You’ve got seven days off work and a burning desire to see Southeast Asia. The region is massive, but you can absolutely hit three incredible cities in one week if you plan smart.
A one week Southeast Asia itinerary covering Bangkok, Siem Reap, and Hanoi gives you temples, street food, and ancient history without feeling rushed. Spend two days in Bangkok, two exploring Angkor Wat, and three in Hanoi and Halong Bay. Budget flights between cities take under two hours. Expect to spend $800 to $1,200 per person including flights, mid-range hotels, and meals. Book temples and bay tours in advance during peak season.
Why These Three Cities Work Together
Bangkok, Siem Reap, and Hanoi form a natural triangle across Southeast Asia. They’re close enough that flights rarely exceed 90 minutes. Each city offers something distinct: Bangkok delivers urban energy and night markets, Siem Reap centers on Angkor Wat’s temple complex, and Hanoi provides French colonial charm mixed with Vietnamese street culture.
The logistics are straightforward. Budget airlines like AirAsia and VietJet run multiple daily flights between these hubs. Visa requirements are simple for most Western passport holders. Thailand offers visa-free entry for 30 days, Cambodia sells visas on arrival for $30, and Vietnam now offers e-visas you can arrange before departure.
One week means you’ll skip some places. You won’t see the beaches of southern Thailand or the rice terraces of northern Vietnam. But you’ll get a solid introduction to three distinct Southeast Asian cultures without spending half your vacation in airports.
Day-by-Day Breakdown
Days 1-2: Bangkok
Land in Bangkok early morning if possible. Most long-haul flights from North America or Europe arrive around dawn, which works perfectly.
Day one should focus on the historic center. Start at the Grand Palace before 9am to beat tour groups. The complex takes two hours minimum. Wat Pho sits next door and houses the famous reclining Buddha. Both require covered shoulders and long pants.
Grab lunch in the old town, then take a ferry up the Chao Phraya River to Wat Arun. The climb up the central tower offers views across the river. Head back downtown by late afternoon.
Bangkok’s night markets are essential. Rot Fai Market in Ratchada operates Thursday through Sunday and combines vintage shopping with excellent street food. If you’re there midweek, hit Asiatique by the river instead.
Day two lets you choose your own adventure. Options include:
- Chatuchak Weekend Market (Saturday and Sunday only, 15,000+ stalls)
- Jim Thompson House for Thai architecture and silk history
- Chinatown’s Yaowarat Road for gold shops and seafood restaurants
- A cooking class in a local neighborhood
- Day trip to Ayutthaya’s temple ruins (90 minutes north)
Book an evening flight to Siem Reap. You’ll arrive around 8pm, check into your hotel, and rest up for temple touring.
Days 3-4: Siem Reap and Angkor Wat
Angkor Wat demands an early start. Most visitors aim for sunrise, which means leaving your hotel by 5am. The temple complex covers over 150 square miles. You need a strategy.
Here’s a practical two-day temple route:
Day Three:
1. Angkor Wat at sunrise (arrive by 5:30am)
2. Breakfast break at your hotel (7:30-9am)
3. Angkor Thom and Bayon Temple (9am-12pm)
4. Lunch in Siem Reap town (12-2pm)
5. Ta Prohm temple with tree roots (2-4pm)
6. Sunset at Pre Rup or Phnom Bakheng (5-6:30pm)
Day Four:
1. Banteay Srei, the “pink temple” (7-9am, 45 minutes from town)
2. Banteay Samre on the way back (9:30-10:30am)
3. Hotel pool break during midday heat (11am-3pm)
4. Explore Siem Reap’s Old Market and Pub Street (3-7pm)
5. Apsara dance dinner show (7:30pm)
You’ll need a multi-day Angkor pass. The three-day pass costs $62 and works well even if you only use two days. Hire a tuk-tuk driver for both days. Negotiate $25-30 per day including all stops. Bring sunscreen, a hat, and at least two liters of water per person.
Fly to Hanoi on the evening of day four. Vietnam Airlines and VietJet both run this route. You’ll land around 10pm.
Days 5-7: Hanoi and Halong Bay
Hanoi’s Old Quarter is walkable and packed into about one square mile. Day five should be a recovery day after temple touring.
Sleep in, then spend the afternoon wandering the 36 streets of the Old Quarter. Each street traditionally sold one product: silk, silver, paper goods. Stop at Hoan Kiem Lake in the center. The red bridge leads to Ngoc Son Temple on a small island.
Try these Hanoi essentials:
- Bun cha (grilled pork with noodles, Obama ate it here in 2016)
- Egg coffee at Cafe Giang (hidden down an alley)
- Banh mi from street carts (30 cents to $1)
- Bia hoi (fresh beer served on tiny plastic stools)
Book a Halong Bay tour for days six and seven. Overnight cruises work better than day trips. You’ll board around noon on day six, sail through limestone karsts, kayak in hidden lagoons, and sleep on the boat. Day seven includes a morning cave tour before returning to Hanoi by 4pm.
If you skip Halong Bay, use day six for a day trip to Ninh Binh (two hours south) or spend it visiting Hanoi’s museums: the Ethnology Museum covers Vietnam’s 54 ethnic groups, and the Hoa Lo Prison tells the story of French colonial rule and the Vietnam War.
Your flight home likely leaves early morning on day eight, so keep day seven light. Do last-minute shopping in the Old Quarter and pack.
Practical Planning Details
Flights Between Cities
| Route | Airlines | Flight Time | Typical Cost |
|---|---|---|---|
| Bangkok to Siem Reap | Bangkok Airways, AirAsia | 1 hour | $60-120 |
| Siem Reap to Hanoi | Vietnam Airlines, VietJet | 2 hours | $80-150 |
| Hanoi to Bangkok | Multiple carriers | 2 hours | $70-140 |
Book flights at least six weeks out. Prices jump during December, January, and Chinese New Year. Tuesday and Wednesday flights cost less than weekend departures.
