Vietnam Itinerary for 14 Days, North to South (2026): Where You Need Data and How You Pay at Each Stop

Hanoi, Ha Long Bay, Da Nang and Hoi An, Nha Trang, Saigon: a 14-day north-to-south route with a 10-day cut, flights for the long legs, and for each stop what data you need and how you pay.

Quick answer: As of 2 November 2026, a practical Vietnam itinerary for 14 days runs north to south: Hanoi (3 days), Ha Long Bay (2), Da Nang and Hoi An (4), Nha Trang (2) and Saigon (3), flying the long legs because the Reunification Express takes about 33 to 41 hours from Hanoi to Saigon. One travel eSIM installed before you fly covers the whole route; the places you will most want data are the arrival hall, the ride app and the quiet stretches, and the places you will want cash are the margins.

Key takeaways

Route: Hanoi 3 days, Ha Long Bay 2, Da Nang and Hoi An 4, Nha Trang 2, Saigon 3. Drop Nha Trang for 10 days.
Fly the long legs. A timetable page checked on 21 October 2026 lists 33 to 41 hours by train from Hanoi to Ho Chi Minh City; Hanoi to Hue overnight is about 12 hours.
One eSIM for the route. Fizen's Vietnam coverage is the Asia plan on Viettel Mobile 4G; for 14 days the 15-day sizes (5, 10 and 20 GB) are the ones that fit.
Data matters most at landing, on the ride app and where signal thins, such as a Ha Long Bay cruise.
Pay cash at the margins, QR in towns. QR payments are spreading from hotels to markets, but family stalls, boats and tips still run on small notes.

Day 1: you land in Hanoi, find the pickup pillar and want a ride before anyone finds you. Day 14: you are in Saigon, paying a market stall with a QR on your phone and wondering where two weeks went. Between them is the route most visitors follow.

This is a planning guide, not a list of sights: for each stop, what you need online and how you pay. For costs, see our two-week Vietnam budget; for the first hour, the airport arrival guide.

What does a 14-day Vietnam itinerary look like?

Days	Stop	Data matters for	How you pay
1-3	Hanoi: Old Quarter, street food, what is new	Landing, ride app, maps in the alleys	Small notes for street food and drinks; QR where shops show a code
4-5	Ha Long Bay: one night on a boat, signal guide	Download offline maps first; signal is patchy at sea	Check the cruise guide for what to pay on board
6-9	Da Nang and Hoi An: Da Nang data, Hoi An food	Rides between the two, maps in the old town	QR in shops and restaurants; tailor deposits are a big payment, check the amount
10-11	Nha Trang: Nha Trang data	Boat day trips, ride app	Ask how a boat day trip takes payment when you book
12-14	Saigon: Saigon data, market QR, Mekong day trip	Rides, maps, the airport on departure	QR at markets and cafes; see the Mekong guide for day-trip payment

Optional swaps: trade Ha Long for Sapa trekking (signal, ATMs and cash) or the Ha Giang loop (signal, cash and QR), or add Phong Nha caves (eSIM, cash and Grab). Riding the whole length instead? See Vietnam by motorbike.

Should you go north to south or south to north?

Either works, and the choice usually comes down to flights. Published planners suggest roughly 4 to 5 days in the north, about 5 on the Central Coast and 3 to 4 in Saigon, mixing overnight trains and one or two domestic flights decided leg by leg, and flying into one city and out of another so you never backtrack (from search snippets of a Layla itinerary, which we could not open in full). South to north is the same route reversed: land in Saigon, finish in Hanoi. For a 10-day trip, drop Nha Trang and trim a day from Hanoi and Saigon.

How do you cover the whole route with one eSIM?

Install it at home on Wi-Fi before you fly, keep your home SIM in for bank codes, and switch the travel line on after landing. As of 2 November 2026, Fizen's Vietnam coverage is the Asia plan for 18 countries, which runs on Viettel Mobile 4G in Vietnam; fixed-data plans slow to 128 kbps after the allowance, and most Fizen eSIMs cannot be topped up, so size it for the full trip. For 14 days the 15-day plans in 5, 10 and 20 GB fit; for 10 days the same 15-day sizes, since a 7-day plan would run out. Internet in Vietnam helps you size it. Check the eSIM tab or fizen.io/esim for current plans.

Your travel eSIM gift is waiting: US$10 of eSIM credit. It is exclusive to new Fizen app users, lands in the eSIM tab the moment you join, and saves you up to 30% on each data plan until it is used. Pay with USDT on Solana or BNB Chain, or by card via Stripe.

Where will you actually need data?

On landing. Pickup points are marked in the Grab app, and the app shows the price up front. Details in the arrival guide.
Between towns. Booking rides and checking the next hotel's address.
On the quiet stretches. Ha Long Bay, Sapa and Ha Giang are where any network struggles, so download maps and tickets first.

How do you pay at each stop?

Vietnam News reported on 28 September 2026 that QR payments are spreading from hotels and shopping centres to markets, restaurants and souvenir stalls, and that one stall owner at Ben Thanh Market said about 70% of customers pay cashless. The margins still run on cash: boats, small family places and tips. Our guide to paying as a tourist covers cards and ATMs. For QR codes: Fizen QR Pay lets foreign visitors in Vietnam pay VietQR bank codes, VNPay, MoMo and ZaloPay codes from USDT. The order: create or import your Fizen wallet (self-custody), get USDT on Solana or BNB Chain into it, deposit from the wallet into QR Pay (KYC per wallet and per device; BNB Chain deposits need no gas, Solana needs a little SOL), then scan and pay. USDT on another network, or another token, cannot be deposited. In Vietnam it pays only Vietnamese account holders' codes, and people who live in Vietnam cannot use it there. Limits: US$800 per payment, US$1,000 per week, no daily limit. USDT moved into QR Pay is governed by the QR Pay Terms, so move in only what you plan to spend. Steps: QR Pay getting started.

What do other route planners say?

From search snippets of published itineraries (we could not open every page): mix overnight trains with a couple of flights, decide leg by leg, and book an open-jaw ticket.
Tour-operator pages put the Hanoi to Hue overnight train at about 12 hours; check current times before you plan around it.

Frequently asked questions

What is the best 14-day itinerary for Vietnam?

A popular and practical one runs north to south: Hanoi, Ha Long Bay, Da Nang and Hoi An, Nha Trang, Saigon, flying the long legs. Swap Ha Long for Sapa or the Ha Giang loop if you prefer mountains.

Should I travel Vietnam from south to north?

You can, and the route is the same reversed. Choose by which city your international flights reach more conveniently, and fly into one city and out of another.

How many days do I need for Vietnam?

Ten days covers Hanoi, Ha Long, Central Vietnam and Saigon at a brisk pace; fourteen adds Nha Trang or another stop and removes the rush.

Do I need more than one eSIM for a Vietnam trip?

No. One Vietnam eSIM sized for the whole trip covers every stop. Fizen's Vietnam coverage is the Asia plan on Viettel Mobile 4G, and most eSIMs cannot be topped up.

Can I pay by QR code all the way through Vietnam?

In towns, markets and restaurants, increasingly yes, but boats, small family places and tips still use cash. Keep small notes and a card as backup.

Your travel eSIM gift is waiting: US$10 of eSIM credit

Exclusive to new Fizen app users: US$10 of eSIM credit lands in the eSIM tab the moment you join and saves you up to 30% on each data plan until it is used. Pay with USDT on Solana or BNB Chain, or by card via Stripe. Visitors in Vietnam can pay local bank QR codes in the same app with QR Pay.
