The valley of the Vaal River is the setting for the town of Lindley, founded in 1875 and named after an American missionary, Daniel Lindley.
A weir has been built across the river and this holds back a 5km stretch of deep water ideal for fishing, boating and swimming.
After the Anglo-Boer War a local resident, John Collister-Oats led a campaign during which many thousands of trees were planted in the valley.
Lindley is a centre for dairy products and the site of a powdered milk factory.
It has become a popular inland holiday resort.
