The longest day - leave by 7am and keep stops short. Quan Ba Heaven Gate and the Twin Mountains first, lunch in Yen Minh, then Tham Ma Pass and the Hmong King Palace (7:30am-5pm, 20,000-25,000 VND). Reach Lung Cu Flag Tower (8am-5pm, 25,000 VND) before it closes and sleep in Lo Lo Chai, the farthest point of the loop - try a night in a traditional rammed-earth Lo Lo house. Don't ride the passes after about 7pm.
Đồng Văn Old TownMã Pí Lèng PassNho Quế River
The best day of the loop. Dong Van Old Town in the morning - if it's Sunday, the market is busiest 7-10am. Then Ma Pi Leng Pass at your own pace, stopping at every viewpoint. For the Nho Que boat, don't search "Nho Que River" on Google Maps (it sends you toward Cao Bang) - search "Tu San" and follow the main road, not forest tracks. The boat is about 150,000 VND per person including the shuttle down to the pier (2026); aim to be there by 4pm. Night in Meo Vac.

Early start - the Meo Vac to Mau Due stretch has a lot of potholes. Lunch in Du Gia, a quiet Tay village in a river valley, and a swim at Du Gia Waterfall if the weather allows. Back in Ha Giang by late afternoon for the night bus to Hanoi.
