Cat Ba Island: Lan Ha Bay, the park, and how to get there in 2026
The largest island in the Ha Long archipelago and the gateway to Lan Ha Bay — the same karst scenery as Ha Long, minus the cruise crowds. Roughly 100 km² of tropical jungle, one of the world's rarest primates in the national park, climbing straight off the water and three beaches within walking distance. With the new expressway and cable car, it's 3–4 hours from Hanoi.
Cat Ba is the big island southwest of Ha Long Bay, and the main gateway to Lan Ha Bay: the same emerald karsts, but without the cruise liners and selfie-stick crowds. Your base is Cat Ba Town on the south coast — a fishing town that has sprouted hotels and high-rises in recent years, but still the jumping-off point for the national park, the cliffs and the bay. Budget at least two days: one for the bay and the cliffs, one for trekking and caves.

- Monkey Island (Đảo Khỉ): Half-day boat trip, wild macaques, small beach
Getting to Cat Ba
This used to eat half a day of changes and waiting. It is far easier now: the Hanoi–Hai Phong expressway plus the Cát Hải–Cat Ba cable car have stitched the island onto the mainland, and the whole trip from Hanoi comes in at 3–4 hours. The simplest option is a combined bus-plus-ferry (or cable car) ticket, with departures at 07:30, 10:30 and 14:00. Coming from central Vietnam, most people route through Hanoi first.
| Route | Mode | Time | Price |
|---|---|---|---|
| Hanoi → Cat Ba | Bus + ferry / cable car combo | 3–4 h | 200,000–250,000 VND (~$8–10) |
| Cát Hải → Cat Ba | Cable car | 10 min | 200,000 VND (~$8) one way |
| Hai Phong → Cat Ba | Speedboat | 45–60 min | 250,000 VND (~$10) |
| Got → Cat Ba | Ferry Got → Cái Viềng | 10–15 min | 25,000 VND (~$1) |
The cable car runs across the strait on two of the tallest pylons in the world and drops you on the north of the island, about 20 km from Cat Ba Town by shuttle or motorbike. If you would rather not rush, the plain Got–Cái Viềng ferry (25,000 VND) also carries cars and bikes, though it too lands on the north. The speedboat from Hai Phong is the smoothest — it drops you straight in the centre of town.
You can also come from the town of Ha Long, but you change through Hai Phong. Flying in, the nearest hubs are Hanoi and Hai Phong (Cat Bi airport). For full timetables and fares on buses, boats and limousine vans, see our Ha Long transport guide. One tip: pay for the ferry in cash, ideally in small notes.
Rock climbing — the island's main draw
Cat Ba is Vietnam's climbing capital. There are 120 sport routes across 13 crags, graded from 4a to 8a. A first-timer with no experience can top out a beginner wall within half an hour, while a seasoned climber will find overhangs that make them sweat.
Where to climb
Butterfly Valley is the main venue. Walls up to 30 metres, more than 60 routes, 30 minutes by motorbike from Cat Ba Town. Overhangs, slabs, cracks — all wrapped in jungle, with no city noise.
Hidden Valley is the second-most-popular crag. Routes run from gentle slabs to steep verticals, so it suits every level, and it sees fewer people than Butterfly.
Moody Beach hosts half-day sessions for anyone touching a rope for the first time. The cliffs rise straight from the water, with views over the bay.
Deep Water Soloing in Lan Ha Bay
This is a whole different thrill. There are 230 lines on 24 crags, graded 4a–7c+. You climb the limestone above the water with no rope — if you come off, you drop into the warm bay. Lan Hạ Bay is rated the best Deep Water Soloing spot in all of Southeast Asia.
You boat out from Cat Ba Town and reach the walls in about 20 minutes. Then it is cliff to cliff: climb, jump, swim to the next one. It is dangerously easy to get hooked.

