Maletsunyane Falls is a single column of water 192 metres high dropping into a basalt gorge in the highlands of Lesotho, and the river that makes it gives no warning at all. Up on the plateau, around 2,200 metres, the Maletsunyane loops in wide, lazy bends across open grassland. Following it on foot or on horseback, past stone huts and herd boys and grazing animals, is the quietest way to understand how ordinary the water looks minutes before it disappears. Then the grass simply stops, and the river goes over the lip unbroken. The ponies are the way to get about here. Sure-footed Basotho mountain ponies carry you along the paths between the villages and the gorge, led by riders in the heavy blankets that are still everyday dress up here. Horses remain real transport in these mountains rather than something arranged for visitors.
Most people meet the water by going over the edge beside it. You step off a few metres from the falling column and hang there turning against wet basalt for several minutes before your boots find the gorge floor — the longest commercial rope descent of its kind anywhere. On the way down you share the gorge with bearded and Cape vultures, two of the rarest large birds in southern Africa, which nest and roost on these same walls. They ride the updraughts inside the basin, so from the ridge above you watch them from over their backs rather than under them. The other way to the bottom is a steep, slippery path to the pool where the column lands and beats itself into drifting white mist. Down there you are soaked within minutes, shouting to be heard, and looking 192 metres straight up at the ledge you were standing on. The gorge is a near-perfect amphitheatre of dark basalt, so the roar comes back off the curved walls long after the water has landed. In the old telling here, that sound is not an echo at all: it is the wailing of the people who have drowned in the pool.
