The Collywobbles is a series of twists and turns in the Mbhashe River in the Amathole District Municipality of the Eastern Cape of South Africa.
The Mbhashe River rises in the mountains of the southern Drakensberg, and flows eastward across an undulating grassland coastal plateau until shortly after passing under national road N2, the river encounters southwest of Elliotdale and north-east of Dutywa the more rugged terrain of the Wild Coast and suddenly enters into a 64 km long series of violent twists and turns known as the Collywobbles before continuing more sedately to discharge into the Indian Ocean.
[1][2] In the area enclosed by the river's twists and turns, are the agricultural settlements of Msikiti, Zangcete, KuLombete and Mkhalalo.
At one point on the river where it twists close together there is a dam in the northern bend from which water is diverted via a 1.4 km long tunnel to the Colley Wobbles hydro-electric power station in the southern bend to bypass the 34 km that the river meanders between the dam and the power station.
The Collywobbles Vulture Colony has been designated as an Important Bird Area (IBA SA088) specifically to promote the conservation of this threatened species.
