Vietnam Itinerary 3 Weeks: Complete North-South Guide 2026

A 21-day route offers a less demanding pace than a two-week trip: you spend 2 to 3 nights per stop instead of just one, you have time to get off the beaten path (villages around Sapa, less touristy Halong Bay islands, countryside around Hoi An), and you can add a destination that short routes sacrifice (Da Lat, Phu Quoc, or the Mekong Delta). If you're hesitating between 15 and 21 days, first read the 15-day Vietnam itinerary: that article explains what the third week concretely adds.

01What the third week adds compared to 15 days

A 15-day itinerary already covers the north (Hanoi, Halong, Ninh Binh or Sapa), the center (Hue, Hoi An, Da Nang) and the south (Ho Chi Minh City), but it imposes a sustained pace: one night per stop, overnight trips to save time, little margin to rest or improvise. With 21 days, you double the duration in at least two regions (for example 3 nights in Hanoi instead of one, 3 nights in Hoi An instead of two), you add a secondary destination (Da Lat, the Mekong Delta or Phu Quoc), and you finish with 3 to 4 beach days or a Cambodia extension (Angkor).

Concretely, the third week allows you to visit the Mekong Delta from Ho Chi Minh City (2 days), spend 3 nights in Phu Quoc to decompress, or replace Nha Trang with Da Lat if you prefer mountains to beach. It also offers time for long activities: 2-day trek in Sapa, cooking class in Hoi An, full-day excursion in the countryside around Ninh Binh. If you're traveling with children or if you don't like overnight trips, these 6 extra days make the trip much more comfortable.

02Day-by-day itinerary: north-south in 21 days

This table details a classic north-to-south route, with routes between stops, their durations and recommended modes of transport. Durations include actual travel time, not waiting times at airports or stations. Prices are orders of magnitude in VND and euros (1 € ≈ 27,000 VND) as of 10/11/2026, according to data from railway companies (Vietnam Railways), airlines (Vietnam Airlines, VietJet, Bamboo Airways) and bus companies (The Sinh Tourist, Futa Bus Lines) consulted in November 2026.

This route favors planes for long distances (Hanoi-Hue, Da Nang-Nha Trang, possibly Da Lat-HCMC) to save time. If you prefer trains, the Hue-Da Nang route is splendid (2h30, 100,000-200,000 VND), and the Hanoi-Hue night train exists (12-14h, 600,000-1,200,000 VND depending on class), but it extends the route. Sleeper buses are an economical option for Nha Trang-Da Lat or Da Lat-HCMC, but they often leave at night.

03Variant 1: replace Nha Trang with more time in Hoi An or Da Nang

Nha Trang is a very touristy seaside resort, with decent beaches but a Russian resort atmosphere: if you're looking for authenticity or if you've already planned Phu Quoc at the end of your route, you can skip Nha Trang and spend 4 nights in Hoi An (instead of 3) or 2 nights in Da Nang. Hoi An offers quieter beaches (An Bang, Cua Dai), cooking classes, bike rides in the countryside, and the old town is a UNESCO site. Da Nang, where I live, offers My Khe and Non Nuoc beaches, the Marble Mountains, Son Tra peninsula, and real local life away from tourist circuits: check what to do in Da Nang for concrete ideas.

If you remove Nha Trang, the Da Nang → Da Lat route is by night bus (12-14h, 300,000-500,000 VND) or by plane with a stopover in Ho Chi Minh City (1h + 1h, 1,500,000-2,500,000 VND). The simplest option is to go directly from Da Nang to Ho Chi Minh City by plane (1h20, 800,000-1,500,000 VND), then join Da Lat from HCMC by bus (7-8h, 250,000 VND) or by plane (50 min, 1,000,000 VND). This variant frees up 2 days that you can add to Hoi An, Da Nang, or the Mekong Delta.

04Variant 2: finish with 3-4 beach days in Phu Quoc

If you want to decompress at the end of your route, replace days 18-20 (Mekong Delta + HCMC) with 3 nights in Phu Quoc: you fly from Ho Chi Minh City to Phu Quoc on day 18 (1h, 800,000-1,500,000 VND), you spend 3 days on the island (beaches, snorkeling, night markets), and you return to HCMC on day 21 for your international flight (1h, 800,000-1,500,000 VND). Phu Quoc offers white sand beaches (Long Beach, Sao Beach), fishing villages (Ham Ninh, Rach Vem), and a calmer atmosphere than Nha Trang, even if real estate development is accelerating: read Phu Quoc island to know when to go and what to do.

This variant is suitable if you're traveling with family or if you want a less sustained pace at the end of your route. Disadvantage: you sacrifice the Mekong Delta, which is nevertheless a unique region (floating markets, orchards, life on water). An intermediate solution is to do a one-day excursion in the delta from Ho Chi Minh City (departure 7am, return 6pm, 600,000-1,000,000 VND with agency), then fly to Phu Quoc the next day for 2 nights instead of 3.

