At the end of autumn and the beginning of winter, when the first chilly winds sweep across the borderlands, the white mustard flowers begin to bloom, blanketing the mountains and forests of Moc Chau. The skies and lands of the Northwest don a heavy winter coat, and the towering mountains seem gentler in their majestic, captivating form.
Conquer the Legendary Thung Khe Pass
On a winter journey to the Northwest from Hanoi, travelers will face a challenging stretch of road as they navigate the chilly air and mist swirling around the steep bends of Cun Pass. The path is winding and treacherous, with sharp turns at every corner. Halfway up Cun Pass, there's a small tea stall run by the Thai ethnic people, where visitors can sample local specialties of the Northwest such as pork, grilled rice, and more. It’s a perfect spot to take a break, sip on hot tea amidst the cool air, and admire the towering limestone cliffs against the vast sky of the Northwest.

After a brief rest, travelers can continue their journey to conquer Thung Khe Pass in Hoa Binh, one of the most legendary mountain passes in domestic tourism. Thung Khe Pass is nestled between towering mountains, with a sheer rock wall on one side and a deep abyss on the other. The pass captivates visitors with its mystical beauty, raw nature, and grandeur, offering a poetic landscape that rivals any tourist attraction in Vietnam.
Mo Chau - A Paradise Between Heaven and Earth
From Thung Khe Pass, travelers can head straight to Moc Chau, often referred to as a paradise nestled between the sky and earth. This poetic name comes from the fact that Moc Chau sits at an altitude of around 1,050 meters, making it one of the most beautiful plateaus in Vietnam.
The journey to explore Moc Chau will take visitors to Ba Phach, a place known as the paradise of white mustard flowers. To witness the vast sea of white in the mustard flower valley, travelers must navigate through rugged dirt roads and venture deep into the ethnic villages. It is here that the endless fields of white mustard flowers stretch as far as the eye can see, spanning from one mountain peak to the next valley.

In addition, when visiting the white mustard flower fields in Moc Chau, travelers can also explore famous landmarks in this Son La tourism region, such as the Bản Áng pine forest, the Rơi cave, the Dải Yếm waterfall, and the Moc Chau dairy farm. In the evening, visitors can savor the local specialties of this highland region, including stream fish, wild vegetables, mustard greens, grilled veal, hill chicken, cơm lam, fresh salmon, and smoked buffalo meat.
Cloud Hunting in Ta Xua
It would be a missed opportunity not to visit Ta Xua for cloud hunting when in Moc Chau. The best time for this adventure is from November to March, particularly during the winter months in the Northwest, when clouds layer over the villages, drifting above the mountain peaks both day and night. This marks the start of the cloud hunting season in Ta Xua.
