The biggest ethnic market in the Lao Cai province, where you will find buffaloes, horses, blacksmiths, saddlers, but also traditional medicine doctors, with their thousands of mountain herbs and plants, and lots of traditional clothes and local artefacts. Several groups of deep-coloured Hmong are found there, as well as Dao, Tay, Nung, and Phu La. Make sure to arrive before 9 a.m., the market ends at about 12: 30. Sleeping in Bac Hà, on the Saturday offers an opportunity to watch the preparations for the market and the successive waves of villagers going there. Tasting the local corn spirit is a must, but be prudent, it may be up to 55° proof!
