The Li River is famous in China and there is no more iconic location to see it than Yangshuo. The kayaking location starts from a near by village down stream from Yangshuo called Fuli. The stretch of the river takes you Down to Puyi with a stop at Liugong on the way to see the historic buildings and eat food. This is a nice alternative to riding on one of the rafts but be prepared to get wet!
The Kayaks are simple sit in closed cockpit designs, although they do have a few surf-ski type boats and some tandem touring kayaks as well. They will provide rudimentary flotation devices (PFD’s) and a basic wooden paddle, they do not have spray decks.
Cost is around 200rmb per person and there are many places in and around Yangshuo town where you can book kayaking.
