The Rong May Glass Bridge is a glass-floored walkway fixed to a cliff at the top of the O Quy Ho Pass, about 17 km from Sapa town in Lai Chau Province. You reach it through a tunnel and a lift in a steel tower, and the operator’s sign gives 2,333 m above sea level and 758 m above the gorge. Allow about two hours on site.
It is not a bridge between two cliffs, and it is not in Sapa town. It is a private attraction with a ticket, paid rides and a view that depends entirely on the cloud, so what you see on the day can be very different from the photos.

Your own car and a licensed guide who comes up to the glass with you. Every ticket is covered in the price.

Most travellers simply call it the Sapa glass bridge, and some booking sites use the name Cloud Dragon Skywalk. It opened in 2019 and is run by a private company, Hoang Lien Son Group.
Think of it as a viewing walkway, not a crossing. The floor is clear glass, the sides are glass panes with a thick gold-coloured handrail, and it follows the mountainside in long straight sections, with the valley and Highway 4D far below you.
The numbers on the operator’s sign
| Item | Operator’s sign |
|---|---|
| Height above sea level | 2,333 m |
| Height above the gorge | 758 m |
| Total length of glass | 139 m |
| Width of the deck | 1.5 m |
| Glass | 3 tempered layers and 4 film layers, 33.04 mm in total |
Other sources give very different numbers, including a far longer bridge and a lift anywhere from 70 m to 300 m tall. Because they disagree, we quote the sign on site and nothing else.
How a visit works, step by step
You arrive at the gate on Highway 4D, may switch to the site’s shuttle for the last stretch of road, then walk through a tunnel of about 70 m inside the mountain, lit with coloured hoops. A glass-sided lift then takes you up a tall steel lattice tower, about 30 people at a time.
At the top, a walkway roofed in blue panels leads to the glass. Staff hand out shoe covers to protect the surface, and you walk out at your own pace. There are stairs and a long walkway, so it is not a flat stroll, but there is no forest climb.
Around the bridge you will find snack bars, cafes, a hotel and paid rides, including a swing, a zipline and a long log walk. Those are priced per ride and sit outside the entry ticket.
Tickets at a glance
The operator’s price board lists the lift ticket at 500,000 VND (~$19) for an adult and 300,000 VND (~$12) for a child from 1 m to under 1.4 m, with children under 1 m free. Each ride costs 150,000 VND (~$6). The board also says tickets are valid only on the day booked and are not refundable once issued, which matters on a cloudy morning.
Why the cloud decides your visit
At this height the view can change in minutes. On a clear day you look across the Hoang Lien range and down to the road. In thick cloud you can stand on the glass and see white in every direction, and visitors’ reviews describe both.
The Sapa side of the pass is often in cloud when the far side is clearer, so the sky in town tells you little. The season in short: Clear views are never guaranteed at 2,333 m. The drier months run from about September to April, though winter brings cold and thick cloud on some days. From May to September expect showers, often in the afternoon.
Is it open at the moment?
In September 2026 the operator announced a stop from 1 October because of construction next door, then said it would run from 1 October until further notice. A provincial inspection followed, and we had seen no published result or new closure notice by early November 2026. We check before every tour and tell you at once if anything changes.
Two ways to include it in your Sapa days
The half day keeps to the pass. The full day adds a Hmong village in the morning and lunch on the road.

Is the Rong May Glass Bridge the same as the Sapa glass bridge?
Yes. It is one place, and booking sites sometimes call it the Cloud Dragon Skywalk. It stands in Lai Chau Province at the top of the O Quy Ho Pass, about 30 minutes by car from Sapa town.
How long do you need there?
About two hours is comfortable, including the tunnel, the lift, any wait, the walk along the glass and some time for photos. A ride or a long coffee adds to that.
Do you have to walk on the glass?
No. If heights are a problem you can stay on the solid deck, or step a little way out and turn back. Nobody checks that you finish the walk.
Can you go without a tour?
Yes. A taxi from Sapa and a ticket at the gate will do it, and it costs far less than a private tour. A private tour makes sense when you want a guide with you or more stops on the same road.
