Where Is Cat Ba Island?
Cat Ba Island is in the Cat Hai Special Zone of Hai Phong City (formerly Cat Hai district), about 150 km east of Hanoi and around 50 km from central Hai Phong. Cat Ba is the largest of the 367 islands that make up the Cat Ba archipelago, which lies just south of Ha Long Bay.
Cat Ba covers roughly 260 km², and its highest point is Cao Vong mountain (322 m). Much of the land is protected limestone forest, while the eastern coast opens onto Lan Ha Bay, a calmer, less crowded part of the same karst seascape as Ha Long Bay.
- Vietnamese name: Đảo Cát Bà (Cat Ba Island). The wider group of islands is called Quần đảo Cát Bà (Cat Ba archipelago).
- Main town: Cat Ba Town, on the south coast, with most hotels, restaurants and boat piers.
- UNESCO status: The Cat Ba archipelago has been a UNESCO Biosphere Reserve since 2004. On 16 September 2023, UNESCO added the archipelago to the Ha Long Bay World Natural Heritage site, now called “Ha Long Bay – Cat Ba Archipelago”.
Is Cat Ba Island Worth Visiting?
Yes, Cat Ba Island is worth visiting if you want Ha Long Bay–style scenery with beaches, trekking and fewer crowds. Unlike a day cruise in Ha Long, Cat Ba lets you stay on the island, swim, hike in a national park and explore Lan Ha Bay by kayak.
- Scenery: Limestone mountains, emerald water, caves and karst valleys.
- Nature: Cat Ba National Park protects tropical forest, mangroves and the rare Cat Ba langur.
- Activities: Kayaking, boat trips, beach time, trekking, cave visits and fishing village tours.
- Value: Hotels and food in Cat Ba Town are generally cheaper than on Ha Long cruises.
Cat Ba suits couples, families and friend groups who want two or three relaxed days in nature after the busy streets of Hanoi.
When Is the Best Time to Visit Cat Ba Island?
The best time to visit Cat Ba Island is from April to June and from September to October, when the weather is warm, the sea is calm and the island is less crowded.
- April – June: Sunny days, warm water and good visibility for kayaking and boat trips.
- July – August: Peak domestic holiday season. It is hot and lively, but storms and heavy rain can cancel boat tours, so keep a flexible day.
- September – October: Pleasant weather and thinner crowds, though early September can still bring storms.
- November – March: Cool and quiet. It is too cold for most people to swim, but good for trekking, cruises and slow travel. Planning a Diwali break? Diwali falls on 8 November 2026 and 29 October 2027, both in Cat Ba’s cooler, quieter season.
Whatever the month, check the weather forecast a day before any boat trip, because sea conditions decide whether tours run.
How Do You Get to Cat Ba Island from Hanoi?
The easiest way to reach the island is to fly into Hanoi, then take a combined bus and boat (or cable car) transfer that takes about 3 to 4 hours.
From India to Hanoi
Vietnam has direct flights from six Indian cities: Delhi, Mumbai, Kolkata, Bengaluru, Hyderabad and Ahmedabad. From Chennai you will need one stop. For Cat Ba, most Indian travellers fly into Hanoi (Noi Bai International Airport). Indian passport holders can apply online for a Vietnam e-visa (US$25, about ₹2,375) and should also complete the Digital Arrival Card before landing.
From Hanoi to Cat Ba
From Hanoi, the road runs along the Hanoi – Hai Phong expressway to the coast. You then cross to the island in one of three ways:
- Bus + express boat or cable car combo: Several operators sell through tickets from Hanoi to Cat Ba Town. They take about 3–3.5 hours and cost from about 300,000 VND (≈ ₹1,099) one way, or about 380,000 VND (≈ ₹1,392) by limousine van.
- Cat Hai – Phu Long cable car: This 3,955 m sea-crossing cable car takes 10–15 minutes and costs 70,000 VND (≈ ₹256) per person each way. Children under 1 m ride free. Cabins run from 8:30 am, with the last departure at about 3:30 pm.
- Dong Bai – Cai Vieng ferry: This car ferry takes about 25 minutes and costs around 14,000 VND (≈ ₹51) per foot passenger. It is the usual choice for private cars.