Lan Ha Bay — the quiet alternative to Ha Long
Some 400 limestone karsts scattered across emerald water. Essentially the same scene as Ha Long, minus the crowds. Cruise liners don't come here — only kayaks, small boats and fishermen's sampans.
Lan Hạ starts right off Cat Ba's eastern shore. This is where you find floating fishing villages, wild beaches on uninhabited islets and caves only a handful of people reach.
Entry to the archipelago is 120,000 VND (~$5). Kayaking runs from about $15 for half a day. A full-day Lan Ha boat trip with lunch and a couple of coves starts around 500,000 VND (~$19). Or take a proper overnight cruise across Ha Long and Lan Ha for one or two nights, sleeping on board, from around 400,000 VND (~$16) a night.
Lan Ha from Cat Ba, or a Ha Long cruise? Want it quieter, cheaper and closer to the water — start from Cat Ba: small boats, kayaks, empty beaches, no queues at the caves. Want service on board, the famous Ha Long views and a hotel-to-hotel transfer — book a classic cruise. On the water it is essentially the same archipelago; the difference is the crowd and the price. For the boats themselves, see our Ha Long and Lan Ha cruise guide.
This is exactly where the Deep Water Soloing lines are — the cliffs rise straight from the sea, and the depth is safe for jumping.
The national park and caves
Cat Ba National Park (established 1986) is tropical forest, mangroves and karst lakes, with more than 100 species of animals and birds.
Its pride is the voọc Cát Bà (Cat Ba langur), a white-headed monkey and one of the rarest primates on Earth. Only around 70 survive, all of them here on the tops of the limestone cliffs — the species lives nowhere else in the world. Spotting one is hard, but you get a chance on an early-morning trek or a boat run along the eastern shore.
Trekking
Several trails, from easy (2 hours) to serious (6 hours with climbs). The most popular leads to a summit with a view over the whole archipelago. The path is marked but slick after rain, so bring shoes with grip.
Caves
- Trung Trang Cave — 300 metres of underground galleries lined with stalactites. Entry 80,000 VND (~$3).
- Hospital Cave (Hang Quân Y) — a secret military hospital from the American War, three storeys inside the cliff. Entry 80,000 VND (~$3).
Entry to the park itself is 80,000 VND (~$3), plus 5,000 VND for motorbike parking.
Cat Ba's beaches
Three Cát Cò beaches sit within walking distance of the town. Number 1 is the most developed — loungers, showers, cafés. Number 2 is compact and quieter. Number 3 is the wildest, but takes a little longer to reach along a cliff path.
Yellow sand, clean water. Swimming season runs May to September. Outside that you can sunbathe, but the water is cool for a dip (22–24 °C). Be warned: in summer the whole country turns up, and on weekends the Cat Co beaches are packed — the best light and empty sand come before 9am.
Cannon Fort
Above the Cat Co beaches sits Pháo Đài Thần Công — an old fort with coastal guns from the French and wartime eras. It is now the island's best viewpoint: from the hill you look over Cat Ba Town, the mouth of Lan Ha Bay and karsts scattered to the horizon. Entry is 80,000 VND (~$3), and sunset is the time to go.
Monkey Island
Đảo Khỉ is a half-hour boat ride: wild macaques, a small beach and a zipline. The trip starts from about 150,000 VND (~$6). The macaques can be brazen, so keep food and shiny objects out of sight.
Where to stay and eat
Cat Ba is the cheapest bed in the region. How it stacks up against Bai Chay hotels, Tuan Chau resorts and a night on a junk is in where to stay in Ha Long.
Where to stay
| Tier | Examples | Price/night |
|---|---|---|
| Budget | Secret Garden Hostel, Mr Zoom Hostel | ~$5–10 |
| Mid-range | Quang Tung Hotel, Cat Ba Central Hotel 2 | ~$20–50 |
| Premium | Flamingo Cat Ba Resorts, Hotel Perle D'Orient | ~$80–200 |
The whole budget scene is in Cat Ba Town, along the waterfront. Fair warning: the town is densely built up, with high-rises and hotel blocks now lining the shore — the sleepy fishing-village feel is long gone. For quiet and views you head out to the park and the bay, not into town. Flamingo sits on its own headland, with a private beach and karst views.
Where to eat
Seafood here is cheaper than on the mainland. The prawns and squid are fresh, landed that morning. A typical café bill runs 100,000–200,000 VND (~$4–8).
Reliable spots: The Little Leaf Restaurant (vegetarian plus seafood), Secret Garden Restaurant (European menu) and Casa Bonita. Most menus have English, and card payment is patchy — carry cash.
Practical tips
The best window is October to April — dry, comfortable, prime climbing. May to September is hotter and more humid, but Deep Water Soloing runs year-round and the park is at its greenest.
Motorbike rental is 100,000–150,000 VND a day (~$4–6). The roads are decent, though the mountain switchbacks want some riding experience. To rent, you technically need an International Driving Permit with the motorbike category; enforcement is loose, but your travel insurance may not cover you without it.
Pack trekking shoes, swimwear (for DWS), mosquito repellent and a waterproof phone case. Climbing gear is supplied by the operators.

FAQ
How do you get to Cat Ba from Hanoi?
The easy way is a combined bus-plus-ferry (or cable car) ticket, 200,000–250,000 VND (~$8–10), with three departures a day. With the Hanoi–Hai Phong expressway and the Cát Hải–Cat Ba cable car, the trip now takes 3–4 hours. Cheaper: take a bus to Hai Phong yourself and catch the public ferry for 25,000 VND (~$1), but you change and wait.
How much does rock climbing cost on Cat Ba?
A half-day session with a guide and full gear starts around $25. A full day with Deep Water Soloing runs from about $45. Everything is included: harness, helmet, climbing shoes and the boat to the cliffs. No need to bring your own kit.
Do you need experience to go climbing?
No. Operators such as Cat Ba Climbing run intro sessions for complete beginners. Routes from grade 4a are gentle walls with big holds, and in half a day you learn the basics and top out a 15-metre cliff.
How is Cat Ba different from Ha Long?
Cat Ba is about nature and the outdoors. Ha Long is about cruises and polished infrastructure. Cat Ba is quieter, cheaper and better for trekking and climbing. Lan Ha Bay off Cat Ba is the less-hyped version of Ha Long without the crowds. For the full comparison, see our Ha Long guide.
When is the best time to visit Cat Ba?
October to April is the dry season, ideal for climbing and trekking. Air temperatures sit at 18–25 °C with little rain. For beach days, May to August is warmer (water up to 28 °C), but expect humidity and short downpours.
How many days do you need for Cat Ba?
Two full days at least. One for climbing or DWS plus a kayak around Lan Ha, one for the national park, caves and beaches. If you want the trek, the cliffs and a cruise, give it three.
