Then the Vietnam and Cambodia tour should be at the top of your travel list. These two neighboring countries in Southeast Asia offer an incredible mix of culture, history, and natural beauty. From Vietnam’s bustling cities and emerald bays to Cambodia’s ancient temples and vibrant culture, this journey combines stunning landscapes, rich history, and authentic local life.

1.Best Time to Visit Vietnam and Cambodia

So, when is the best time to visit Vietnam and Cambodia? Since both countries have tropical climates, the weather varies a lot by region and season. If you’re planning a combined trip, choosing the right time is key to enjoying everything from mountain treks to temple tours.

• November – March (Peak Season): The sweet spot, best time to visit both Vietnam and Cambodia. At this time, the weather is cool, dry, and comfortable across both countries so it’s perfect for trekking in Sapa, Halong Bay cruises, Ho Chi Minh city, …and exploring Angkor Wat in Cambodia
• May- August: The summer months in Vietnam and Cambodia bring hot, humid weather with frequent rain showers, especially in the afternoons. Temperatures often range between 28°C and 35°C, and humidity can feel intense in the cities. Despite this, the rains are usually short-lived, and the landscapes turn incredibly green and vibrant.
  • Vietnam: Central and southern beaches such as Da Nang, Nha Trang, and Phu Quoc are still beautiful for sunbathing and swimming. Northern areas like Hanoi and Sapa are hotter, but rain helps cool the air.
  • Cambodia: Expect warm, wet days, but this is when Angkor Wat looks its most dramatic against lush, rain-soaked scenery. Fewer tourists mean quieter temples and better photo opportunities.

• September-October: This is the shoulder season, meaning you’ll find fewer tourists, lower prices, and stunning natural scenery.
  • Vietnam: In the north, autumn arrives with cool breezes and clear skies, perfect for Hanoi city walks, Halong Bay cruises, and trekking in Sapa. This is also the season when the rice terraces in places like Mu Cang Chai and Sapa glow in golden harvest colors. And central Vietnam is still transitioning out of the rainy season, so you may encounter occasional storms, but Hue and Hoi An are less crowded and beautifully atmospheric. In the south, conditions are improving as the wet season tapers off, making the Mekong Delta and Phu Quoc increasingly enjoyable.
  • Cambodia: The rains begin to ease, leaving behind lush green landscapes and cooler temperatures. Temples at Angkor are especially photogenic, framed by dramatic skies and reflections in the moats. At this time, there are fewer crowds, which means you can explore Siem Reap and Phnom Penh at a slower, more peaceful pace.

2.How to Travel Between Vietnam and Cambodia

One of the best things about planning a Vietnam–Cambodia trip is how easy it is to travel between the two countries. Depending on your budget, time, and travel style, you’ve got several great options:

 

By Air 

Vietnam to Cambodia flight is the fastest and most convenient way. There are daily direct flights connecting Hanoi, Ho Chi Minh City, and Da Nang with Phnom Penh and Siem Reap. It’s a perfect choice if you want to save time and maximize sightseeing.

How long does it take from Vietnam to Cambodia by air?

There are 2 most popular routes from Vietnam to Cambodia: From Noi Bai International Airport to Siem Reap-Angkor International Airport with an average flight time of  1 hour and 46 minutes. And from Tan Son Nhat International Airport to Siem Reap-Angkor International Airport with an average flight time of about 1 hour.

By Bus 

A budget-friendly choice, especially for backpackers. The most popular route is Ho Chi Minh City to Phnom Penh, taking around 6-7 hours. Tourists can choose comfortable sleeper buses that are also available for longer routes, and tickets are very affordable.

 

By Boat 

For tourists who find something more scenic, taking the Mekong River speedboat between Chau Doc (Vietnam) and Phnom Penh is a great idea to do. The speedboat journey along the Mekong River between Châu Đốc (Vietnam) and Phnom Penh (Cambodia) usually takes about 4.5 to 6 hours. It’s slower than flying but offers an unforgettable journey past floating villages, lush riverbanks, and local life along the Mekong.

So which option should you choose?

• Short on time? Fly.
• On a budget? Take the bus.
• Love slow travel and scenery? Go for the boat.
