We want to depart at night, is the service available?

We provide service at any time you need, however, trips departing between 10 PM the previous day and 5 AM the following day will incur a surcharge of 10-15% on the total price.

Can I stop along the way (for lunch, sightseeing, etc.)?

This depends on the time and purpose of your stop. Generally, the driver will assist with short stops (around 10 minutes) for restroom breaks or snacks, but not too frequently. If the itinerary changes because you wish to visit a different location outside the route, we may charge an additional fee. Please contact our customer service if you intend to change the itinerary for further advice.

Is there a luggage limit on this private car service?

Our private car transfer accommodates standard luggage without extra charge. If your group is travelling with oversized bags, sports gear, or additional equipment, simply let us know at booking and we will assign a vehicle with sufficient space at no extra cost.

Can I change the pick-up or drop-off location after booking?

Yes. You may update the pick-up or drop-off address up to 1 hour before the scheduled departure. Changes after that point may not be possible, as your driver will already be on the way to collect you.

Does the driver speak English?

Our private car service driver can handle basic conversational English for everyday needs during the journey. If you require more detailed assistance at any point, simply message us via WhatsApp and our operator will contact your driver immediately on your behalf.

Does the vehicle provide child seats?

Yes, we offer child seats for children under 5 years old with our private car service, at an additional cost of $13 per seat per trip. Please inform us at the time of booking so everything is ready before your departure.

Can I bring my pet with me?

Yes. We allow pets to travel with you when using our private car service. Your pet must be equipped with a sturdy, bottom-filled cage or wear a muzzle and leash (for pets over 7kg). Please supervise your pet throughout the trip to avoid safety risks. After the trip, please follow the driver's instructions to help clean the vehicle. We may charge a fee if the unsanitary conditions cannot be immediately rectified (e.g., your pet urinates or defecates on the floor/seats of the car).

Cao Bang City to Halong Bay private car

Overview

The Cao Bang City to Halong Bay private car transfer is the most comfortable and scenic way to connect the historic northern frontier city of Cao Bang with the UNESCO-listed karst seascape of Halong Bay in Quang Ninh province. This 7-hour, 300 km route takes you directly southeast from the lush mountains and rivers of Cao Bang, passing through the stunning landscapes of Lang Son province, crossing modern expressways, and arriving at the dramatic limestone islands and emerald waters of one of Vietnam's most iconic destinations.

To reach Halong Bay as quickly as possible, we choose the route: Cao Bang City → National Highway 4A → Lang Son → National Highway 1A → Hanoi – Hai Phong Expressway → National Highway 18 → Halong Bay. This route uses modern, well-paved expressways and has a shorter travel time compared to slower mountain detours. If you prefer a different route or wish to add stops (e.g., at the famous Ban Gioc Waterfall – one of Vietnam's most spectacular waterfalls, the historic Pac Bo Cave where Ho Chi Minh lived after his return from abroad, the scenic Ma Phuc Pass with its breathtaking mountain views, or the beautiful Bai Chay Bridge with its stunning views of the bay), please contact A21 Tours for more details.

We offer a wide range of vehicle sizes tailored to fit couples, families, or larger travel groups perfectly—from 4-seater sedans to 7-seater SUVs and 16-seater minivans. Our experienced drivers know the safest and most efficient routes through the mountain passes and expressways, and they can easily communicate using basic English or translation software. To make your journey truly special, you have the flexibility to choose your own specific stops to rest, take photos, and discover hidden gems at your own pace.

Best of all, your upfront fare covers all tolls, fuel, and the driver's fee, so you never have to worry about unexpected extras along the way. Enjoy a peaceful ride with comfortable seating, powerful air conditioning, and complimentary cold drinks throughout the trip.
