A Thailand Cambodia Vietnam tour combines three of Southeast Asia’s most rewarding destinations in one journey. You can explore Bangkok’s temples, cruise through Halong Bay, walk around historic Hoi An and see Angkor Wat without planning three separate holidays. However, the route must be organised carefully to avoid unnecessary flights and rushed sightseeing. This guide Smart Asia Travel explains how many days you need, which destinations to include, when to travel and what costs to expect. It also provides a practical 14-day itinerary for first-time visitors who want culture, food, history and natural scenery in a balanced trip.

Suggested 14-Day Thailand Cambodia Vietnam Tour Itinerary

This route covers the highlights of all three countries while keeping travel manageable. It follows Bangkok–Chiang Mai–Hanoi–Halong Bay–Hoi An–Ho Chi Minh City–Siem Reap, similar to Smart Asia Travel’s established multi-country itinerary. View the available Vietnam and Indochina tours.

Days Destination Main experiences
1–3 Bangkok and Chiang Mai Temples, markets and northern Thai culture
4–6 Hanoi and Halong Bay Old Quarter exploration and overnight cruise
7–8 Hoi An Ancient Town, food and countryside
9–11 Ho Chi Minh City and Mekong Delta History, city life and river communities
12–14 Siem Reap Angkor temples and Khmer culture

Days 1–3: Bangkok and Chiang Mai, Thailand

Begin in Bangkok, an accessible international gateway with a wide choice of flights and hotels. Spend the first day resting, exploring the neighbourhood around your hotel and becoming familiar with the climate.

Use the second day for Bangkok’s essential attractions. A private city tour can combine the Grand Palace, Wat Pho, riverside neighbourhoods and a local market without spending too much time arranging transport.

Fly to Chiang Mai on the third day. Depending on the arrival time, visit an evening market or join a guided food tour. Chiang Mai adds a quieter northern perspective to the Thailand section of the journey.

  • Allow time after arrival: Avoid scheduling a full sightseeing programme immediately after a long international flight.
  • Dress appropriately at temples: Cover shoulders and knees, and be prepared to remove your shoes before entering certain buildings.
  • Choose a central hotel: Staying near the Old City or riverside areas can reduce daily travel time.

Travellers who prefer a slower itinerary can omit Chiang Mai and add an extra night in Bangkok or Vietnam.

Days 4–6: Hanoi and Halong Bay, Vietnam

Fly from Chiang Mai or Bangkok to Hanoi. Vietnam’s capital offers historic architecture, active street life and a strong food culture. Spend the first afternoon exploring the Old Quarter and the area around Hoan Kiem Lake.

On the following day, visit selected landmarks such as the Temple of Literature, the Ho Chi Minh complex and a traditional market. Avoid trying to see every museum in one day. A local guide can organise the route around your interests and explain the historical context.

Travel to Halong Bay on day six for an overnight cruise. Most programmes include meals, scenic sailing and activities such as cave visits or kayaking. Staying overnight gives you more time on the bay than a rushed day trip.

Halong Bay

Days 7–8: Hoi An, Vietnam

After returning from Halong Bay, fly from Hanoi to Da Nang and continue by road to Hoi An. This section provides a useful break between the larger cities.

Spend one day exploring the Ancient Town, including its historic houses, assembly halls, riverside streets and local shops. In the evening, the centre becomes pedestrian-friendly and is easy to explore on foot.

Use the next day for an activity outside the main heritage area. Suitable choices include a cooking class, bicycle ride, village visit or excursion to My Son Sanctuary. Travellers who need more rest can spend part of the day at An Bang Beach.

Hoi An should not be treated as a quick photo stop. Two nights allow enough time to experience the town during quieter morning hours and enjoy its food without overloading the schedule.

Hoi An

Days 9–11: Ho Chi Minh City and the Mekong Delta

Fly from Da Nang to Ho Chi Minh City. The city provides a clear contrast to Hanoi, with wider boulevards, modern commercial districts and landmarks connected to Vietnam’s more recent history.

