With Vietpower Travel, exploring Tram Ton Pass Sapa—also known as O Quy Ho Pass or Heaven Gate Sapa—is more than a road trip; it’s a journey through the clouds. Stretching across the Hoang Lien Son Range, this is Vietnam’s highest mountain pass, connecting Lao Cai and Lai Chau in a breathtaking panorama of mist, forest, and valleys. Whether you’re a photographer, nature lover, or adventure traveler, Tram Ton offers a perfect blend of stunning scenery and cultural stories. Let Vietpower’s local expertise guide you through this unforgettable route in Northern Vietnam.
Tram Ton Pass (also known as O Quy Ho Pass) lies on National Highway 4D and is recognized as the highest mountain pass in Vietnam, rising between 1,900 and 2,035 meters above sea level. The pass connects Lao Cai and Lai Chau provinces, running through the majestic Hoang Lien Son Mountain Range, home to Mount Fansipan.
The pass serves as a symbolic administrative link between Lao Cai and Lai Chau, strengthening both tourism and logistics across the Northwest region.
From above, the pass winds gracefully through dense forests and deep valleys, forming one of the most scenic routes in Northern Vietnam. It is a must-see for travelers planning their next mountain adventure and exploring sapa where to go.
Tram Ton Pass is about 15–20 minutes (12–18 km) northwest of Sapa Town, accessible via Highway 4D. The road passes Silver Waterfall and Hoang Lien National Park, offering spectacular views of towering cliffs and evergreen forests.
Several sections feature well-maintained asphalt, making it one of the few mountain passes in Vietnam with smooth road conditions and minimal traffic. This ensures a safe, enjoyable drive for both cars and motorbikes.
Locals tell a touching story behind the name O Quy Ho. Long ago, a fairy fell in love with a mortal man, but fate kept them apart. Overcome with sorrow, she turned into a yellow bird, flying over the mountains and crying out her lover’s name — “O Quy Ho” — across the valleys.
These spiritual beliefs and love legends remain largely untouched by commercialization, allowing visitors to feel the authentic, spiritual charm of the region.
For the ethnic communities living nearby, the pass represents more than just a route — it embodies faith, love, and the timeless beauty of Vietnam’s highlands.
From February to July, Tram Ton Pass is a paradise for cloud hunters and sunrise seekers. Clear skies, mild temperatures, and blooming forests make it one of the best times to visit.
During early spring, morning dew glistening on sun-dried reeds and melting snow creates a short-lived but poetic landscape unique to Tram Ton Pass.
At dawn, clouds drift slowly below your feet, giving you the sensation of walking above the sky — a magical experience for photographers and dreamers alike.
From August to January, the pass turns into a tapestry of golden rice fields and misty valleys. In winter, the temperature drops dramatically, and visitors may witness rare scenes of frost or light snow covering the peaks — a breathtaking view seldom seen elsewhere in Vietnam.
Although the air is colder, the scenery becomes exceptionally calm and photogenic. Travelers should wear warm clothing and check the weather before departure to enjoy a smooth and memorable trip.
For travelers who enjoy independence and open-air adventure, renting a motorbike is an excellent choice to explore Tram Ton Pass.
Suggested Route: Start from the center of Sapa → follow Xuan Vien Street westward → pass Silver Waterfall (Thác Bạc) → climb the winding road of Highway 4D for another 6 km → reach Tram Ton Viewpoint (Heaven’s Gate) at the top of the pass.
If you prefer a comfortable and hassle-free ride, taking a taxi or booking a private car is the most convenient option.
Several reliable taxi services operate in Sapa, including Mai Linh Taxi (0214.3.833.833) and Green Taxi (0214.3.735.735). However, fares may vary depending on weather and demand.
If you prefer an organized experience, Vietpower Travel offers guided transfers and half-day tours that combine Tram Ton Pass with other top Sapa attractions.
Typical Itinerary (Half-Day Tour): Depart Sapa at 8:30 AM → stop at Silver Waterfall → explore Love Waterfall Trail → continue to Tram Ton Viewpoint for photos → optional visit to Rong May Glass Bridge → return to Sapa around 12:30 PM.