From Hai Phong to Cat Ba
From Hai Phong city, the express boat package from Ben Binh pier (with a short bus link to Dong Bai) reaches Cat Ba in about 1.5–2 hours. Fares are about 220,000–250,000 VND (≈ ₹806–916) per adult one way. There are usually two departures a day, in the morning and the early afternoon.
From Ha Long Bay to Cat Ba
Many Ha Long cruises sail into Lan Ha Bay and moor near Cat Ba. You can also take a boat transfer from the Ha Long side to Cat Ba, which takes around 1–2 hours depending on the route, so combining both bays in one trip is easy.
Here is a quick summary of transfer options and typical fares (checked in November 2026):
| Route / Option | Travel time | Typical fare (one way) |
| Hanoi – Cat Ba Town (bus + boat/cable car combo) | 3 – 3.5 hours | From 300,000 VND (≈ ₹1,099) |
| Cat Hai – Phu Long cable car | 10 – 15 minutes | 70,000 VND (≈ ₹256) |
| Dong Bai – Cai Vieng ferry (foot passenger) | About 25 minutes | 14,000 VND (≈ ₹51) |
| Hai Phong (Ben Binh) – Cat Ba express boat | 1.5 – 2 hours | 220,000 – 250,000 VND (≈ ₹806 – 916) |
Fares and timetables change by season, so confirm them a few days before you travel or let your tour operator arrange the transfer.
What Are the Best Things to Do on Cat Ba Island?
The best things to do on Cat Ba Island are exploring Lan Ha Bay by boat or kayak, trekking in Cat Ba National Park, enjoying the views from Cannon Fort and relaxing on the Cat Co beaches. Here are the best experiences, in the order most travellers enjoy them.
1. Explore Lan Ha Bay by Boat and Kayak
Lan Ha Bay is the highlight of any Cat Ba trip. Half-day and full-day boat tours leave from Cat Ba Town and stop at quiet lagoons, small beaches and limestone caves. Popular stops include Ba Trai Dao (Three Peaches) beach and the Dark and Bright Cave, which you paddle through by kayak.
Kayaking here is calm and beginner-friendly. Life jackets are provided, and guides usually lead groups through the safest channels.
2. Trek in Cat Ba National Park
Cat Ba National Park covers more than 15,000 hectares of forest, mangroves and sea, and is the core of the Cat Ba Biosphere Reserve. The most popular trail climbs to Ngu Lam peak for a 360-degree view over the forest canopy. The Ngu Lam trek takes about 2–3 hours return, and some sections are steep and rocky. For an easier walk, choose the Kim Giao forest trail, a short loop under ancient trees.
- Entrance fee: about 80,000 VND (≈ ₹293) per adult. Fees can change, so check at the gate.
- Opening hours: roughly 7:00 am – 5:00 pm.
- Tip: Start early, wear proper shoes and carry water and mosquito repellent.
3. See Cat Ba Wildlife and the Cat Ba Langur
Cat Ba is one of Vietnam’s richest wildlife areas. Cat Ba is the only home of the Cat Ba langur (golden-headed langur), one of the rarest primates in the world, with fewer than 70 left in the wild, according to conservation estimates. Sightings are rare. Your best chance is an early-morning guided trek or a boat trip along the remote cliffs, where conservation teams monitor the langurs. You may also spot birds, butterflies and macaques.
4. Enjoy the View from Cannon Fort
Cannon Fort sits on a hilltop just above Cat Ba Town. It has wartime gun emplacements, tunnels and the best panoramic view of the town, Cat Co beaches and Lan Ha Bay. Go in the late afternoon for sunset. You can walk up, or take a motorbike taxi to the entrance.
5. Relax on the Beaches
Cat Ba’s beaches are small, sheltered and backed by green cliffs. The beaches worth knowing are:
- Cat Co 1, 2 and 3: The best-known beaches, a short walk from Cat Ba Town. A scenic cliffside walkway links Cat Co 1 and Cat Co 2.
- Tung Thu Beach: A quieter beach with a peaceful atmosphere and clear water.
- Ba Trai Dao (Three Peaches) Beach: A small beach in Lan Ha Bay, framed by three rounded islets and reached by boat.
- Tiger Beach and Moody Beach: Remote beaches in Lan Ha Bay, popular for deep-water soloing and sea-cliff climbing.
6. Visit Hospital Cave
Hospital Cave is a three-storey cave that was turned into a secret hospital during the Vietnam War. Short guided visits take you through the old operating rooms, wards and escape tunnels. Hospital Cave is an easy stop between Cat Ba Town and the national park.
