The short answer
Three weeks lets you travel Vietnam from north to south with at least two nights almost everywhere. Our guides would choose Hanoi, two nights in Ninh Binh, two nights on Lan Ha Bay, Hue, four nights in Hoi An, three nights on the coast near Nha Trang, then Ho Chi Minh City with a night in the Mekong Delta.

With three weeks in Vietnam, the question changes. It is no longer what you can squeeze in, but where you would like to stay a little longer. Our guide team builds this route from the same backbone as our 14-day north-to-south tour, then adds the places a fortnight has to leave out: Ninh Binh, a second night on the bay, a fourth night in Hoi An, a few days on the beach and a night in the Mekong Delta.
Our 30-day nature and culture tour goes further still; we borrowed several of its slower stops.
Three weeks in Vietnam: the shape of the slow route
The route has eight bases, and every one except Can Tho gets at least two nights. That is the whole idea. Each region gets at least one afternoon with nothing fixed.
- North (7 nights): Hanoi, the karst country of Ninh Binh and two nights on Lan Ha Bay.
- Centre (10 nights): Hue, Hoi An and three nights on the coast.
- South (3 nights): Ho Chi Minh City and the Mekong Delta, with a night in Can Tho.
With less time, see our two-week north-to-south route; for ten days, our first-visit route.

What the extra week buys you
Ninh Binh at its own pace
Many trips see Ninh Binh in a day from Hanoi, about 95 kilometres away. Two nights let you take the Trang An boats in the afternoon and still wake up in the countryside, with time to walk or cycle before visiting the Bai Dinh complex.
Two nights on the bay
With one night, almost half the cruise goes on boarding and disembarking. With two, you have a full day on the water, and on the last morning we go straight from the marina to Hanoi airport for the flight to Hue. Our guide to choosing a Ha Long or Lan Ha Bay cruise compares ships.
Four nights in Hoi An
Hoi An rewards slow travel more than anywhere else in Vietnam. Four nights cover the old town at dawn, My Son, a cooking class and a day on the Cham Islands without two big outings on the same day.
A real beach break
Three nights on the coast split the trip into two halves and give everyone a real rest. The quickest way is a flight from Da Nang to Cam Ranh. The gentler way, for those who enjoy the journey, is The Vietage, a single luxury carriage on the coastal train with six private booths for twelve guests: about six hours from Da Nang to Quy Nhon, then about five to Nha Trang. Seats must be reserved at least three days ahead, and we usually break the journey with a night or two in between.
A night in the Delta
Staying in Can Tho means reaching the Cai Rang floating market early in the morning by boat, rather than after a long drive from the city.
Where to stay on a three-week route
Hanoi. Fairmont Hanoi opened in February 2026 a short walk from Hoan Kiem Lake, with 241 rooms and suites and a wellness floor with a bathhouse and a 20-metre lap pool.
Ninh Binh. We use Pullman Ninh Binh as our base here; your quote confirms the room type.
Lan Ha Bay. Heritage Line Ylang is the ship we have in mind for this route: two nights, at most 20 guests in ten suites of 40 to 54 square metres with private balconies, a spa, and tai chi and meditation on deck. It is the ship we most often pair with Ninh Binh on slower trips. For families, Capella Cruise also runs two-night programs, with family suites for five and a rooftop pool.
Hue, Ho Chi Minh City and Can Tho. We choose a central 4–5★ hotel in each and name it in your quote.
Hoi An. Four Seasons Resort The Nam Hai is the easiest base for mixing beach days with Hoi An and My Son, with 100 villas on a kilometre of Ha My beach. NHAAN Resort & Spa Hoi An, in Cam Thanh village by the Co Co River, runs workshops in pottery, lantern-making and woodcarving. Hotel Royal Hoi An – MGallery sits on the Thu Bon River, a short walk from the old town.
The coast. L’Alya Ninh Van Bay suits couples who want a lagoon villa near Nha Trang. Amanoi, inside Nui Chua National Park above Vinh Hy Bay and about 75 minutes from Cam Ranh airport, is for guests who want quiet, good food and a serious spa. If you take The Vietage, Zannier Hotels Bãi San Hô, with 73 villas on a private coral bay at Song Cau, can break the journey down the coast; we confirm the transfer in your quote.
More choices are in our guide to where to stay in Vietnam at 4–5★.
What three weeks in Vietnam costs
Private Vietnam trips start from 140 USD per person per day, based on two travellers sharing, 4★ hotels and a private guide and driver throughout, confirmed in your private quote. As a worked example, 21 days at 140 USD gives from 2,940 USD per person.
A group of four saves 5%, bringing the from-price to 133 USD per person per day; a group of six saves 8%, about 129 USD. Nights at 5★ luxury resorts such as Amanoi, Zannier or The Nam Hai, move that part of the trip to our top tier, from 350 USD per person per day, quoted individually. The Vietage is priced in your private quote.
Domestic flights are quoted separately; this route uses three, Hanoi to Hue, Da Nang to Cam Ranh and Cam Ranh to Ho Chi Minh City. Bookings are confirmed with a 30% deposit, with the balance due 45 days before arrival, plus a non-refundable holding fee of 100 USD per traveller, separate from the deposit. Card payments carry a 3.5% fee.

