5-Week Southeast Asia Itinerary: 3 Options 2025)

With 5 weeks in Southeast Asia, you could either visit the highlights of 4–5 countries or delve deeply into the most representative three countries.

In this article, we introduce three hand-picked itineraries based on the most popular destinations of Southeast Asia. They are fully-customizable and have been welcomed by our clients as the basis for many a tour. These suggestions will help you optimize your time and create your dream trip.

Which Countries Would Be Best for Your 5-Week SE Asia Trip?

When planning a 5-week trip to Southeast Asia, you're suggested to limit your travels to 3–5 countries to save costs in transportation and to avoid travel fatigue.

If you want a more relaxing tour pace, focus on three countries: Thailand, Cambodia, and Vietnam are recommended. They are the top combo among all the popular itineraries for Southeast Asia, particularly for first-timers. Meanwhile, with five weeks you could have many more in-depth travel experiences.

If you would prefer to use your time to travel more widely, you could combine the above three with two other countries for a wider variety of experiences: Myanmar-Laos or Singapore-Bali. Myanmar and Laos are more recommended for people who are keen on in-depth cultural experiences, while Singapore and Indonesia (Bali) are best for leisurely relaxation opportunities.

Below are the countries recommended above with their recommended travel durations and destination areas.

• Thailand: 8 days to 3 weeks. Bangkok, Chiang Mai, and islands like Phuket and Koh Samui are the top highlights.
• Vietnam: 10 days to 2 weeks. Hanoi, Ha Long Bay, Hoi An, Ho Chi Min City, and the Mekong Delta are must-sees.
• Myanmar: 1–2 weeks. Mandalay, Bagan, and Yangon are three of its best destinations.
• Cambodia: 3 days to 1 week. Siem Reap, home to Angkor Wat, tops the bucket list for most Cambodia trips.
• Laos: 1 week. Luang Prabang is the main tourist city.
• Singapore (3 days) and Bali (7–10 days) usually work as a unique pair: rich culinary experiences and shopping paradise in Singapore plus laid-back island exploring in Bali.

1. A Classic 5-Week Grand Indochina Tour: Thailand, Cambodia, Vietnam, Myanmar, and Laos

This tour shows you the multiple facets of Southeast Asia at a comfortable pace. Besides the most-popular Thailand, Vietnam, and Cambodia, you'd explore Southeast Asia beyond the beaten path in Myanmar and Laos.

With us, you'd not only see the iconic attractions in each country but also have the chance to explore their cultures deeper with our exclusive experiences.

Check out this brief itinerary and description for inspiration:

8 Days in Myanmar

• Days 1–2 in Mandalay (city tour with temples, witness thousands of monks dining, watch the sunset over U Bein Bridge)
• Days 3–4 in Bagan (underground monastery, local markets, and sunset balloon ride over 2,000 pagodas)
• Days 5–6 at Inle Lake (floating villages, floating markets, stunning lake view, and traditional fishing)
• Days 7–8 in Yangon (an interesting local train ride, museums, and Shwedagon Pagoda at sunset)

In Myanmar, temples and pagodas are the top highlights, while Inle Lake presents rustic and authentic floating village life for you to discover. Bagan is best for romantic celebrations, milestone trips in particular. What could be more romantic than holding your partner and seeing the sun set over 2,000 pagodas from a hot air balloon?

10 Days in Vietnam

• Days 9–10 in Ho Chi Minh City (city tour with coffee experience, the Cu Chi Tunnels)
• Days 11–13 in Hoi An (lantern-making, sunset boat ride, an evening foodie tour, plus a free day)
• Days 14–15 in Hanoi (Old Quarter walking tour, museums, water puppet show)
• Days 16–18 in Ha Long Bay (Trung Trang Cave, squid fishing, cooking class, biking around a rustic village near Ha Long Bay)

In Vietnam, Ho Chi Minh City presents bustling modern city life and tragic war history in the Cu Chi Tunnels. Hoi An balances old town architecture with laid-back rustic life.