Accommodation Strategy
Stay central in all three cities. You’ll waste time commuting from cheap suburbs.
Bangkok: Choose between Sukhumvit for modern hotels and nightlife, or Rattanakosin for proximity to temples. Budget $40-80 per night for comfortable three-star hotels.
Siem Reap: Stay within walking distance of Pub Street. Hotels here are cheaper than Bangkok. Expect $30-60 per night for similar quality.
Hanoi: The Old Quarter puts you in the center of the action but rooms are small. Budget $35-70 per night.
Book hotels with free cancellation. Plans change when you’re moving this fast.
Money and Budgets
Thailand uses baht (35-36 per USD), Cambodia uses both riel and US dollars, Vietnam uses dong (24,000-25,000 per USD). ATMs are everywhere. Notify your bank before you leave.
Daily budget breakdown per person:
- Budget traveler: $50-70 (hostels, street food, public transport)
- Mid-range traveler: $100-140 (three-star hotels, mix of restaurants, private drivers)
- Comfort traveler: $180-250 (four-star hotels, nicer restaurants, guided tours)
These numbers exclude international flights and inter-city flights.
What to Pack
You need less than you think. One week fits in a carry-on if you pack smart.
Essential items:
– Lightweight long pants and shirts with sleeves (temple dress codes)
– Comfortable walking shoes (you’ll log 15,000+ steps daily)
– Sunscreen and hat (tropical sun is intense)
– Power adapter (Type A, B, and C plugs across the region)
– Copies of your passport (leave originals in hotel safes)
– Basic first aid kit with anti-diarrheal medication
Leave fancy jewelry at home. Bring one credit card and one debit card, stored separately.
Common Mistakes to Avoid
First-time Southeast Asia travelers make predictable errors. Here’s what to watch for:
| Mistake | Why It Hurts | Better Approach |
|---|---|---|
| Booking noon flights | Wastes half a day in transit | Take earliest morning flights |
| Skipping travel insurance | Medical evacuation costs thousands | Buy coverage before you leave |
| Changing money at airports | Rates are 10-15% worse | Use ATMs in the city center |
| Over-scheduling temples | Leads to burnout and blurry memories | Pick 5-6 temples max in Siem Reap |
| Eating only at tourist restaurants | Miss authentic flavors, pay triple | Eat where locals eat |
Temple fatigue is real. After four or five temples, they start blending together. Quality beats quantity.
Timing Your Trip
Southeast Asia has two seasons: hot and wet, or hot and dry. The dry season runs November through March. This is peak tourist season. Temples get crowded, hotels cost more, but you’ll have clear skies.
April and May are brutally hot. Temperatures hit 95-100°F with high humidity. June through October brings monsoon rains. Afternoon downpours are common but usually last only an hour or two.
The sweet spot is November or February. Weather is pleasant, crowds are manageable, and prices haven’t peaked yet.
“Don’t try to see everything. Southeast Asia rewards slow travel, but if you only have a week, accept that you’re getting a sampler. Go deep in a few places rather than collecting passport stamps.” — Longtime expat living in Bangkok
Food Safety and Health
Street food is generally safe if you follow basic rules. Eat at busy stalls with high turnover. Watch for food sitting out in the heat. Avoid ice in rural areas but it’s fine in cities.
Bring anti-diarrheal medication anyway. Most travelers get mild stomach issues from the change in food and water. It’s rarely serious.
Get vaccinated before you go. Standard recommendations include Hepatitis A, Typhoid, and a Tetanus booster. Malaria isn’t a concern in these three cities. Check the CDC website for current guidance.
Drink bottled water. Brush your teeth with bottled water too. A case of 12 bottles costs about $2 at any convenience store.
Getting Around Each City
Bangkok: Use the BTS Skytrain and MRT subway for major destinations. Grab (Southeast Asia’s Uber) works perfectly for everything else. Avoid taxis unless they use the meter.
Siem Reap: Hire a tuk-tuk driver for temple days. Walk or rent a bicycle for town. The city is small and flat.
Hanoi: Walk the Old Quarter. Use Grab for longer distances. Crossing streets looks terrifying but follow locals and move at a steady pace. Traffic flows around you.
Extending to Eight or Nine Days
If you can squeeze out an extra day or two, here’s where to add them:
Add one day to Bangkok for a floating market trip or a day in Ayutthaya. Add one day to Siem Reap to see the outer temples like Beng Mealea. Add one day to Hanoi for a cooking class and cyclo tour.
The three-city structure still works. You’ll just feel less rushed.
Booking Tours in Advance
Most activities can be booked after you arrive, but three things should be arranged ahead:
- Halong Bay overnight cruise (books up 2-3 weeks in advance during peak season)
- Cooking classes in any city (popular ones fill early)
- Apsara dance dinner shows in Siem Reap (not essential but convenient)
Everything else, book locally or through your hotel. You’ll often get better prices and more flexibility.
Making Your Week Count
Seven days isn’t long, but it’s enough to fall in love with Southeast Asia. You’ll taste incredible food, meet welcoming people, and see some of humanity’s most impressive architecture.
The key is accepting what this trip is and isn’t. You’re not becoming a Southeast Asia expert in one week. You’re testing whether you want to come back. Most people do.
Move with intention. Wake up early. Eat the street food. Talk to your tuk-tuk drivers. Take fewer photos and spend more time actually looking at what’s in front of you. One week goes fast, but the memories stick around much longer.
