What it is
Cap Treo Nu Hoang — the Queen Cable Car — connects the base station in Ha Long City to the peak of Ba Deo Mountain, and it's one of the longest ropeways in Vietnam (베트남 / 越南 / ベトナム) at roughly 2 km per stretch. Opened in 2016 as part of the Sun World Ha Long Complex (now called Sun World Halong Complex), the system was built by Doppelmayr, the same Austrian company behind cable cars in the Alps. Each cabin holds up to 230 passengers, which makes it less of a gondola and more of a floating bus.
The top station sits at around 215 meters above sea level. That doesn't sound like much on paper, but when you're looking out over Ha Long Bay and the sprawl of Bai Chay below, the elevation does its job.
Why travelers go
Most people visiting Ha Long Bay (하롱베이 / 下龙湾 / ハロン湾) spend their time on cruise boats, which is fair — that's the main draw. But if you have a half-day gap before or after a cruise, or you're staying overnight in Ha Long City, Cap Treo Nu Hoang gives you a completely different angle on the bay. You see the karsts from above rather than weaving between them at water level.
The cable car is also the entry point to Sun World's amusement park at the top, which includes a Japanese garden, a wax museum, and some carnival rides. It's not everyone's thing, but if you're traveling with kids or just want something to do beyond boat trips, it fills a solid three to four hours.
Best time to visit
October through December is the sweet spot. The air is cooler, humidity drops, and you get clearer views from the top. Summer months (June through August) bring haze and afternoon thunderstorms — you might ride up into a cloud and see nothing. The cable car does close during heavy winds or storms, so check conditions if you're visiting during typhoon season (roughly September to November, though October is usually fine).
Weekday mornings are best for short queues. Weekend afternoons, especially during Vietnamese holidays and around Tet, the wait can stretch past 30 minutes.
How to get there from Hanoi
Ha Long City is about 160 km east of Hanoi. You have a few options:
- Bus: Shuttles from My Dinh or Gia Lam bus stations run frequently. The trip takes around 3.5 to 4 hours and costs 100,000–150,000 VND one way. Kumho Viet Thanh and Phuc Xuyen are reliable operators.
- Private car/taxi: Around 2.5 to 3 hours depending on traffic. A one-way transfer runs 1,200,000–1,500,000 VND for a sedan.
- Limousine van: Several companies run nine-seat vans with hotel pickup in Hanoi (하노이 / 河内 / ハノイ)'s Old Quarter. Expect 200,000–350,000 VND per person, door to door.
Once in Ha Long City, the cable car station is at Sun World Ha Long Complex on Ha Long Road in Bai Chay Ward. A taxi from the bus station costs about 50,000–80,000 VND.

What to do
Ride the cable car (obviously)
The ride itself takes about 5 minutes each way. Grab a spot near the glass walls — the view of Ha Long Bay to the south and the city's coastline is the whole point. On a clear day, you can pick out individual islands.
Walk the Japanese garden
At the summit, the Zen garden area is surprisingly well-maintained: koi ponds, bonsai, raked gravel paths. It's quiet compared to the rest of the amusement park, and it makes for a decent 20-minute wander. Best light for photos is before 10 a.m.
Hit the observation deck
Separate from the garden, there's a viewing platform near the top station. Bring binoculars if you have them — you can trace the outlines of the karst formations across the bay. This is the spot where Ha Long Bay actually looks like the postcard version, minus the boat exhaust.
Check out the amusement park
Sun World's rides are tame by international standards, but kids love them. The indoor wax museum has decent figures of Vietnamese historical and cultural figures alongside international celebrities. Expect to spend 1.5 to 2 hours if you explore everything.
Take the alpine coaster down
If the alpine coaster is running (it's seasonal and weather-dependent), it's a fun 5-minute ride winding down part of the hillside. Separate ticket, usually around 100,000–150,000 VND.
Tickets and costs
As of early 2025, the combo ticket for the cable car plus amusement park access runs around 500,000–600,000 VND for adults and 350,000–400,000 VND for children (1–1.3 m tall). Prices shift seasonally and Sun World occasionally bundles promotions. Buy tickets at the counter or online through the Sun World app — online booking sometimes saves 10–15%.
Where to eat nearby
Bai Chay's waterfront strip has dozens of seafood restaurants, many of them tourist traps with inflated prices. A better bet:
- Cho Ha Long (Ha Long Market): Head to the second floor of the market for "bun rieu" — crab noodle soup done the northern way, tangy and loaded with tomato broth. A bowl runs 35,000–50,000 VND. You'll also find solid "cha gio" (fried spring rolls) at the market stalls.
- Seafood on Vuon Dao Street: A few locally-run places here grill clams, mantis shrimp, and squid over charcoal. Prices are lower than the waterfront — expect 300,000–500,000 VND for a proper seafood spread for two.
If you want a proper sit-down Vietnamese coffee before the ride, look for any small cafe on Ha Long Road rather than the branded shops inside the complex.

Where to stay
- Budget: Guesthouses and mini-hotels in Bai Chay Ward start at 300,000–500,000 VND per night. Basic but clean.
- Mid-range: Three-star hotels along Ha Long Road go for 600,000–1,200,000 VND. Many include breakfast and bay views from upper floors.
- Splurge: A few international-brand resorts sit on the Bai Chay coastline. Expect 2,000,000–4,000,000 VND per night.
Practical tips locals would tell you
- Bring a light jacket. It's noticeably cooler and windier at the top, even in summer.
- Eat before you go up. Food inside Sun World is overpriced theme-park fare. Fill up at the market first.
- Don't plan it on cruise departure day. If your Ha Long Bay cruise leaves at noon, you won't have time. Do the cable car the day before or after.
- Charge your phone. There's no charging station at the top, and you'll burn battery on photos.
Common mistakes to avoid
- Going in the afternoon on a hot day. Haze kills visibility. Morning rides are sharper.
- Buying tickets from touts outside the complex. Stick to the official counter or app.
- Skipping the garden and only doing rides. The Japanese garden is the most pleasant part of the summit — don't blow past it.
- Assuming the cable car is the whole visit. Budget at least 3 hours for the round trip plus exploring the top. Rushing through in an hour wastes the ticket price.
Practical notes
Cap Treo Nu Hoang works best as a half-day addition to a Ha Long Bay trip, not a standalone destination. Pair it with a morning at the bay or an afternoon exploring Ha Long City's waterfront. If you're heading onward to Ninh Binh (닌빈 / 宁平 / ニンビン) or Cat Ba after your cruise, this slots in neatly on your transit day.
