Moreleta Kloof Nature Reserve, Nature reserve in Pretoria, South Africa.

Moreleta Kloof is a nature reserve in Pretoria covering about 100 hectares of grassland and woodland habitat. Zebras, springbucks, blesboks, impalas, duikers, bushbucks, and ostriches roam freely across these natural landscapes.

The reserve lies on part of the farm Garsfontein, bought by Jacobus Cornelius Rademeyer in 1859 and run as a dairy farm. Carel Erasmus purchased it in 1877 and built a house later converted into a chapel still in use. In 1903 Erasmus's son-in-law Johan Marnewick built another house, now the restaurant Rademeyer's.

The reserve's name comes from the Moreleta Spruit, and its farm buildings carry the family history: the house Carel Erasmus built after buying the farm in 1877 became a chapel still in use, while Johan Marnewick's 1903 house now serves as the Rademeyer's restaurant. A gazebo on the grounds is used for weddings.

The reserve has four marked trails: Rademeyer (1.6 km), Duiker (2.9 km), Suikerbos (3.3 km) and a sensory trail for the disabled. Summer gates are open 07:00–16:00 (closed at 17:00); winter 07:00–17:00. The Afrikaans source gives 06:00–18:00 year-round, so confirm times before setting out.

A tributary of the Moreleta Spruit runs through the grounds and provides year-round water for the animals living here. This permanent water source makes the area especially attractive to wildlife in the surrounding region.