05Variant 3: Cambodia extension (Angkor) instead of Phu Quoc

If you've already visited Vietnam's beaches or if you prefer temples to beaches, replace Phu Quoc with 3-4 days in Siem Reap (Angkor): you take a bus from Ho Chi Minh City to Phnom Penh (6h, 300,000-500,000 VND), then a bus from Phnom Penh to Siem Reap (6h, 300,000-400,000 VND), or you fly directly from HCMC to Siem Reap (1h, 1,500,000-2,500,000 VND). You spend 2-3 days at Angkor (temples of Angkor Wat, Bayon, Ta Prohm), then you return to HCMC or you fly directly from Siem Reap to your country (international flights from Siem Reap).

This extension requires a Cambodian visa (e-visa 36 USD on evisa.gov.kh, visa on arrival 30 USD + 6 USD fees, or land visa 30 USD at the border): plan for an ID photo and 30-40 USD in cash. The Moc Bai (Vietnam) / Bavet (Cambodia) land border crossing is the busiest from Ho Chi Minh City; allow 1h-2h for formalities. If you choose this variant, verify that your Vietnamese visa authorizes multiple entries if you return to Vietnam after Cambodia (Vietnamese multiple-entry e-visa, 50 USD, valid 90 days, on evisa.gov.vn).

06Routes between stops: train, plane, bus

Vietnam has a north-south railway network (Reunification Express, Hanoi-Ho Chi Minh City in 30-36h), frequent domestic flights (Vietnam Airlines, VietJet, Bamboo Airways) and reliable bus companies (The Sinh Tourist, Futa Bus Lines, Phuong Trang). For a 3-week route, combine the three modes according to distances: train for Hue-Da Nang (2h30, coastal landscapes), plane for Hanoi-Hue or Da Nang-Nha Trang (1h-1h30, time saving), bus for short routes (Hoi An-Da Nang, HCMC-Mekong Delta) or connections without train or direct flight (Nha Trang-Da Lat, Da Lat-HCMC).

Domestic flights are booked on company websites or via comparators (Skyscanner, Google Flights): book 2-4 weeks in advance to get the best prices (800,000-1,500,000 VND per flight). Trains are booked on the official Vietnam Railways website or via agencies (Baolau, 12Go): soft sleepers (4 berths per cabin) cost 600,000-1,200,000 VND for Hanoi-Hue, hard seats 300,000-500,000 VND. Buses are booked online (company websites, 12Go, Baolau) or directly at bus stations: sleeper buses are comfortable for night trips (reclining berths, air conditioning), regular buses for day trips.

For the Hanoi-Hue route, three options: plane (1h45, 1,500,000-2,500,000 VND), night train (12-14h, 600,000-1,200,000 VND), or night bus (14-16h, 400,000-600,000 VND). The plane is the fastest and often the most expensive, but prices drop if you book early or if you travel in low season (May-September). The night train is an experience in itself (landscapes, encounters), but it leaves in late afternoon and arrives early morning: you lose an evening in Hanoi and a morning in Hue. The night bus is the economical option, but less comfortable than the train.

07North: Hanoi, Halong, Ninh Binh (6 days)

Northern Vietnam concentrates iconic sites: Hanoi's old quarter, Halong Bay (one or two-night cruise), and terrestrial Halong Bay (Ninh Binh). With 6 days, you spend 3 nights in Hanoi (arrival + 2 full days), 1 night on a Halong cruise, and 2 nights in Ninh Binh. If you want to add Sapa (terraced rice fields, ethnic villages), replace Ninh Binh with 2-3 nights in Sapa (night train Hanoi-Lao Cai 8h, then bus or taxi 1h to Sapa), but you sacrifice Ninh Binh: both sites are magnificent, but Ninh Binh is closer to Hanoi (2h by bus) and can be visited in 1-2 days, while Sapa requires 3 days minimum (trekking, villages).

In Hanoi, visit the old quarter (36 guild streets), Hoan Kiem Lake, the Temple of Literature, Ho Chi Minh Mausoleum, and taste bun cha, pho and egg coffee: check what to do in Hanoi for a 2-3 day itinerary. The Halong cruise is booked in advance (1 night 80-150 USD, 2 nights 150-300 USD depending on boat): choose a mid-range boat (3 stars) to avoid crowded boats and scams, and favor routes to Bai Tu Long or Lan Ha, less touristy than classic Halong Bay. Read Halong Bay to compare options.

