The Hex River Valley – Geology, History & Innovation

1 August 2026

Bounded by the Hex River and Kwadouw (Quadu) Mountains, the Hex River Valley (HRV) is a mix of orchards, rivers, dams and settlements, the largest being De Doorn’s. It is especially attractive in Autum when the vineyards are transformed by a kaleidoscope of autumn hues. In winter snow often mantles the mountains and peaks flanking the Valley, dominated by the Matroosberg (2 230m), the highest peak at the north-east end of the Valley.

The Valley is planted with over 8 million vines, with some 5,000ha under irrigation and the largest producer of export table grapes in southern Africa. Striking autumn colours produced by the vine leaves during May and June, against a backdrop of snow-covered peaks makes the Hex River Valley a favourite destination for tourists and photographers during this season Geology of the Region The geology of the Valley is dominated by Cape Super Group rocks, primarily of the Table Mountain Group forming the high, rugged Hex River Mountains (including the Matroosberg at 2,230 meters) comprising hard, erosion-resistant quartzitic sandstones and sandy shales (Peninsula and Skurweberg Formations). Bokkeveld Group rocks replace sandstone in the northeast of the valley, with softer shales and characteristic Karoo-style butte landscapes.
