Important things to know about this route
Cat Ba is an island on the far east of northern Vietnam. Sapa is a mountain town on the far west. It’s good to understand this when planning the journey — you’re traveling from one side of the region to the other.
Despite the distance, there are surprisingly direct transfers available — including the ferry crossing. The trip takes at least 11 hours, but often longer depending on the bus company, breaks, and traffic.
This is not a journey for everyone. If you prefer more comfort, it’s worth considering breaking the trip in Hanoi instead of doing it all in one go.
No matter which option you choose, all routes include a 30-minute ferry ride off Cat Ba Island. And whether you go direct or via Hanoi, the route always passes through Hanoi anyway. There’s no shortcut across northern Vietnam that skips the capital — it’s just how the road network works.
Option 1: Via Hanoi (Recommended for comfort)
How this option works
Step 1 – From Cat Ba to Hanoi:
Take a bus (ferry included) or a private car. Travel time is usually 3.5 to 4 hours. This part is straightforward — the ferry is included in the bus ticket, so you don’t need to arrange that separately.
Step 2 – Break in Hanoi:
Once in Hanoi, you can stretch your legs, enjoy a proper meal, or even stay overnight. This makes a huge difference in comfort compared to being stuck on a bus for 12+ hours straight.
Step 3 – Hanoi to Sapa:
The biggest advantage of traveling via Hanoi is that you have more transport options:
- Sleeper bus: Similar to the direct bus from Cat Ba, but with a break in between.
- Sleeper train: Much more comfortable for many travelers, with beds and the ability to move around — something not possible on a bus. (This option isn’t available directly from Cat Ba.)
- Limousine vans or private cars: You can choose to stay overnight in Hanoi and continue to Sapa the next morning. Also not possible on the direct route. A good option if you prefer daytime travel with more comfort and space.

Option 2: Direct bus from Cat Ba to Sapa
How this option works
Yes, there are direct buses from Cat Ba to Sapa, including the ferry crossing. This is the most popular choice for backpackers and budget travelers looking for the simplest and cheapest option.
Important note: Some buses first drive to Hanoi Old Quarter, take a short break, and then continue to Sapa. Even though it’s called a “direct” bus, it may still mean “via Hanoi — just without changing buses.”
Travel time
- Travel time varies between 10 to 12.5 hours, depending on the bus company, route, and the length of breaks.
Departure options
- Day buses:
- Good for those uncomfortable with night travel.
- Feels longer and more tiring since you’re awake the whole journey.
- Night buses:
- Depart late afternoon or evening, arriving in Sapa early morning.
- Use the ride to sleep and save daytime for activities — though not everyone finds it easy to sleep on buses.
Bus types
- Standard sleeper bus: Reclining bunk-style seats, basic but functional.
- VIP limousine sleeper: Fewer seats, almost double the space, USB chargers, and more comfort.
- Note: These sleeper buses are used for both day and night travel, not only overnight.
Cost
- Prices range from $27 to $38 USD, depending on the bus company and the comfort level.
Booking
- Book online via 12Go Asia.
- Book directly with the bus company or easily through your hotel in Cat Ba, which can help with pick-up and communication.
Pros
- Direct route with no transfers needed.
- Cheapest option.
Cons
- A very long time in one vehicle.
- Less flexible — no option for a train or limousine van like when going via Hanoi.
- If the bus stops for a break in Hanoi, you stay on the bus — you don’t get time to enjoy the city.
Tips for traveling from Cat Ba to Sapa
Bring snacks and drinks
It’s a long journey, and food stops are limited to basic highway-style restaurants. Bring enough snacks, water, and drinks to stay comfortable.
Entertainment is essential
Make sure your phone is fully charged and download podcasts, music, or movies. Bring headphones, as buses can sometimes be noisy with other passengers.
Consider breaking the trip in Hanoi
If you have the time, this makes the journey much more comfortable. You also unlock more transport options like the sleeper train, limousine van, or private car.
Motion Sickness Warning
The final part of the route between Hanoi and Sapa includes mountain passes with plenty of curves. If you’re prone to motion sickness, bring medication.
Book in advance
Buses on this route can sell out, especially the night departures. It’s smart to book at least 1–2 days in advance to secure your spot.