In Ninh Binh, visit Tam Coc (boat ride through rice fields), Trang An (caves and karst landscapes, UNESCO listed), Bai Dinh pagoda (the largest in Vietnam), and Phat Diem cathedral. Two days are enough to see the essentials: rent a bike or motorbike to explore the countryside, and sleep in Tam Coc or Ninh Binh city. The site is less spectacular than Halong but more authentic, with fewer tourists and magnificent rice field landscapes in May-June (transplanting) and September-October (harvest). Check terrestrial Halong Bay for practical details.

08Center: Hue, Hoi An, Da Nang (6 days)

Central Vietnam offers a mix of culture (Hue Imperial City, Hoi An old town), beaches (Da Nang, Hoi An) and landscapes (Hai Van Pass, Marble Mountains). With 6 days, you spend 2 nights in Hue, 3 nights in Hoi An, and 1 night in Da Nang. If you prefer beach to culture, spend 2 nights in Hue and 4 nights in Hoi An (or 3 in Hoi An + 2 in Da Nang). The Hue-Da Nang train route follows the coast and crosses Hai Van Pass: it's one of the most beautiful train routes in Vietnam, to be done during the day (departure Hue 7am or 1pm, arrival Da Nang 9:30am or 3:30pm).

In Hue, visit the Imperial City (palaces, temples, gardens), the emperors' tombs (Minh Mang, Khai Dinh, Tu Duc), Thien Mu pagoda, and taste bun bo Hue (spicy noodle soup). Two days are enough to see the essentials: rent a scooter or take a taxi for the tombs (10-15 km from center). In Hoi An, stroll through the old town (Japanese bridge, ancient houses, lanterns), visit An Bang and Cua Dai beaches, take a cooking class, and have clothes tailored (24-48h delay). Three nights allow you to visit the old town, spend a day at the beach, and do a bike excursion in the countryside (rice fields, villages, islands). Read visiting Hoi An for details.

In Da Nang, visit the Marble Mountains (caves, pagodas, panoramic view), My Khe beach (one of Vietnam's most beautiful), Cham Museum (sculptures), and Son Tra peninsula (Linh Ung pagoda, monkeys). One day is enough to see the essentials if you arrive from Hoi An in the morning and leave the next day. Da Nang is a modern city, less touristy than Hoi An, with good seafood restaurants and active nightlife (bars, clubs): if you like lively cities, spend 2 nights instead of one. The Hoi An-Da Nang route is by bus (30-45 min, 50,000-100,000 VND), taxi (30 min, 300,000-400,000 VND) or Grab (20-30 min, 150,000-200,000 VND): check getting from Da Nang to Hoi An for all options.

09South: Nha Trang, Da Lat, Ho Chi Minh City, Mekong Delta (9 days)

Southern Vietnam combines beaches (Nha Trang), mountains (Da Lat), megacity (Ho Chi Minh City) and aquatic countryside (Mekong Delta). With 9 days, you spend 2 nights in Nha Trang, 2 nights in Da Lat, 3 nights in Ho Chi Minh City (including 1 in the delta), and you keep 2 days margin for Phu Quoc or a Cambodia extension. If you skip Nha Trang (see variant 1), you gain 2 days that you can add to Da Lat (trekking, waterfalls, coffee plantations) or the Mekong Delta (2 nights instead of one, to explore floating markets and orchards).

In Nha Trang, enjoy the beaches (Nha Trang Beach, Bai Dai), go snorkeling or diving (Hon Mun, Hon Tam islands), visit Po Nagar Cham towers, and taste seafood at Dam market. Two days are enough: Nha Trang is a highly developed seaside resort, with many Russian and Chinese resorts, less authentic than Hoi An or Phu Quoc. In Da Lat, visit waterfalls (Datanla, Pongour), coffee and flower plantations, Xuan Huong Lake, Da Lat station (French colonial architecture), and ethnic villages around the city. Da Lat is a mountain city (1,500 m altitude), with a cool climate (15-25°C) and landscapes of pines and hills: it's the ideal destination if you're tired of the heat and humidity of the coast. Check Da Lat to know when to go and what to do.

In Ho Chi Minh City, visit the Reunification Palace, Notre-Dame Cathedral, Central Post Office (colonial architecture), Ben Thanh market, Cholon Chinese quarter, and Cu Chi tunnels (40 km from the city, half-day excursion). Two full days are enough to see the essentials: HCMC is a megacity of 9 million inhabitants, noisy and polluted, but dynamic and fascinating. Read what to do in Ho Chi Minh City for a 2-3 day itinerary. In the Mekong Delta, visit Cai Rang floating markets (near Can Tho, boat departure 5am-6am), tropical fruit orchards, coconut candy factories, and stilt villages. One night in Can Tho allows you to see the floating market at dawn, then return to HCMC in the afternoon: check southern Vietnam for practical details.

