Overland via Phnom Penh

12-14 hours (2 segments)600,000 - 1,200,000₫ total

Giant Ibis, Mekong Express, The Sinh Tourist, various local operators

The overland route passes through Cambodia, making it a journey rather than just a transfer. Take a bus or fly from Bangkok to Phnom Penh (Cambodia), then a bus from Phnom Penh to Saigon. The Bangkok to Phnom Penh leg takes 10-12 hours by bus or 1 hour by flight. The Phnom Penh to Saigon leg takes 6-7 hours by bus. This route is best suited for travelers who want to include Cambodia in their itinerary.

Pros

  • +Turns the journey into a multi-country Southeast Asian adventure through Cambodia
  • +Opportunity to spend 1-3 days in Phnom Penh (Royal Palace, Killing Fields, riverside)
  • +Can extend to include Siem Reap and Angkor Wat — one of the world's greatest sights
  • +Giant Ibis and Mekong Express buses from Phnom Penh to Saigon are comfortable and reliable

Cons

  • -Total overland journey takes 12-14 hours minimum without stops (usually spread over 2+ days)
  • -Requires a Cambodia visa — available on arrival ($30 USD) or as an e-visa
  • -Thai-Cambodia border crossing at Poipet/Aranyaprathet can be slow and chaotic
  • -Multiple vehicle changes and border formalities make it logistically complex
Booking Tip: Book Giant Ibis (giantibis.com) for the Phnom Penh to Saigon bus — widely considered the best cross-border operator in the region. Comfortable seats, free Wi-Fi, and a professional operation. For Bangkok to Phnom Penh, consider flying with AirAsia (1 hour, from $40 USD) rather than the 10-12 hour bus. Book Cambodia e-visas in advance at evisa.gov.kh to skip the on-arrival queue.

Various airlines and bus operators

Rather than treating the Bangkok-Saigon connection as a simple transfer, many travelers turn it into a multi-destination trip through Cambodia. The classic route is Bangkok → Siem Reap (Angkor Wat, 2-3 days) → Phnom Penh (1-2 days) → Saigon. This adds 4-7 days to your trip but includes two of Southeast Asia's most important destinations. Flights between these cities are short and affordable.

Pros

  • +Includes Angkor Wat — one of the world's most spectacular archaeological sites
  • +Phnom Penh's Royal Palace, Silver Pagoda, and Tuol Sleng Museum are deeply powerful
  • +Short flights between Bangkok, Siem Reap, Phnom Penh, and Saigon (all under 2 hours)
  • +Creates an epic Southeast Asian three-country itinerary that covers incredible ground

Cons

  • -Adds 4-7 days to your overall trip — requires more time and budget
  • -Cambodia visa required ($30 USD on arrival or e-visa)
  • -Multiple flights add up in cost even with budget carriers
  • -Requires more planning and flexibility in your itinerary
Booking Tip: Route: Bangkok → fly to Siem Reap (AirAsia, 1 hour) → bus to Phnom Penh (6 hours, Giant Ibis) → bus to Saigon (6-7 hours, Giant Ibis). Or fly each segment for speed. Book Angkor Wat temple passes at the official ticket office (1-day $37, 3-day $62). This is one of Southeast Asia's best multi-country itineraries and worth the extra time if your schedule allows.

Visa Considerations

Vietnam Visa

Most nationalities need a visa for Vietnam. The e-visa ($25 USD, 90-day validity) is available for 80+ nationalities at evisa.xuatnhapcanh.gov.vn — apply at least 3 working days before travel. Several nationalities including UK, Germany, France, Italy, Spain, Japan, and South Korea enjoy 45-day visa-free entry. Always check current requirements for your nationality as policies change frequently.

Cambodia Visa (If Transiting)

If you are traveling overland via Cambodia, you need a Cambodia tourist visa. This is available on arrival at airports and land borders for $30 USD (bring a passport photo). Alternatively, apply for an e-visa at evisa.gov.kh ($36 USD including processing fee) to skip the queue. The Cambodia visa allows a 30-day stay — more than enough for a transit with stops in Phnom Penh and Siem Reap.

