The terraces were built by the Hani people over at least thirteen centuries, cutting the slopes of the Ailao Mountains into thousands of individual fields that follow the contours of the land. The system depends on a forest above the village, a village in the middle and terraces below, so that water and nutrients pass through the whole system. That arrangement was recognized as a UNESCO World Heritage cultural landscape in 2013.
Why the season matters
The terraces are flooded from roughly November to April, which turns each field into a mirror. At sunrise and sunset the water reflects the sky and the light, and the whole mountainside shifts from grey to pink to gold within half an hour. From May the fields are planted and turn green, and from September they ripen to yellow before harvesting. Photographers come for the flooding season, and the most famous viewpoints are at Duoyishu for sunrise and Laohuzui for sunset.
The villages
The Hani villages among the terraces are built of mud brick with mushroom-shaped roofs in the older houses, and the communities still farm the terraces by hand. Weekly markets rotate between villages and are a good place to see Yi and Hani dress and produce.
Practical notes
Yuanyang is in the far south of Yunnan, about five to six hours by road from Kunming, and the mountain roads are winding. Allow at least two nights to catch both a sunrise and a sunset, since cloud often spoils one. Sunrise means leaving the guesthouse around 5:30 a.m. Bring a headlamp, warm clothes, and a tripod if you plan to photograph. Viewpoint access usually requires a combined ticket. The best months are December through March, when the air is clearest.