10Transport budget for 3 weeks

The transport budget for a 3-week route in Vietnam depends on your choices (plane or train, bus or taxi, economical or luxury Halong cruise). Here's a realistic estimate for a solo traveler, excluding international flight, as of 10/11/2026 (rates consulted on company websites):

• Domestic flights (Hanoi-Hue, Da Nang-Nha Trang, HCMC-Phu Quoc if applicable): 3,000,000-5,000,000 VND (111-185 €)
• Trains (Hue-Da Nang, possibly Hanoi-Hue in sleeper): 200,000-1,500,000 VND (7-56 €)
• Long-distance buses (Ninh Binh-Hanoi, Nha Trang-Da Lat, Da Lat-HCMC, HCMC-Can Tho): 800,000-1,500,000 VND (30-56 €)
• Local transfers (taxi, Grab, local buses): 1,000,000-2,000,000 VND (37-74 €)
• Halong cruise (1 night): 2,000,000-4,000,000 VND (74-148 €)

Total transport: 7,000,000-14,000,000 VND (260-520 €) for 3 weeks, or 330,000-670,000 VND (12-25 €) per day. If you take all flights in economy class and book early, count 10,000,000-12,000,000 VND (370-445 €). If you favor train and bus, count 7,000,000-9,000,000 VND (260-335 €). These amounts don't include the France-Vietnam international flight (700-1,200 € round trip depending on season): check France-Vietnam plane ticket for tips.

The total budget for a 3-week trip (excluding international flight) varies from 20,000,000 VND (740 €) in backpacker mode (hostels, street food, buses) to 60,000,000 VND (2,220 €) in comfort mode (3-4 star hotels, restaurants, planes). Check Vietnam travel budget for a detailed estimate by category (accommodation, meals, activities, transport).

11Best time for 3 weeks in Vietnam

Vietnam stretches 1,650 km from north to south, with three climate zones: the north (Hanoi, Halong) has a cool and humid winter (December-February, 15-20°C) and a hot and humid summer (June-August, 30-35°C); the center (Hue, Hoi An, Da Nang) suffers from autumn monsoon (September-December, rain and typhoons); the south (Ho Chi Minh City, Mekong Delta) has two seasons, dry (November-April) and humid (May-October). For a north-to-south route, the best time is February-April (spring in the north, dry in center and south, pleasant temperatures everywhere) or November-early December (end of monsoon in center, start of dry season in south, mild temperatures in north).

Avoid September-October (monsoon in center, heavy rains and typhoon risk in Hue, Hoi An, Da Nang) and July-August (very hot and humid everywhere, high tourist season, high prices). If you travel in July-August, favor the north (Hanoi, Sapa) and south (HCMC, Phu Quoc), and spend less time in the center. If you travel in September-November, do the route south-north to avoid the monsoon in the center at the start of your trip. Check best time to go to Vietnam for a month-by-month guide.

12Formalities: visa, passport, insurance

French citizens benefit from a 45-day single-entry visa exemption (as of 10/11/2026), sufficient for a 3-week route. If you're planning a Cambodia extension with return to Vietnam, or if you want to keep a safety margin, apply for a Vietnamese multiple-entry e-visa (50 USD, valid 90 days, issued in 3 working days) on the official evisa.gov.vn site. Your passport must be valid at least 6 months after your Vietnam entry date and have at least 2 blank pages, according to recommendations from the French Ministry of Foreign Affairs. Check Vietnam visa for French citizens for details.

Entry rules depend on your nationality; the official portal is evisa.gov.vn. If you prefer someone to handle the application, visa-vietnam.app can do it. visa-vietnam.app is run by the same publisher as this site.

Take out travel insurance that covers medical expenses (hospitalization, repatriation), theft and loss of luggage, and trip cancellation: credit card insurance (Visa Premier, Mastercard Gold) covers trips under 90 days, but check limits and exclusions. Specific travel insurance (Chapka, AVI, Heymondo) costs 30-60 € for 3 weeks and offers more comprehensive guarantees. If you're traveling with children, verify that insurance covers the whole family.

13What to remember

Three weeks in Vietnam allow you to discover the country from north to south at a comfortable pace: you double the duration in each region compared to a 15-day route, you add a secondary destination (Da Lat, Mekong Delta, Phu Quoc), and you finish with 3-4 beach days or a Cambodia extension. The classic route covers Hanoi, Halong, Ninh Binh, Hue, Hoi An, Da Nang, Nha Trang (or Da Lat), Ho Chi Minh City and the Mekong Delta, with routes by train, plane and bus. Favor planes for long distances (Hanoi-Hue, Da Nang-Nha Trang) and trains for short and scenic routes (Hue-Da Nang).

The best time is February-April or November-early December, to avoid the monsoon in the center and summer heat. The transport budget varies from 260 to 520 € for 3 weeks, depending on your choices (plane or bus, economical or luxury cruise). Next step: book your domestic flights 2-4 weeks in advance to get the best prices, and check Vietnam travel to prepare your stay (accommodation, health, what to pack).
