The Groot River rises in the Komsberg Escarpment of the Great Karoo, about 40 km south of Sutherland in the Northern Cape Province, and is known as the Komsberg in its upper course. Flowing southeastwards it becomes the Buffels River. It then bends southwards through Laingsburg and flows first southeast, then south into the Floriskraal Dam, and then southwest, before it flows southwards again and cuts across the Klein Swartberg Mountains through the Buffelspoort, a deep gorge, into the Little Karoo.
The river eventually becomes the Groot River at the point where the Buffels and the Klein-Swartberg River meet, about 50 km before its confluence with the Touws River, and then it flows eastwards, past Van Wyksdorp, towards its confluence with the Gourits River.
Its main tributary is the Touws River that rises in the Hex River Mountains, and flows eastwards through the town of the same name and south into the Little Karoo, where it joins the Groot River's right bank.
