Bach Long – The world’s longest glass bridge
The Bach Long Glass Bridge, or “White Dragon” in Vietnamese, is the longest glass-bottom bridge in the world. It stretches more than 630 meters across a deep valley in Moc Chau, with part of the walkway built directly into the cliff and the rest suspended 150 meters above the ground. It’s one of Vietnam’s most striking man-made structures—and an experience that’s both scenic and slightly nerve-wracking if you don’t love heights.
The bridge opened in 2022 and quickly earned recognition from Guinness World Records. It’s located inside the Moc Chau Island tourism complex, a resort-style area in Son La Province that combines mountain views, engineered attractions, and family-friendly activities. The project took two years to build and was designed to bring more travelers to this quiet region in Vietnam’s northwest.
The walkway is made from triple-layered tempered glass imported from France, with each panel 40mm thick. Despite how it looks underfoot, it’s been tested to hold up to 450 people at once and meets international safety standards. You cross one way along the glass floor, with open views of the forest below and limestone cliffs around you. You’re not walking across this bridge to get somewhere. You’re doing it for the views, the thrill, and maybe to push past a fear of heights. It’s exciting, a little nerve-wracking, and designed to be a highlight for anyone visiting Moc Chau.
Is the Bach Long Glass Bridge safe?
Yes, the Bach Long Glass Bridge is built with safety in mind, even if it might not feel like it when you’re standing on see-through glass 150 meters above the ground.
The entire walkway is made from three layers of tempered glass, each 40mm thick and imported from France. The structure has a safety factor six times higher than standard requirements, and before opening, it was tested by driving a full-size SUV across the surface.
The bridge can hold up to 450 people at a time, but staff limit the number of visitors to make sure it never gets overcrowded. The suspension cables are made in Korea, and the design meets safety certifications from both Japan and Vietnam.
If you’re nervous about walking on glass, there’s a solid white strip on each side of the bridge. Many people use this to stay close to the edge while holding the railing. The glass is strong and secure—but if you have a fear of heights, the experience can still feel intense.

Highlights and Things to do
The Bach Long Glass Bridge is the main attraction, but the surrounding Moc Chau Island complex includes several other activities. Some are included in the ticket price, while others require an extra fee. Here’s a quick overview of what else you can see and do.
1. Glass Bridge Walk
The bridge walk starts with a section built into the cliffside, then extends across a deep valley between two mountain peaks. The entire route is about 632 meters long and made entirely of clear glass, offering open views of the forests and limestone below.
The walk is one-way, ending at the Holy Bird Cave. After that, you’ll need to head down into the valley to return. You can walk down a long stair path or pay for the Moc Chau Space Elevator for a faster ride back to the lower level.
2. Holy Bird Cave (Chim Than Cave)
At the end of the bridge, you’ll reach a small limestone cave known as Chim Than, or “Holy Bird Cave.” It’s a short stop with colorful lighting and some interesting formations—not very large, but a nice way to end the bridge walk.
The cave is linked to a local legend about a divine bird that once lived in the area, though most visitors come more for the novelty than for the folklore.
3. Zipline Sky Tour
If you want a bit more adrenaline, you can ride the zipline that stretches over 600 meters between two mountain slopes. The ride is fast but scenic, offering a different perspective over the surrounding forest.
This attraction is not included in the main ticket and costs 180,000 VND per person.
4. Moc Chau Space Elevator
This modern glass elevator is designed like a spaceship and connects the lower resort level with the bridge access point. You can use it instead of walking up or down the stairs.
The ride takes less than a minute and costs 80,000 VND. It’s optional but useful, especially if you’re visiting with kids or want to avoid steep walks.
5. Water Gun Boats
A playful option for kids and families: these small round boats float on a shallow lake, and each one comes with a water cannon. It’s mostly fun during hot weather or with groups.
This activity costs 80,000 VND per boat.
6. Go-Kart Racing
There’s a small but well-paved go-kart track near the lower part of the park. The price depends on the number of laps or ride time, usually ranging from 150,000 to 300,000 VND.
It’s not huge but can be a fun diversion if you’re spending more time in the complex.
7. Rainbow Airslide
This 250-meter slide runs down a hillside in wide rainbow-colored lanes. You sit in a soft inflatable ring and glide down at a good speed. The ride is smooth, fun, and especially popular with kids and families.
The cost is 50,000 VND, and it’s one of the more affordable add-ons.
8. Children’s play area
This is a small playground zone with various games designed for young children. It’s basic but useful if you’re traveling with kids who need a break from the walking.
Where is the Bach Long Glass Bridge located?
