A curtain of white water spread across a whole cliff — wide, even and theatrical, with rainbows in the spray when the sun angle is right.
Rainbow hour — When sun clears the valley wall the spray throws rainbows right across the falls — aim mid-morning.
Warm valley light — Low evening sun warms the rock face while the falls stay cool white — a natural colour contrast.
Full curtain — The falls are widest within a couple of days of rain; the whole cliff pours.
The Chuandong River Waterfall is one of Guizhou's most satisfying waterfalls to photograph precisely because of its shape. Rather than dropping in a single narrow ribbon, the river spreads across a wide, even rock face and falls as a broad curtain — tens of metres across, white and even, like stage scenery. The valley in front is open and green, the pool below is turquoise in clear weather, and a path lets you get close enough that the spray is part of the experience.
The two pictures to aim for are opposites. The first is fast and colourful: when the sun gets high enough, the mist hanging in front of the curtain catches the light and you get rainbows arcing across the falls — shoot them with the polariser backed off so the colour stays strong. The second is slow and quiet: in the late afternoon the valley goes into shade, and a one or two second exposure turns the curtain into soft, foggy silk against the dark rock, with the green pool stretched out in front.
Mar-May. Full flow and the most frequent rainbows.
Jun-Aug. Biggest curtain and boldest spray; humid haze softens backgrounds.
Sep-Nov. Clean air, golden valley light, reliable flow.
Dec-Feb. Lower water but quiet trails and crisp detail.

We plan the day around both windows — rainbows in the morning, silk in the afternoon — and get you back to the falls for the best light.
