For Vietnam, a 5- to 6-day itinerary allows you to catch a glimpse into the rich cultural heritage and spectacular natural landscape, from ancient Hanoi to majestic Ha Long Bay, to the classic Hoi An and the vibrant Ho Chi Minh City. For Laos, visitors can explore the ancient temples of Luang Prabang and the natural beauty of Kuang Si Waterfalls. You can feel the slow pace of life and the hospitality of the people here. Lastly, Cambodia is an attractive destination with the world wonder Angkor Wat and the historical capital Phnom Penh.

Choosing the best time to start your adventure in Vietnam, Laos, and Cambodia in 15 days seems to be difficult since each country has its own climate and weather. But don’t worry too much; we will give you comprehensive information about the climate of those.
Vietnam
Vietnam’s climate varies by region from north to south. Therefore, the ideal time to visit Vietnam depends on which region you want to go to.

During this time, you can enjoy the autumn scenery and the cold winter air. The central region (Hoi An, Hue, and Da Nang) should be visited between February and August, when the sunshine is bright, the beach water is blue, and there are fewer storms. The southern region offers all year-round pleasant weather; however, it is recommended to visit this region from November to April. With average temperatures ranging from 25°C to 32°C, this is an ideal time to explore the Mekong River. If you enjoy the freshness of nature, the rainy season (May to October) is also an interesting experience.

This is the best time to explore waterfalls like Kuang Si, attend cultural festivals, or go boating on the Mekong River. The rainy season, from May to October, has a lot of rainfall.

Some Helpful Tips
The journey to Vietnam, Laos, and Cambodia in 15 days is an excellent opportunity to experience the diversity and beauty of the three countries in Southeast Asia. However, to enjoy the whole journey, you need thorough preparation and tips to make it more interesting. Here are five simple but effective techniques to make this trip an unforgettable memory.
Make a detailed plan
Within 15 days, you can’t go to all the famous attractions, so choose the most popular destinations in each country. In Vietnam, we recommend visiting Hanoi, Hoi An, and the Mekong Delta. In Laos, don’t miss Luang Prabang and Kuang Si Waterfalls. In Cambodia, Angkor Wat and Phnom Penh are indispensable destinations. A reasonable itinerary will help you avoid getting tired from traveling too much but still catch the glory of three nations.
Learn some basic conversational phrase
People in these three countries are friendly, and learning some basic local phrases like “Hello” or “Thank you” will help you connect more easily. So, how to say “Hello” in Vietnam, Laos, and Cambodia? It’s “Xin chào,” “Sabai Dee,” and “Suosay,” respectively. Even just a simple phrase will make the locals happy and willing to help you.

Don’t be afraid to try street food
Food is an important part of the journey. Enjoying pho and banh mi in Vietnam; laap in Laos; and amok in Cambodia will make your trip more interesting. We recommend you to try these foods in street stalls for authentic flavor.
Prepare for diverse weather
The climates in the three countries vary by region and season, so remember to pack appropriate clothes. Bring a light sun-protective shirt, a pair of comfortable walking shoes, and an umbrella or light raincoat in case of sudden rain. Don’t forget sunscreen and insect repellent to protect your health.
Slow down and enjoy the moment
While the 15-day journey may tempt you to rush to see more places, it’s important to savor each moment. Sitting by the Mekong River watching the sunset, chatting with locals, or simply strolling around the old town will help you feel more clearly the culture and pace of life here.
With the above tips, your holiday will not only be a sightseeing trip but also an opportunity to learn more about the culture and people of Indochina.
