Vietnam Rong May Glass Bridge Faces Temporary Safety Closure Over Landslide Risks Starting October First

Vietnam's Rong May Glass Bridge on the O Quy Ho Pass will undergo a temporary operational suspension starting October 1, 2026, while geological authorities assess landslide risks linked to nearby construction.

Tourism and civil engineering authorities in Lai Chau Province, northern Vietnam, have announced a planned temporary operational suspension of the Rong May Glass Bridge (Cầu Kính Rồng Mây), effective October 1, 2026. The precautionary decision stems from concerns regarding a major construction project located directly behind the tourist site, where steep mountain terrain and heavy highland rainfall create potential landslide hazards.

Positioned along National Route 4D on the O Quy Ho Pass—approximately 16 kilometers from the mountain resort hub of Sa Pa—the glass skywalk offers panoramic views of the Hoang Lien Son mountain range. The Lai Chau Department of Culture, Sports and Tourism, alongside provincial engineering inspectors, is conducting a comprehensive safety review to evaluate slope stability, structural integrity, and risk mitigation measures before allowing normal visitor operations to resume.

Rong May Glass Bridge Operational & Economic Metrics

Operational Metric	Data Specification	Economic & Tourism Details
Official Opening Year	2019	Northern Vietnam's premier mountain adventure skywalk
Location & Access	O Quy Ho Pass, Lai Chau Province	16 km from Sa Pa via National Route 4D
Geographic Setting	Hoang Lien Son Mountain Range	Built on steep cliff faces overlooking mountain valleys

Foreign Passenger Share	80% International Tourists	Highly dependent on long-haul foreign tour packages
Annual Tourism Revenue	VND 200 billion (approx. US$7.6 million)	Core revenue generator for local accommodation and transit providers
Planned Closure Date	October 1, 2026	Temporary suspension for geological safety review
Pre-Closure Local Waiver	Free admission for Lai Chau residents	Entrance fees waived for local residents until October 1
Refund Guarantee	100% full refund	Complete refunds issued for pre-booked travel agency reservations

Construction Proximity & Geological Safety Review

The primary catalyst for the planned inspection is an active construction site positioned on the steep incline directly above and behind the glass bridge structure. In high-altitude alpine environments, earthmoving activities combined with monsoon rainwater saturation can alter soil cohesion, increasing slope instability risks.

Provincial engineering teams are assessing whether heavy excavation work has impacted ground stability around the glass elevator shaft and cantilevered glass bridge platform. Prior to October 1, normal operations continue, and local authorities are waiving entry fees for Lai Chau residents as a gesture of local community appreciation before technical inspections commence.

Impact on International Tour Itineraries

Because foreign travelers account for 80% of the site's annual 300,000 visitors, the temporary closure will require widespread itinerary adjustments across tour operators. Overseas travel packages connecting Hanoi, Sa Pa, Lai Chau, and Dien Bien are typically finalized 3 months in advance.

Travel agencies holding confirmed group bookings for October 1 onwards will receive 100% refunds for pre-paid admission tickets. However, tour operators are currently restructuring day-trip routes out of Sa Pa to incorporate alternative natural and cultural destinations across the northwest highlands.

Traveler Logistics Guide: Navigating Sa Pa & Northwest Vietnam Rerouting

Travelers planning autumn journeys through Sa Pa and Lai Chau should adjust mountain pass transit and sightseeing schedules accordingly.

1. Alternative Northwest Vietnam Mountain Experiences

• Fansipan Legend Cable Car (Sa Pa): Ascend Indochina's highest peak (3,143 meters) via the world-record three-rope cable car system departing from Sun World Fansipan Legend station in Sa Pa.
• Bach Long Glass Bridge (Moc Chau, Son La): For travelers prioritizing a glass skywalk experience, the 632-meter Bach Long Glass Bridge in Son La Province remains fully operational with verified safety certifications.
• Ma Pi Leng Pass (Ha Giang): Travelers exploring northern mountain passes can extend routes onto the Ha Giang Loop, taking in the dramatic Nho Que River canyon from Ma Pi Leng Pass.

2. O Quy Ho Pass Scenic Highway Transit

• Highway Safety (National Route 4D): While the Rong May Glass Bridge facility will close on October 1, the O Quy Ho Pass highway itself remains open to vehicular traffic. Motorcyclists and private driver charters can still access public scenic viewpoints along the pass connecting Sa Pa and Lai Chau.
• Transit Distance & Travel Times: The pass summit is reachable within 30 minutes from central Sa Pa by taxi or private car.

3. Ticket Refunds & Tour Adjustments

• Direct Booking Refunds: Independent travelers who purchased digital entry passes directly through online travel agencies (OTAs) should submit refund requests prior to October 1 to receive automatic credit card reversals.
• Tour Schedule Modifications: Contact your tour coordinator at least 14 days before departure to confirm updated day-trip replacements in Sa Pa, such as Cat Cat Village, Ta Phin Valley, or Heaven's Gate viewpoint.

Long-Term Destination Safety Framework

The proactive safety assessment at Rong May Glass Bridge underscores a broader regulatory shift toward strict adventure tourism governance in Vietnam. By prioritizing geological stability checks over short-term visitor revenue, civil authorities aim to ensure long-term structural safety and maintain international traveler confidence across Vietnam’s mountain tourism corridors.
