About 350 km of mountain road across the Đồng Văn karst plateau, right up against the Chinese border. You ride on the back of a bike with a local easy rider while grey limestone peaks crowd the road, corn grows in pockets of soil between the rocks and H’Mông kids wave from doorways. Then the road drops away into the Nho Quế canyon. Nights are homestay dinners with your riders and the group, usually with a round of corn wine.
Your first big view of the plateau, with the two rounded Fairy Twin Mountains in the valley below.
A cool, green stretch of pines between all the bare rock.
Switchbacks zig-zagging up a mountainside. The classic photo stop.
The stone-and-wood mansion of the H’Mông “king”, built in the early 1900s.
A huge flag near Vietnam’s northernmost point. In Oct–Nov the fields around it turn pink with buckwheat flowers.
Old tile-roofed houses under the cliffs. Busiest and most colourful on Sunday market day.
A road cut into the cliff above a jade-green river. Most loops add a boat ride through Tu Sản canyon.
A quiet valley village with a waterfall for a swim on the way back.
The 3-day loop works, but the riding days get long and Du Già usually drops off. Skip anything shorter: it’s mostly time in the saddle.
Five days means shorter rides, a market day in Đồng Văn or Mèo Vạc, and more time at Du Già.
