Indochina combinations are popular and doable from 10 days (tight) to three weeks (comfortable). The art is border logic and not over-flying.
10–12 days
Pick two countries. Vietnam + Cambodia (Angkor) or Thailand + Cambodia are cleaner than trying all three.
2–3 weeks
All three become realistic: Thailand’s north or Bangkok, Cambodia’s temples, Vietnam’s central or southern stretch — ordered to minimise backtracking.
What we watch for
- Visa-on-arrival / e-visa timing
- Overland vs short-hop flights
- Heat in April / rain patterns by coast
Takeaway
Share your must-sees in each country — we’ll propose an order that feels like one journey, not three holidays stapled together.
