Vietnam, Cambodia & Laos in One Trip: 3 Routes That Work

Vietnam, Cambodia and Laos look compact on a map and are anything but. The single biggest mistake in multi-country planning is underestimating internal transit: a badly-built three-country trip can burn five of fourteen days in airports and border posts. These are three routings we run repeatedly because they work.

Route 1 — The classic north-to-south, 14 days

Hanoi (3) → Ha Long or Bai Tu Long Bay (1 night on board) → Hoi An via Da Nang (3) → Ho Chi Minh City (2) → Siem Reap (3) → home.

Two domestic Vietnamese flights and one short international hop into Siem Reap. It gives you the country’s three anchors plus Angkor without any long overland day, and it is the routing we recommend for a first Indochina trip.

Route 2 — Overland Mekong, 16 days

Luang Prabang (3) → Vientiane (1) → flight to Hanoi (3) → Ha Long (1 night) → flight to Ho Chi Minh City (2) → Mekong Delta and overland border into Cambodia → Phnom Penh (2) → Siem Reap (3).

This is the version for travellers who want the river and the border crossings to be part of the trip rather than an obstacle. The Delta-to-Cambodia leg is handled by our own vehicles on both sides — the same crew hands you over, which is where most agency trips wobble.

Route 3 — Two countries, done properly, 10 days

Siem Reap (3) → flight to Da Nang for Hoi An (3) → Hanoi (2) → Ha Long or Lan Ha Bay (1 night) → home.

If you have ten days, three countries is too many. Dropping Laos buys you slower mornings, and Laos genuinely deserves its own trip — it is the country clients most often say they wished they had given more time.

Practical points that decide the routing

• Fly the long legs. Hanoi–Ho Chi Minh City is a two-hour flight or a 35-hour road journey. Overland is a choice, not a saving.
• Visas. Requirements change; we confirm the current rules for your nationality in writing before you book flights, and we schedule the border days so nothing depends on a single office closing time.
• Seasons collide. Central Vietnam’s wettest months (September–November) are Angkor’s best. When the calendar forces a compromise, we reorder the route rather than shorten it.
• One operator, three countries. Our own offices handle each leg, so there is no handover to a third agency at the border and one contact stays reachable 24/7 while you travel.