7. Walk Through Trung Trang Cave
Trung Trang Cave is a limestone cave about 300 m long inside Cat Ba National Park, near the main entrance. A short path leads past stalactites and stalagmites in unusual shapes, and the visit takes about 20–30 minutes. Entry is normally included in the national park ticket.
8. Experience Local Life at Cai Beo Fishing Village
Cai Beo is one of the oldest fishing villages in Vietnam, just outside Cat Ba Town. Families live and farm fish in colourful floating houses on the water. A short boat ride here is the best way to see Cat Ba local life, and many Lan Ha Bay tours stop here first.
9. Cycle or Hike to Viet Hai Village
Viet Hai is a tiny village hidden in a valley inside the national park. You can reach it by bicycle, on a guided trek or by boat. Rice fields, stilt houses and simple homestays make it a peaceful half-day trip for travellers who want a slower pace.
10. Go Night Squid Fishing
Night squid fishing is a fun evening activity in Lan Ha Bay. Boats use bright lights to attract squid, and guests try their luck with simple lines before the catch is cooked on board. Vegetarians can still enjoy the boat ride and the night views.
11. Try Local Cuisine
Seafood is Cat Ba’s speciality. Grilled scallops and oysters, crab, mantis shrimp, squid and fish are sold by weight, and prices vary by type and season, so always ask before ordering. For vegetarian travellers, most restaurants in Cat Ba Town can prepare rice, noodles, vegetable stir-fries and tofu dishes. If you need Jain or strictly vegetarian meals, ask your tour operator to arrange them in advance.
Which Cat Ba Island Cruises Should You Choose?
The best way to see Cat Ba and Lan Ha Bay in comfort is an overnight cruise that combines Ha Long Bay, Lan Ha Bay and the Cat Ba archipelago. Most of these cruises depart from the international marina on Tuan Chau Island in Ha Long.
Five-star cruises offer cabins with private balconies, sundecks, restaurants, spas, and activities such as kayaking, cooking classes and tai chi. Here are some well-known cruises that sail into Lan Ha Bay:

Cat Ba Island or Ha Long Bay: Which Is Better?
Choose Ha Long Bay for a classic, easy cruise, and Cat Ba for beaches, trekking and a quieter stay. Many travellers do both in one trip.
| Factor | Cat Ba & Lan Ha Bay | Ha Long Bay |
| Crowds | Fewer boats, quieter lagoons | Busier, especially on day trips |
| Activities | Kayaking, trekking, beaches, caves, villages | Cruising, caves, Ti Top island, kayaking |
| Stay | Hotels in Cat Ba Town or overnight cruises | Mostly overnight cruises or Ha Long city hotels |
| Best for | Nature lovers and active travellers | First-time visitors and families who prefer comfort |
If you are torn, spend one night on a Ha Long cruise and one night on Cat Ba. For ideas on the Ha Long side, see our list of things to do in Halong Bay. Want to add another northern island to your trip? Remote Co To Island has some of the cleanest beaches in the Gulf of Tonkin.
Cat Ba is one of many beautiful islands in Vietnam. If you prefer warm water all year round, Phu Quoc in the south is the top choice, and our Phu Quoc tour packages from India make it easy to plan.
How Many Days Do You Need on Cat Ba Island?
Two days and one night is enough to see the highlights of Cat Ba, but three days gives you time to relax, trek and explore Lan Ha Bay without rushing.
- Day 1: Transfer from Hanoi, check in, Cai Beo fishing village, sunset at Cannon Fort.
- Day 2: Full-day Lan Ha Bay boat trip with kayaking, swimming and lunch on board.
- Day 3 (optional): Morning trek in Cat Ba National Park and Trung Trang Cave, then return to Hanoi.
Cat Ba also works well for honeymooners. Cat Ba’s quiet beaches, sunset views and private boat trips fit perfectly into Vietnam couple tour packages. If your family wants more time by the sea, you can pair Cat Ba with central or southern beaches in our Vietnam beach holiday packages.
Vietnamtour.in planner tip: For Indian families with elderly parents, we suggest the cable car instead of the ferry and a private Lan Ha Bay boat, so the vegetarian lunch, the pace and the swimming stops can all be adjusted to your group.
