The Umtamvuna Nature Reserve is situated in South Africa on the KwaZulu-Natal side of the Mtamvuna River, and is managed by Ezemvelo KZN Wildlife.

[1] The reserve includes a section of the Mtamvuna River, and surrounding cliffs and plateaus, from the outskirts of the town of Port Edward to 19 km inland.

[2] The plateau areas consist of grasslands (Pondoland Sourveld), which drop off into Coastal Scarp Forest in the gorge along the river below.

[1] The cliffs were formed by the river incising into Natal Group Sandstone, and many endemic plants grow on this substrate and the soils derived from it.

[3] The grassland areas of the reserve are known for their natural display of wildflowers in late spring, depending on rainfall and burns.