Slow-travel tips from our guides
Choosing your season
A three-week route meets every Vietnamese climate. According to Vietnam’s national tourism site, Hanoi and Ha Long are cool and often misty from December to March and warm with clear skies from April to June. Hue is dry from March to August and rainy from September to February, with flooding possible from September to November. Nha Trang is rainy from September to December, and Ho Chi Minh City is dry from December to April. March and April are the months when the whole route is most likely to be dry and warm; our month-by-month guide explains the trade-offs.
Health on a longer trip
The US CDC advises being up to date on routine vaccines, recommends hepatitis A and typhoid vaccines for most travellers to Vietnam, and advises preventing mosquito bites. Bring enough regular medication for the whole trip plus a few days, keep it in hand luggage with a copy of the prescription, and buy travel insurance that covers medical evacuation. More in our advice on Vietnam for older travellers.
Rest days are part of the plan
Our guides treat free afternoons as fixed appointments: a nap or a long lunch on day ten is what makes day eighteen enjoyable. Tell us about knees, stairs or heat early, and we will adjust walks and boat boardings.
Teenagers on a long trip
Give teenagers variety: the Trang An boats, cycling in Viet Hai village, kayaking, a lantern workshop in Hoi An and snorkelling on the coast.
Lighter footprint
Slow travel is lower-impact travel: fewer flights per week and longer stays with local businesses. Carry a refillable bottle, buy crafts from the makers, and ask before photographing people.
Visas
Entry rules depend on your passport. Vietnam’s e-visa, applied for through the government portal, can be valid for up to 90 days, which covers a three-week trip; check your own case before booking flights.
Metta Voyage has looked after more than 10,100 travellers across 2,000+ bookings; tell us how you like to travel and we will set the pace with you.

Questions we are often asked
Is three weeks too long for Vietnam?
No. Three weeks lets you add Ninh Binh, a second night on the bay, a beach break and the Mekong Delta to the classic route, with rest days built in.
Which beach fits best into a three-week route?
The coast around Nha Trang and Cam Ranh sits between the centre and the south, so it splits the trip neatly. We use L'Alya Ninh Van Bay or Amanoi, or Zannier Bãi San Hô if you travel by The Vietage.
How many domestic flights does the slow route need?
Three: Hanoi to Hue, Da Nang to Cam Ranh and Cam Ranh to Ho Chi Minh City. Domestic flights are quoted separately.
When is the best time for a three-week trip?
March and April usually suit the whole route, because the centre and south are in their dry season and the north is warming up. We can adjust the order for other months.
Can we replace a flight with a train?
Yes. The Vietage runs daily from Da Nang to Quy Nhon and from Quy Nhon to Nha Trang; seats must be reserved at least three days ahead.
