3-day Vietnam self-drive itinerary

Walk Hanoi, hire a car for Ninh Binh, and decide on Halong — a realistic three-day car-hire plan from Hanoi.

Honest version first: a hire car is only useful for one of these three days. Hanoi’s Old Quarter is a walking city — narrow one-way lanes, constant scooter streams, and nowhere sane to park — so day one stays entirely on foot. Halong Bay cannot be reached without a boat regardless of how you get to the coast, which limits what self-driving actually buys you there. The one leg where a hire car genuinely earns its keep is Ninh Binh, where quiet countryside roads and your own schedule beat a fixed-departure coach. If that ratio does not appeal, the companion 3-day Vietnam itinerary with guided tours covers the same three days entirely by booked package instead.

Why this is a partial self-drive, not a full one

Vietnam is not a mature self-drive market the way Australia or New Zealand is. To legally drive a car here you need your home licence plus an International Driving Permit issued under the 1968 Vienna Convention on Road Traffic — and not every country’s IDP qualifies, so confirm your home country is a Vienna Convention signatory before you book a self-drive car rather than assuming any IDP will do. Many rental operators default to a car-with-driver arrangement for exactly this reason, and for Hanoi traffic specifically that is often the smarter call anyway. Treat “self-drive” on this itinerary as one focused countryside leg, with a driver-included car as your fallback if paperwork or confidence is not there.

• Do not drive yourself in the Old Quarter — walk it, full stop
• Confirm your IDP is Vienna Convention-recognised before booking a self-drive car
• If in doubt, book a car with a driver for the Ninh Binh leg instead of self-driving
• Use Grab for anything in Hanoi beyond walking distance

The 3-day shape at a glance

• Day 1 — Hanoi Old Quarter entirely on foot, no car
• Day 2 — Collect a hire car (or car-with-driver), drive to Ninh Binh for Tam Coc / Trang An
• Day 3 — Halong area by road plus a boat, or return the car and book a cruise instead

Day 1 — Hanoi on foot

Skip the rental desk entirely today. Walk Hoan Kiem Lake before the heat and scooters build, take the Old Quarter’s 36 streets at a wander rather than a checklist, and use a museum or the Temple of Literature as your one indoor block. Dinner is a street-food crawl on foot — this is the one meal in Vietnam where not having a car is a genuine advantage, since half the best stalls sit down alleys no vehicle could reach anyway. Book your hire car for pickup tomorrow morning rather than today; there is no upside to collecting it before you need it.

• Hoan Kiem Lake and Ngoc Son Temple loop, on foot
• Old Quarter street-food wander for dinner
• Confirm hire-car pickup location and required documents (passport, IDP, home licence) for tomorrow

Day 2 — Hire car to Ninh Binh

Collect the car in the morning, away from the Old Quarter’s worst congestion, and head south — about two hours to Ninh Binh province on a decent highway once you clear Hanoi’s outskirts. This is the day self-driving actually pays off: Tam Coc’s rowboat routes between karst peaks and rice paddies, Trang An’s cave-tunnel boat ride, and the Mua Cave viewpoint climb all sit within a compact area, and having your own car means you set the pace between them instead of following a coach timetable. If you decided against self-driving, this is exactly the leg to swap for a car-with-driver or a small-group van tour — the destinations do not change, only who is behind the wheel.

• Tam Coc — rowboat through karst and paddy fields
• Trang An — longer boat ride through cave tunnels
• Mua Cave viewpoint — a steep climb for the classic aerial shot
• Return to Hanoi in the evening rather than pushing on tired roads after dark

Day 3 — Halong by road, or return the car

This is the honest fork in the plan. Driving yourself to Halong City is possible — a sealed highway, roughly three to four hours from Hanoi — but you will still need to book a licensed boat once you arrive, park the car for the day, and drive back that evening or overnight locally before returning it. For most travellers on a tight three-day trip, it is simpler to return the hire car in the morning and book a Halong Bay day cruise with hotel pickup instead, letting someone else handle the ferry-terminal logistics on your last full day. If you are continuing on to a longer trip and already have the car booked for more days, driving to Halong yourself and joining a boat there is a reasonable way to keep using it.

• Option A — drive to Halong City yourself, park, and join a day-boat cruise, then drive back
• Option B — return the hire car and book a Halong Bay day cruise with hotel pickup
• Either way, do not attempt to drive a boat route yourself — cruises require a licensed operator
• Build in airport buffer time regardless of which option you pick

Licence and rental practicalities

• Get your IDP before you leave home — it cannot be issued once you are in Vietnam
• Bring your original home licence alongside the IDP; the permit alone is not accepted
• Expect a security deposit hold on a card for self-drive rentals
• Automatic cars are less common than in Australia — confirm availability when booking

When to just book the guided version instead

If your IDP situation is unclear, if you are not confident reading Vietnamese road signage, or if three days feels too short to bother collecting and returning a car twice, the 3-day Vietnam itinerary with guided tours covers the identical route with packaged transport for all three days. Many travellers land on a hybrid: guided Halong and Ninh Binh day trips, with a hire car saved for a longer central Vietnam leg later in the trip — see our 5-day self-drive itinerary for how that regional split works over more days.
