Summary The reserve centre lies 11 km due south of Impendle town, and about 50 km west of Pietermaritzburg. The terrain is undulating, steep and rocky at the highest points, and dissected with small river drainage lines that fall over a minor escarpment as they join the Umkomaas River. The site is predominantly grassland. The vlei is very good for African Marsh Harrier Circus ranivorus, Grey Crowned Crane Balearica regulorum and occasionnaly Wattled Crane Bugeranus carunculatus.
