language
Travel slowly. Two countries in a month, deeply, will give you more than five countries on a checklist. Asia rewards patience.
