Dong Van Karst Plateau Geopark

Transport directions coming soon.

Why It Matters

• UNESCO Global Geopark since 2010 — recognised for exceptional geological, ecological, and cultural significance
• Limestone formations 500 million years old — among the oldest exposed karst on Earth
• 17 ethnic minority groups call the plateau home: Hmong, Lo Lo, Pu Peo, Giay, Tay, and others
• The backdrop to the entire Ha Giang Loop — every pass, valley, and village is inside the geopark boundary

Key Sites Within the Geopark

• Ma Pi Leng Pass — the most dramatic section of the plateau edge
• Dong Van Old Quarter — 19th-century trading town inside the geopark
• Lung Cu Flag Tower — the plateau's northernmost landmark
• Tu San Canyon — the deepest canyon in Indochina, carved by the Nho Que River
• Sung La Valley — hidden valley with buckwheat fields and traditional clay-wall houses

Practical Information

• Entrance fee: Free (individual sites may charge separately)
• Access: Via Ha Giang Loop (QL4C highway) from Ha Giang City
• Best season: Oct–Nov (buckwheat flowers + harvest), Feb (canola flowers), Jan–Mar (dry and clear)

Tips

• The geopark is not a single site — it is the entire landscape you ride through on the loop
• The Dong Van Geopark Museum in Dong Van town has good English-language exhibits on geology and culture
• Allow 3–4 days minimum to explore the plateau properly by motorbike
