Short answer: Cat Ba Island is the largest island in the Ha Long Bay area and the best base for Lan Ha Bay. It is about 3–3.5 hours from Hanoi by bus and cable car for 325,000–450,000 VND. Stay two nights: one day on a Lan Ha boat, one in the national park or on the beach.
Cat Ba Island is where you go when you want the karst bays without spending your whole stay on a cruise boat. The town is lively, the national park covers much of the island, and Lan Ha Bay — quieter than Ha Long — starts at the harbour. This guide covers getting there, what to do, what it costs in 2026 and how long to stay.
What Is Cat Ba Island Like?
Cat Ba Island is a large, hilly island at the southern edge of Ha Long Bay, with a busy harbour town on one side and forest-covered national park across much of the rest. It sits inside the Ha Long Bay – Cat Ba Archipelago World Heritage site, extended to include Cat Ba in 2023.
Cat Ba town is not a quiet fishing village any more. The seafront is lined with hotels, seafood restaurants and bars, and weekends in summer are busy with domestic visitors. The reason to come is what surrounds the town: Lan Ha Bay’s floating villages and lagoons, jungle trails, and small beaches tucked between cliffs.
How Do You Get to Cat Ba Island From Hanoi?
The easiest way to get to Cat Ba Island from Hanoi is a combo ticket: bus to the coast, then cable car or boat across. It takes about 3–3.5 hours in total and costs 325,000–450,000 VND (~$12.50–17.30 USD) with hotel pickup.
| Crossing | Time | Notes |
|---|---|---|
| Cable car (Cat Hai – Phu Long) | 10–15 minutes over about 3.9 km | About 70,000 VND one way; runs roughly 08:30–15:45 |
| Speedboat | 5–7 minutes | Usually part of the combo |
| Car ferry | 25–35 minutes | Used by vehicles and later buses |
Mind the cable car hours. It stops around 15:45, so afternoon buses switch to the boat or ferry, and the last crossings of the day fill up in summer. Standard buses start from about $10.50 USD, VIP limousine vans about $15–17 USD.

What Is There to Do on Cat Ba Island?
The best thing to do on Cat Ba Island is a day on Lan Ha Bay by boat and kayak. After that, pick between the national park, the beaches and the island’s wartime history, depending on how active you feel.
- Lan Ha Bay boat day: boats leave from Ben Beo harbour near town, visiting floating fishing villages, lagoons and small beaches, usually with kayaking. The Lan Ha fee is roughly 120,000 VND, paid at the harbour.
- Cat Ba National Park: forest trails and a summit viewpoint, open 07:00–17:00, 60,000–80,000 VND. It is home to the Cat Ba langur, one of the rarest primates in the world — sightings are rare, but the park exists largely to protect it.
- Hospital Cave: a wartime hospital built inside a limestone hill, 40,000 VND. Short, interesting, and a good rainy-hour option.
- Cat Co beaches: three small beaches, Cat Co 1, 2 and 3, a short walk or ride from town. Fine for a swim; not the reason to come.
- Cannon Fort: a hilltop viewpoint over town and the bay. Several 2026 sources report it closed to visitors, so check locally before walking up.
How Much Does Cat Ba Island Cost in 2026?
Cat Ba Island costs little beyond transport and your boat day. Prices below were checked in September 2026 and converted at roughly 26,000 VND to $1 USD.
| Item | Price |
|---|---|
| Hanoi – Cat Ba combo (bus + crossing), one way | 325,000–450,000 VND (~$12.50–17.30 USD) |
| Cable car only, one way | About 70,000 VND (~$2.70 USD) |
| Lan Ha Bay fee | Roughly 120,000 VND (~$4.60 USD) |
| Cat Ba National Park | 60,000–80,000 VND (~$2.30–3.10 USD) |
| Hospital Cave | 40,000 VND (~$1.50 USD) |
Lan Ha boat days are sold by nearly every hotel and agency in town, at a wide range of prices and group sizes. Ask how many people are on the boat, whether kayaks and the bay fee are included, and how much of the day is on the water — those three answers explain most of the price differences.
Is Cat Ba Island Better Than a Ha Long Bay Cruise?
Cat Ba Island is better if you want flexibility, land-based activities and lower costs; an overnight cruise is better if you want to sleep on the water and see the bay with no effort. They suit different travellers rather than one beating the other.
| Cat Ba Island base | Overnight cruise | |
|---|---|---|
| Sleep | Hotel or homestay in town | Cabin on the boat |
| Bay time | A full day on a Lan Ha boat | Afternoon, sunset and morning |
| Other activities | National park, beaches, caves, cafés | Mostly on board |
| Cost | Lower, pay as you go | Roughly $145–200 USD mid-range, all-in |
| Best for | Independent and active travellers | Short trips, couples, families wanting ease |
When Is the Best Time to Visit Cat Ba Island?
The best time to visit Cat Ba Island is late September to November, when the sea is calmer, the air is clearer and the summer crowds have gone. April to June is also good, warm enough to swim with fewer storms.
July and August are peak domestic season: hot, busy, and inside the typhoon season that runs from late May to early November. Boats do not sail when the port authority closes the water, so keep a spare day. December to February is cool and often grey — fine for walking, poor for swimming. Our Vietnam weather guide has the month-by-month view.
How Many Nights Do You Need on Cat Ba Island?
Two nights is right for Cat Ba Island: one full day on Lan Ha Bay and one for the national park, a beach or simply slowing down. One night leaves you only a half day, because the journey eats both ends.
Three nights suits travellers who want to add climbing, a second boat route or a proper rest between busier stops. Planning the bigger picture? Our guide to how many days you need in Vietnam shows how the island fits alongside Hanoi and the south.

FAQ: Cat Ba Island
How do I get to Cat Ba Island from Hanoi?
By combo ticket: a bus to the coast, then a cable car, speedboat or ferry to the island. It takes about 3–3.5 hours and costs 325,000–450,000 VND with hotel pickup.
Is Cat Ba Island worth visiting?
Yes, as a base for Lan Ha Bay and for travellers who want hiking, caves and beaches as well as bay views. It is less worth it if you only want to sleep on a boat.
How many days do you need on Cat Ba Island?
Two nights: one day on a Lan Ha Bay boat and one for the national park or a beach. One night leaves only a half day on the island.
Is Cat Ba Island better than Ha Long Bay?
It is different. Cat Ba is a land base with access to quieter Lan Ha Bay; Ha Long is usually seen on a cruise. Many travellers prefer Lan Ha for fewer boats.
Can you swim on Cat Ba Island?
Yes, at the Cat Co beaches near town and on small beaches during Lan Ha boat trips. Swimming is best from April to October outside storm days.
What is the Cat Ba cable car schedule?
The Cat Hai – Phu Long cable car runs roughly 08:30–15:45 and costs about 70,000 VND one way. After that, crossings switch to boats and the car ferry.