A focused sightseeing day may include the War Remnants Museum, Independence Palace, Central Post Office and a guided food experience. Cu Chi Tunnels can replace part of the city programme for travellers interested in wartime history.

Reserve another day for the Mekong Delta. Ben Tre is a practical option for a day trip, with boat journeys, village roads and small local workshops. An overnight stay is better for travellers who want a deeper experience, although it requires removing another destination or extending the tour.

  • Keep valuables secure: Use a zipped bag and take normal precautions in crowded streets and markets.
  • Plan around traffic: Allow extra transfer time when travelling to the airport.
  • Balance history and daily life: Combine museums with a market, neighbourhood walk or food tour.

Days 12–14: Siem Reap and Angkor, Cambodia

Fly from Ho Chi Minh City to Siem Reap for the final section of the journey. Spend at least two days exploring Angkor rather than trying to visit the entire complex in a few hours.

The first temple day can include Angkor Wat, Angkor Thom and Ta Prohm. Start early to avoid some of the heat, but do not turn the day into a race between monuments. A knowledgeable guide can explain the carvings, religious influences and architectural changes.

On the next day, choose smaller temples, visit a local community or take an excursion towards Tonle Sap when seasonal conditions are suitable. Siem Reap also has markets, workshops and restaurants that deserve time outside the archaeological park.

Finish the tour in Siem Reap or connect through Bangkok, Hanoi or Ho Chi Minh City for your international flight.

How Many Days Do You Need for Three Countries?

The ideal duration depends on how many flights you are willing to take and whether you prefer major highlights or slower local experiences.

Duration Suitable itinerary Travel pace
10–12 days Bangkok, Hanoi, Halong Bay and Siem Reap Fast
14–16 days Major highlights across all three countries Balanced
18–21 days Additional cities, countryside or beach time Relaxed

A 14-day Thailand Cambodia Vietnam itinerary is suitable for most first-time visitors. It provides a useful overview but still involves several flights. Extending the journey to 18 or 21 days creates room for Chiang Mai, Hue, the Mekong Delta or a beach stay.

If you only have ten days, limit the tour to four main bases. Adding too many one-night stops usually increases costs and reduces meaningful sightseeing time.

Best Time for a Thailand Cambodia Vietnam Tour

There is no single month that guarantees perfect weather across every destination. Vietnam extends through several climate zones, while Thailand and Cambodia are influenced by seasonal monsoons.

November to February is a popular period for a three-country journey because conditions are often cooler and drier in Bangkok, Siem Reap and southern Vietnam. Thailand’s tourism authority identifies a cooler period with drier breezes as part of the country’s seasonal cycle.

March and April can also work, especially for central Vietnam, but temperatures may become very high in Thailand and Cambodia. Vietnam’s central coast often has favourable conditions during spring, although northern and southern regions follow different patterns.

Travelling from May to October is still possible. Visitors should expect heat, humidity and heavy showers, but rain often occurs in shorter periods rather than lasting all day. This season may also offer better hotel availability.

Check the expected weather for each city instead of relying on a single regional forecast.

Why Plan Your Multi-Country Tour with Smart Asia Travel?

A three-country journey involves several hotels, guides, airport transfers and regional flights. Coordinating these services through one destination management company can reduce gaps between separate bookings.

Smart Asia Travel has more than 12 years of regional experience and designs private journeys across Vietnam, Thailand and Cambodia. The itinerary can be adjusted according to your arrival city, preferred hotel category, interests and available time.

Local guides provide context that is difficult to gain from transport and admission tickets alone. Travellers also receive support during the journey if a flight changes, a transfer is delayed or the programme needs to be adjusted.

Plan Your Thailand Cambodia Vietnam Tour

A well-planned Thailand Cambodia Vietnam tour needs at least 14 days to cover the main highlights at a reasonable pace. Bangkok, Hanoi, Halong Bay, Hoi An, Ho Chi Minh City and Siem Reap create a balanced route combining temples, history, food and natural scenery.
