The S-Shape Rice Terraces (Cánh đồng lúa hình chữ S) is the single most photographed view in Pù Luông Nature Reserve - an S-shaped road that winds through the rice fields of Don Village (Bản Đôn), seen from a hillside lookout above. The S comes from the curve of the road itself as it threads across the valley floor, not from the shape of the terraces - the surrounding paddies and limestone slopes form the landscape around the curve, and it's the combination of the winding road, the stepped fields on either side, and the framing hills that makes the view so distinctive from above.
The fields themselves are part of the working farmland of Don Village and are planted, flooded, and harvested on the same calendar as the other rice fields in the valley. The viewpoint above is a roadside lookout on the route into the reserve, and is the natural sunset stop for travellers based in Don Village.
