Vietnam and Cambodia reward first-time visitors with epic scenery, deep culture, and unforgettable food—but only if you keep the route tight. The biggest mistake travelers make is trying to “see everything” and losing days to long transfers. This 10-day itinerary solves that by focusing on high-impact highlights, smart flights between regions, and realistic pacing. A strong plan looks like this: Days 1–6 in Vietnam (Hanoi → Ha Long Bay → Hoi An → Ho Chi Minh City), then Days 7–10 in Cambodia (Phnom Penh → Siem Reap/Angkor). Fly between regions where needed, and if you want an overland border crossing, the HCMC → Phnom Penh bus takes about 6–7 hours. For visas, Vietnam’s e-visa portal allows up to 90 days (single or multiple entry), and Cambodia’s official e-visa site is evisa.gov.kh.