A Ha Long Bay cruise is a perfect combo of outdoor fun and laid-back activities. We suggest a 3-day cruise to escape the big tour groups and enjoy kayaking, swimming, and tranquil private hours in the unspoiled and less-visited coves. Want more private experiences? Contact us for a private junk just for the two of you.

4 Days in Laos

• Days 19–22 in Luang Prabang (offering alms to monks in the early morning, temples, Royal Palace, waterfall, sunset long-tail boat ride)

Featuring serenity, Luang Prabang is an ideal place to refresh after 2 weeks of travel. Don't miss the awe-inspiring traditional ritual: morning almsgiving. You and your partner could relax in your boutique hotel with swim-up pool rooms and quality massages during your free days.

3 Days in Cambodia

• Days 23–25 in Siem Reap (Angkor Wat, Apsara Dance Show, 1-hour sunset quad bike ride, sunset cocktail on Tonle Sap Lake)

In Siem Reap, Angkor Wat is the big draw. A sunset quad bike ride and sunset cocktail on Tonle Sap Lake would enhance your trip with special moments.

10 Days in Thailand

• Days 28–30 in Chiang Mai (foodie tour, flower market visit, elephant sanctuary)

In Thailand, one of the highlight areas is Chiang Mai. Your trip would not be complete without an elephant sanctuary and local flower market visits. Around November, you'd have chances to celebrate the 2-day Yi Peng Festival (November 5–6, 2025). Travel with us to have a premium experience (only sold by us): release your own lanterns into the sky and capture enchanting moments with thousands of floating lanterns.

This itinerary also includes the island of Phuket, which is easily accessible and rich in water activities. If you're looking for a more romantic vibe and private times, Koh Samui is suggested for more high-end boutique hotels and fine dining.

2. A 5-Week In-Depth Exploration with a Luxury Mekong River Cruise: Thailand–Cambodia–Vietnam

If you would prefer an in-depth experience at a slow pace, this itinerary is best for you. For first-timers, the classic combo of Thailand, Cambodia, and Vietnam perfectly shows you the best of Southeast Asia: awe-inspiring temples, rustic life, amazing food, as well as mesmerizing islands.

During your 5 weeks' travel, you'd explore the iconic sights, but also some offbeat areas, like Chiang Rai and the Mekong River.

Here is a brief summary of the itinerary for your inspiration:

10 Days in Vietnam

Without frequent hotel changes, you would conveniently indulge in the hidden beauty and rustic life along the Mekong. Our carefully-selected cruise just has just 14 rooms, so you'd be away from chaotic tour groups and could enjoy more quality time alone. See more details on our Mekong Cruise tour>>>

We have picked three islands for you: Phu Quoc Island for tranquil experiences, Phuket for various water activities, and Bali for artistic beauty, yoga, and culture.

During your 5 weeks' travel, you'd stay at various character-filled boutique hotels: elegant 1920s-style hotels, floating houses, jungle hotels, tree houses, and cliff hotels with infinity pools... all of them embrace tranquility and unique experiences, perfect for quality time alone.

Costs for a 5-Week Southeast Asia Tour

Compared with developed countries, a private tour in Southeast Asia is affordable, exclusive, and hassle-free — ideal for your milestone trip.

Usually, you would need around US$200–250 per day per person for quality 4/5-star hotels, nice meals, convenient transport, and private, tailored touring.

So, apart from the international flights from/to your country, you would need to spend around US$14,000–17,500 on a 5-week private trip for a couple.

Southeast Asia's prices depend on the seasons as well. You'd better prepare for the highest prices in the dry season (mostly November to April). The lowest costs arrive in the rainy season (mostly May to October), which typically brings short-lived 1–2-hour afternoon rainfall.

If you prefer to enjoy the best weather without exceeding your budget, consider inviting your friends or wider family to share costs and create unforgettable memories together.
