Tham Ma Slope – The Legendary Pass Amidst the Rocky Plateau of Ha Giang

If you’re looking for a destination that blends raw mountain beauty, rich cultural depth, and a sense of adventure, then Tham Ma Slope is a name you can’t overlook on your journey through Ha Giang.

As an essential part of the legendary Happiness Road that winds through the Dong Van Karst Plateau, Tham Ma Slope has become a lasting symbol of Vietnam’s northernmost frontier.

What is Tham Ma Slope, and why does it captivate travelers?

Tham Ma Slope is a dramatic mountain pass located on National Highway 4C, linking Yen Minh town to Sung La valley in the UNESCO-designated Dong Van Karst Plateau Geopark. The name “Tham Ma” literally means “horse testing slope,” and it originates from a traditional practice in which locals tested the strength of horses—only those capable of climbing the steep incline were kept to carry goods across the rugged terrain.

Today, Tham Ma is no longer just a steep section of road—it’s a cultural and visual landmark. With nine sharp switchbacks curving along sheer cliffs, this slope offers an exhilarating challenge for motorbike riders, photographers, and nature lovers alike.

Marvel at the breathtaking views and legendary curves

Tham Ma Slope makes a lasting impression from the very first glance. The road snakes like a ribbon across gray limestone cliffs, bordered by deep valleys and layers of jagged mountains stretching into the horizon. On misty mornings, drifting clouds wind through each curve, creating a mystical, almost cinematic landscape.

From elevated viewpoints along the slope, travelers can enjoy sweeping vistas of Sung La Valley, charming H’mong villages nestled in the hills, and—if you’re lucky—catch heartwarming scenes of local children carrying their siblings while picking wild vegetables on the hillsides. These are not just sights, but glimpses into the soul of northern Vietnam.

Tham Ma Slope through the seasons – A new experience every time

One of the unique charms of Tham Ma Slope is its ever-changing appearance with the seasons, offering visitors a fresh experience no matter when they arrive.

• Spring (Feb – Apr): Cherry and plum blossoms burst into bloom, covering the hills in soft whites and pinks. Fresh mountain air mixes with the sound of H’mong flutes and laughter in spring markets, adding a poetic charm to the region.

• Summer (May – Aug): Lush greenery and comfortable weather make this an ideal time for trekking, hiking, or even camping near the forested slopes.

• Autumn (Sep – Oct): Golden rice fields ripple in the wind, while vibrant buckwheat flowers begin to bloom. The slope transforms into a painter’s palette, where yellow and pink weave across the valleys.

• Winter (Nov – Jan): Dense fog drapes the mountains, temperatures drop, and the atmosphere turns still and contemplative. It’s a perfect time for those seeking solitude and poetic scenery.
