Chin Khoanh Ramp, also known as Nine Ramps or Chin Khoanh Pass, is a striking mountain road linking Pho Cao and Sung La communes in the Dong Van Karst Plateau, Ha Giang. With nine sharp, hairpin curves carved into steep limestone slopes, it offers a dramatic and unforgettable segment of the Ha Giang Loop for adventure travelers.

In this guide of Phieu Travel, you’ll discover the ramp’s exact location, the story behind its name, standout geological features, ideal travel seasons and cultural insights that make Chin Khoanh not just a route, but an experience worth remembering.

1. Introduction to the Chin Khoanh Ramp

This section takes you closer to what makes the Chin Khoanh Ramp so iconic. You’ll explore its exact location, its standout physical features and the reason behind the name “Nine Ramps”.

1.1 Location and Key Features of the Chin Khoanh Ramp

Chin Khoanh Ramp lies approximately 120 kilometers (74.5 miles) from Ha Giang City, along National Highway 4C – the main route through the Dong Van Karst Plateau. It connects Pho Cao and Sung La communes, features nine consecutive hairpin turns carved into limestone slopes.

The road is paved and generally well-maintained, but the sharp curves and steep incline make it one of the more technical segments of the Ha Giang Loop. Local travelers often say “even horses hesitate here,” and some call it the “vehicle test slope” for its ability to challenge both engines and riders – especially on the uphill climb.

1.2 Why is it Called the “Chin Khoanh Ramp”?

The name “Chin Khoanh” translates to “nine curves” – a reference to the ramp’s defining feature: nine tight switchbacks carved directly into the mountainside. Each bend offers a distinct view of the surrounding limestone cliffs and valleys. As you ascend or descend, the winding layout creates a rhythmic pattern, blending driving challenge with scenic discovery at every turn.

2. The Natural Scenery of the Chin Khoanh Ramp

From the upper curves of Chin Khoanh Pass, visitors can take in wide views of terraced ridges and calm valleys that unfold across the Dong Van Karst Plateau. The changing light throughout the day highlights the rugged shapes of the cliffs and surrounding hills.

Between October and December, the slopes bloom with buckwheat flowers in soft pinks and violets. These blossoms, carefully grown by local H’Mong women, line both sides of the ramp. For a small fee, travelers can pause to photograph the fields and meet the locals. The crisp mountain air carries a floral scent, adding to the quiet charm of this memorable highland stop.

3. Travel Tips for the Chin Khoanh Ramp

To make the most of your journey through Chin Khoanh Slope, it’s important to plan your transportation and timing carefully. The following sections offer practical tips on how to get there and when to visit for the best experience.

3.1 Transportation Options

To experience Chin Khoanh Pass at its best, you’ll want to ride a motorbike. It gives you the freedom to handle tight turns and steep ascents with ease. For these mountain roads, manual bikes with strong engines offer the best performance, especially when climbing. Semi-automatic models may feel underpowered, so choose a bike that’s well-maintained and built for rugged terrain.

From Ha Giang City, follow Nguyen Trai Street to National Highway 4C, then continue straight for about 6.7 kilometers (4.2 miles) to reach Chin Khoanh Ramp. This route is popular among travelers for its scenic views and steady incline.

Motorbike rentals are widely available in the city. Prices start from 180,000 VND/day for semi-automatic bikes and range from 550,000 to 600,000 VND/day for manual ones. Most providers even offer hotel delivery for extra convenience. Just remember to bring your ID, driver’s license and inspect the brakes, tires, engine,.. before setting off.

3.2 The Best Time to Visit

The ideal time to visit Chin Khoanh Ramp is between September and November, when Ha Giang enters its most scenic season. Clear skies and cool weather make for a pleasant journey, while the landscape transitions into golden rice fields and colorful floral blooms.

From October to December, the hillsides light up with buckwheat flowers in gentle hues of pink and purple. This seasonal bloom draws photographers and nature lovers alike, offering one of the most iconic backdrops on the Ha Giang Loop.

4. Important Tips When Visiting the Chin Khoanh Slope

Conquering Chin Khoanh Ramp is both thrilling and demanding. To stay safe and make the most of your adventure, keep these practical tips in mind:

• Choose the right motorbike: Not every motorbike can handle the steep, winding ascent. Opt for a manual bike with a strong engine, especially if you plan to ride uphill. Semi-automatic models often struggle on this slope, and automatic bikes are not recommended.
• Go with an easy rider (if needed): If you’re new to mountainous roads or feel unsure, consider hiring an easy rider. These local drivers know every curve and elevation change and can guide you safely through one of Ha Giang’s trickiest passes.
• Check weather conditions in advance: Chin Khoanh sits at a high altitude and is often shrouded in mist or clouds, especially in the early morning or late afternoon. Reduced visibility can make driving dangerous, so avoid visiting during rainy or foggy periods, and always check the forecast.
• Avoid night rides: This road is not recommended after dark. Limited lighting, narrow turns, and unpredictable mountain weather can pose real risks. Plan your route to pass Chin Khoanh during daylight hours for better control and stunning views.
• Inspect your vehicle before the climb: Before hitting the road, check your brakes, tires and headlights. If your bike isn’t in top condition, even experienced riders might struggle. Renting from a reputable shop and doing a quick inspection could save you from trouble halfway up.

5. Legends and Culture Associated with the Chin Khoanh Pass

Locals believe that any couple who conquers Chin Khoanh Slope together will stay together for life. No one knows exactly how the legend began, but it continues to inspire young travelers today. Many pairs visit the slope not only for the challenge but to mark a memorable milestone. Some even choose to take wedding photos here, turning the climb into a celebration of commitment. Over time, the ramp has become a quiet cultural symbol – one of love, resilience and shared adventure.
