Deciding how much ground to cover
The instinct on a first visit is to try to see all three countries at once, and it's a reasonable one — mountain scenery in the north, beach and imperial history through the centre, temple culture and delta life further south and west, all within a few hours' flying time of each other.
The trade-off is pace. Three countries in ten days means mostly transit; three countries in three weeks leaves room to actually settle into each place. If time is tight, it's usually better to go deep on one country and save the rest for a return trip than to skim across all three.
When to travel across all three
No single month suits every region perfectly, but the window from November through April lines up reasonably well across the board — dry season in Cambodia and southern Laos, cool and dry in northern Vietnam, and past the worst of central Vietnam's autumn storms.
Booking further ahead also opens up the region's festival calendar, from Tet in Vietnam to Lao New Year and Khmer New Year, each landing at a slightly different point in the dry season.
Vietnam at a glance
- Hanoi — the capital, built around a lake and an old trading quarter, and the natural base for exploring Vietnam's north.
- [Ha Long Bay](destinations/ha-long-bay) — around 1,900 limestone islands, usually visited on an overnight cruise rather than a day trip.
- Hue and Da Nang — imperial history and a developing coastal city, a short drive apart in central Vietnam.
- [Mekong Delta](destinations/mekong-delta) — a working river landscape south of Ho Chi Minh City, best seen from a boat, ideally at a floating market before mid-morning.
Laos at a glance
- [Vientiane](destinations/vientiane) — the capital, quieter and lower-rise than most Southeast Asian capitals, with sights including Pha That Luang and the Patuxai monument.
- [Xieng Khouang](destinations/xieng-khouang) — a highland plateau best known for the Plain of Jars, alongside hot springs near Muang Kham.
- [Luang Prabang](destinations/luang-prabang) — a UNESCO-listed former royal capital with temple architecture and river views.
- Riverside villages along the Mekong, reachable on day trips or as stops on a longer boat journey.
Cambodia at a glance
- [Phnom Penh](destinations/phnom-penh) — the capital, with royal palaces, museums and a riverside promenade along the Tonle Sap.
- [Siem Reap](destinations/siem-reap) — the base for the Angkor temple complex, and a town with its own night market and old quarter worth an evening.
- A local guide is worth arranging in Siem Reap if you want the lesser-known corners of the temples explained rather than just walked past.
Moving between the three
Overland border crossings connect all three countries, and some of the most memorable stretches of a combined trip happen on the road between them rather than in the destinations themselves — the drive from Vietnam's Mekong Delta into Cambodia, for instance, or the river crossing from southern Laos toward Cambodia's north.
Where distances get long, short regional flights between Hanoi, Siem Reap, Luang Prabang and Ho Chi Minh City save a day of driving without losing the overland feel of the rest of the trip.