Border Crossings

The Phnom Penh to Saigon bus crosses at the Moc Bai/Bavet border — this is a straightforward, well-organized crossing. Giant Ibis buses handle it efficiently with minimal waiting. The Thailand-Cambodia border at Aranyaprathet/Poipet is more chaotic — beware of unofficial "helpers" charging fees. Cross early in the morning for shorter queues. Have your visas arranged in advance when possible.

Currency Tips

Thailand uses Thai Baht (THB), Cambodia uses US Dollars and Cambodian Riel (KHR), and Vietnam uses Vietnamese Dong (VND). ATMs are widely available in all three countries. Cambodia is unique in accepting US Dollars almost everywhere — carry small USD bills for convenience. Exchange currency at official exchange counters, not at borders where rates are poor. Grab works in all three countries for transparent transport pricing.

Our Recommendation

Best Overall

Direct Flight

For most travelers, a direct flight is the obvious choice. At 1.5 hours and from 1,500,000d, it is fast, affordable, and lets you maximize time in both cities. Book AirAsia from Don Mueang for the cheapest fares or Vietnam Airlines from Suvarnabhumi for included luggage and comfort. Compare fares on Google Flights.

Best Adventure

Via Cambodia

If you have 4-7 extra days, routing through Cambodia transforms a simple transfer into an epic three-country journey. Fly Bangkok to Siem Reap (Angkor Wat), bus to Phnom Penh, bus to Saigon. This is one of Southeast Asia's best backpacker routes and includes some of the region's most powerful cultural sites.

Best for Budget

AirAsia Flash Sale

AirAsia regularly offers flash sales with Bangkok-Saigon fares below 1,000,000d ($40 USD). Follow AirAsia on social media and enable app notifications for sale alerts. These fares are hand-luggage only but unbeatable on price. Even at full price, budget flights are cheaper than the overland bus route when you factor in Cambodia visa costs and accommodation.

Frequently Asked Questions

A direct flight takes just 1.5 hours. AirAsia, VietJet Air, Thai Airways, and Vietnam Airlines operate multiple daily flights. Budget fares start from 1,500,000₫ ($60 USD) when booked in advance. Factor in 1-2 hours for airport transfers at each end, making the total door-to-door time approximately 4-5 hours. This is the only practical option for travelers with limited time.
Most nationalities need a visa for Vietnam. The easiest option is the Vietnam e-visa, available online at evisa.xuatnhapcanh.gov.vn for citizens of 80+ countries. The e-visa costs $25 USD, allows a 90-day stay, and is processed in 3 working days. Some nationalities (UK, Germany, France, Italy, Spain, Japan, South Korea) get 45-day visa-free entry. Check your nationality's specific requirements before traveling.
Yes, via Cambodia. The route is Bangkok → border at Aranyaprathet/Poipet → Siem Reap or Phnom Penh → Saigon. The full overland journey takes 2-3 days with stops. You will need a Cambodia transit or tourist visa ($30 USD on arrival at the border). The Phnom Penh to Saigon bus (Giant Ibis, 6-7 hours) crosses the Moc Bai border — a much smoother crossing than Poipet. This is a rewarding journey but time-intensive.
If you have the time, absolutely. Adding Siem Reap (Angkor Wat, 2-3 days) and Phnom Penh (1-2 days) creates one of Southeast Asia's best three-country itineraries. Angkor Wat alone justifies the detour — it is one of the world's most extraordinary archaeological sites. The Giant Ibis bus from Phnom Penh to Saigon is comfortable and the border crossing is straightforward. Budget an extra 4-7 days and $200-400 USD for the Cambodia addition.
Both airports serve Saigon. AirAsia operates from Don Mueang Airport (DMK), which is the older, budget-carrier airport. Thai Airways, Vietnam Airlines, and VietJet typically operate from Suvarnabhumi Airport (BKK), the main international airport. Always check which airport your flight uses before booking — they are 30+ kilometres apart and transferring between them takes 45-90 minutes depending on traffic.