The Bach Long Glass Bridge is located in Moc Chau District, part of Son La Province in northwest Vietnam. It’s about 200 kilometers from Hanoi and around 75 kilometers from Mai Chau, making it a possible stop on a longer trip through the region.
Moc Chau is known for its cool climate, scenic tea plantations, pine forests, and ethnic minority villages. While still relatively quiet compared to places like Sapa or Ninh Binh, it’s become more popular in recent years—especially with the opening of attractions like this bridge.
How to get to the Bach Long Glass Bridge
To reach the bridge, you’ll first need to get to Moc Chau Town, then continue about 10 kilometers to the entrance of the Moc Chau Island tourism complex.
Custom trip with the Glass Bridge included
Want to visit Bach Long Bridge and more? We can create a full itinerary from Hanoi with hidden waterfalls, tea hills, and time to enjoy the glass bridge without rushing.
From Hanoi to Moc Chau
The most comfortable and efficient way to travel from Hanoi is by limousine bus. These are small 9-seat vans with air-conditioning and reclining seats. The ride takes around 4.5 to 5 hours depending on traffic and departure point. Some services offer hotel pickup in Hanoi’s Old Quarter.
You can also take a sleeper bus, but for this route, it’s less ideal—most are designed for overnight travel and may not be as comfortable during the day. Another option is to hire a private car with driver, which is convenient if you’re traveling in a group or want more flexibility to stop along the way.
We’ve created a separate guide with all transport options, booking tips, and travel times — you can read it here:
From Hanoi to Moc Chau
From Moc Chau Town to the Bridge
Once you arrive in Moc Chau, getting to the bridge is easy. The Bach Long Glass Bridge is located about 10 kilometers from the town center.
- Motorbike rental is a good option if you have riding experience and a valid license. It gives you flexibility to visit other nearby spots as well.
- Taxi is a simple and convenient choice, especially for short visits. Be sure to agree on the price in advance, including waiting time and the return journey.
- If you’ve booked a private car or tour, this part will usually be included.
Inside the Moc Chau Island complex, there are electric shuttles to move between attractions, so you won’t need to walk long distances once you’re there.
Can you visit the Glass Bridge on a day trip from Hanoi?
In theory, yes—you can visit the Bach Long Glass Bridge on a day trip from Hanoi. But in practice, it’s a long and tiring journey.
The drive takes around 4.5 to 5 hours each way, depending on traffic. That means you’ll spend close to 10 hours on the road for what might only be a 1–2 hour visit, especially if you’re only planning to walk the bridge and skip the extra activities.
If you’re curious about the bridge and already traveling through this part of Vietnam, it’s much better to spend at least one night in Moc Chau. That way, you can explore the surrounding area, enjoy the cooler climate, and visit other places like tea hills, waterfalls, or ethnic minority villages.
The bridge is part of a larger complex, and the region itself is worth taking your time to explore—not just rushing in and out for one attraction.
Is it worth visiting the Bach Long Glass Bridge?
That depends on your travel style and expectations.
The Bach Long Glass Bridge is genuinely impressive in terms of engineering. It holds an official world record, and the scale and setting make it a unique place to visit. If you’re into architecture, thrill-based attractions, or simply enjoy unusual viewpoints, it delivers what it promises.
However, the ticket prices are high by Vietnam standards, especially once you factor in add-ons like the elevator, zipline, or water-based activities. The overall experience is well-organized, but some parts of the park feel more commercial than scenic. If you’re on a tight budget or prefer natural, low-cost travel, this might not feel worth the price.
The bridge is also not ideal for people with a strong fear of heights. While it’s safe and well-built, the clear glass underfoot can be overwhelming for some.
That said, if you’re already in Moc Chau—or planning to be—and looking for something unusual and exciting, the bridge is a fun and memorable stop.
What else to do around Moc Chau
Moc Chau isn’t just about the glass bridge. This highland district in northwest Vietnam is known for its cool climate, peaceful landscapes, and mix of natural and cultural sights. If you decide to stay longer than a quick visit to the bridge, there’s plenty to explore.
Here are some highlights nearby:
- Pha Luong Peak – One of the region’s top trekking spots, right near the Laos border. The hike is challenging but rewards you with wide mountain views and a sense of remoteness.
- Dai Yem Waterfall – A multi-tiered waterfall surrounded by forest, best visited in the rainy season when water flow is strongest. The area is also good for a short walk and photos.
- Tea plantations – Moc Chau is famous for its rolling green tea fields. Some areas allow visitors to walk through the plantations or stop for tea tasting.
- Ethnic minority villages – The region is home to Thai and Hmong communities. Staying in a local homestay or visiting a village gives you a closer look at traditional crafts and daily life.
