Monkey Island Cat Ba: What to Know Before You Go
A practical guide to Monkey Island in Lan Ha Bay: how to get there, what the monkeys are like, the viewpoint hike, and which Beka tours stop there.
Traveling from Sapa to Cat Ba Island takes around 10 to 12 hours by the most convenient overnight bus, covering roughly 450 to 500 km depending on the route. The easiest choice is a sleeper or cabin bus that continues toward Hai Phong and includes the island crossing. Travelers can also combine train, bus and ferry, or choose a private car for greater flexibility.
This Sapa to Cat Ba guide covers the distance and travel time, the three ways of making the journey, bus schedules and prices, the return trip and what to check before booking.
The Sapa to Cat Ba Island distance is approximately 450 to 500 km by road, depending on the route and where the journey starts and ends. Because Sapa is in the northern mountains while Cat Ba lies off the coast of Hai Phong, the journey combines long-distance road travel with a ferry or other sea crossing. The same trip is also written as Sa Pa to Cat Ba.

For most visitors, the Sapa to Cat Ba bus is the simplest solution because you can travel overnight and arrive in Cat Ba in the morning. Several operators now sell a single ticket covering the full journey, although the exact vehicle and ferry arrangement can vary.

The Sapa to Cat Ba Island bus is the most practical option for travelers who want to save daytime hours. Most services leave Sapa in the evening and arrive in Cat Ba early the next morning.
Some services operate as a through bus, meaning passengers remain on the same bus while it travels via the Hanoi and Hai Phong corridor and crosses to Cat Ba. Other services may involve a connection, so always check whether your ticket is truly no-transfer before booking.
A current direct sleeper service departs Sapa at 21:00 and arrives in Cat Ba at approximately 07:00 the following morning. The listed fare starts at 650,000 VND per person, with the ferry crossing included.
Other operators publish departures around 20:00 to 22:00, with journey times of approximately 10 to 12 hours. Prices commonly start from about 650,000 VND, while VIP cabin services can cost more. Because schedules and prices can change by season, weekends and holidays, confirm the departure time and vehicle type when booking.
Most buses pick up passengers from central Sapa, particularly offices or meeting points along Dien Bien Phu Street, while some operators provide hotel pickup within Sapa Town.
On arrival, buses generally drop passengers in Cat Ba Town, making it easy to continue to your hotel, have breakfast or join a Lan Ha Bay tour.

If the sleeper bus is sold out, the train route is a useful alternative, although it takes longer and requires more changes. First, travel from Sapa to Lao Cai Railway Station, then take a train to Hanoi. Current train services include a daytime option departing Lao Cai around 12:05 and an overnight option around 21:30, with journeys of roughly 7.5 to 8 hours.
From Hanoi, continue by bus or private transfer toward Hai Phong and then cross to Cat Ba. That final section is the same one every route uses, and it is covered in full in our Hanoi to Cat Ba guide.
Another alternative is to travel from Sapa to Ha Long, then continue to Cat Ba via Tuan Chau and Gia Luan. The Cat Hai tourism document identifies Tuan Chau as a traditional access route to Cat Ba, with the ferry arriving at Gia Luan before travelers continue by road toward Cat Ba Town.
Tuan Chau Ferry updated its timetable with effect from 6 September 2026 and now runs five sailings each way, so this is a reliable connection rather than a fallback. Current departure times are listed in our Tuan Chau to Gia Luan ferry guide.
A private car is the most flexible option for the Sapa to Cat Ba Island journey. You can leave Sapa at a time that suits your itinerary, stop for meals or breaks and travel directly toward Cat Ba. Current private-transfer prices start at approximately 195 to 200 US dollars for a sedan, with larger SUVs and minivans costing more, and published journey times are around 8 to 10 hours.
For groups of three or more, a private car can become more attractive because the fare is charged per vehicle rather than per passenger. Always confirm whether the ferry ticket and vehicle crossing are included in the quoted price, since a private car still cannot reach Cat Ba without a boat or the cable car.
The final approach follows the transport network through Hai Phong and the island. The Cat Hai tourism document records Route 356 as the main road crossing Cat Ba, connecting the Cai Vieng area with Phu Long, Hien Hao, Xuan Dam, Tran Chau and Cat Ba Town.
Route 356 opened on 31 March 2002 and runs 31 km to the Ang Soi junction in Cat Ba Town, and the section from Cai Vieng was resurfaced in 2020 to a width of 9.5 meters. The alternative to the ferry is the Cat Hai to Phu Long cable car, a line 3,955 meters long carrying up to 4,500 passengers an hour.

Choose the sleeper bus if you want the best balance of price, convenience and travel time. An overnight departure lets you sleep during most of the journey and arrive in Cat Ba early enough to enjoy the island on the same day.
Choose train, bus and ferry if you prefer trains, need an alternative when buses are sold out or want to break the long journey into separate sections. It is slower but gives you more flexibility over each leg.
Choose a private car if you are traveling with family, carrying several bags or simply want a door-to-door journey without sharing the vehicle. It is the most comfortable option, particularly for groups.
The return journey can usually be arranged as a Cat Ba to Sapa overnight sleeper bus, with some operators offering direct services and others using a connection. Current published services show direct sleeper options departing Cat Ba in the afternoon or early evening and reaching Sapa the following morning. Because departure times vary by operator, check the exact schedule before booking your return ticket.
If you are taking a Lan Ha Bay day tour before returning to Sapa, choose a tour that finishes in Cat Ba Town early enough to reach your bus pickup point comfortably. This allows you to enjoy the bay during the day and travel overnight toward Sapa, and departure times are listed on the Lan Ha Bay hub page.
When booking your Sapa to Cat Ba transfer, confirm four details: departure time, pickup location, vehicle type and whether the ferry is included. For the easiest experience, choose a combined ticket that covers the journey from Sapa to Cat Ba Town rather than purchasing every leg separately.
You can contact Beka Travel to check current availability and arrange a suitable bus or private transfer for your travel date. Current transfers and tours are listed at bekatravel.com.
Current overnight services commonly depart between 20:00 and 22:00. One published direct service leaves Sapa at 21:00 and arrives in Cat Ba at around 07:00 the next morning.