The Tram Ton Viewpoint, often called Heaven’s Gate, sits at the top of O Quy Ho Pass — about 18 km northwest of Sapa Town. From here, you can enjoy a sweeping view of Fansipan Peak, the Hoang Lien Son Mountain Range, and the misty valleys stretching far into Lai Chau Province.
Around the viewpoint, there are several photo corners decorated with ethnic-style huts and bamboo shelters, perfect for panoramic pictures. These small structures reflect the traditional highland lifestyle and provide a warm, authentic atmosphere.
Visitors can also find small tea stalls serving honey tea and grilled corn — ideal for a short rest while watching clouds drift below.
Located about 12 km from Sapa Town, Silver Waterfall (Thác Bạc) is one of the most iconic stops along the route to Tram Ton Pass. The waterfall cascades down 200 m from the mountain slopes, resembling a silver ribbon glittering in the sunlight — hence its name.
Visitors can climb a short flight of stairs for a closer view or continue toward the Love Waterfall trail. It’s a quick but memorable detour, perfect for photography or relaxation.
Nestled deep within the forest, Love Waterfall is a quieter and more romantic destination. The trail begins near the Tram Ton ranger station, just a few kilometers from Silver Waterfall. Along the path, you’ll walk under tall pines and hear birdsong echo through the valley.
Legend has it that a fairy once bathed here and fell in love with a mountain flute player. When her love was forbidden, she turned into a bird, forever calling his name — “O Quy Ho.” The story adds a poetic layer to this hidden gem.
The waterfall is about 100 m tall, and its pool below reflects the emerald color of the surrounding forest. It’s best visited in the morning or on weekdays for a quieter experience.
After crossing Tram Ton Pass and entering Lai Chau, continue 20–30 km along Highway 4D to reach Chu Va Viewpoint. This area opens to expansive views of terraced rice fields, winding valleys, and the mist-covered peaks of the Hoang Lien Son Range.
There are a few roadside cafés where you can stop for a drink while enjoying the view. During harvest season (August–October), the golden rice terraces here are a photographer’s dream.
Rising 3,147 m, Fansipan is the highest mountain in Vietnam and Indochina. Adventurers can choose to hike for two days from Tram Ton Ranger Station or take the modern cable car system, which shortens the trip to just 15 minutes.
The Fansipan cable car provides a fast, stunning aerial experience, offering a full view of Tram Ton Pass, Muong Hoa Valley, and surrounding peaks — an unforgettable highlight for any visitor.
At the summit, you’ll find a panoramic platform, a Buddhist pagoda complex, and coffee shops overlooking a sea of clouds.
For thrill-seekers, the Rong May Glass Bridge (Cầu Kính Rồng Mây) offers an extraordinary adventure. Standing at 2,200 m above sea level, the bridge extends 60 m from a cliffside, surrounded by clouds and mountain peaks.
This new attraction creates the illusion of walking in the sky, with a transparent glass floor that reveals the dizzying drop below — an exciting experience for bold travelers and photographers alike.
Safety belts are provided, and staff members ensure all visitors enjoy the activity safely. The site also includes a glass elevator, skywalk, and mountain zipline.
Tram Ton Pass sits at a high altitude where the weather can shift quickly — sunshine can turn into fog or light rain within minutes. Before your trip, check the Sapa weather forecast and avoid traveling during heavy rain or strong winds, especially if you plan to ride a motorbike.
Morning hours (7:00–10:00 AM) are ideal for clear visibility and stable light. During the foggy season (December–February), headlights and reflective clothing are useful for safety. If you’re driving yourself, slow down near sharp bends and sound your horn before each turn to alert oncoming vehicles.
Respecting nature and local communities helps protect Sapa’s unique charm. Always dispose of trash properly and avoid leaving food waste or plastic at viewpoints. Locals often sell snacks or souvenirs near the roadside — purchasing from them supports the local economy in a meaningful way.
Be considerate when taking photos of ethnic residents, particularly the H’Mong and Red Dao people. Ask politely before photographing them or their homes. Small gestures of respect go a long way toward creating a positive connection with the community.
