Harrismith is an important crossroads in South Africa's land trade routes. This tranquil town was founded in 1849 by British Governor Harry Smith, who tried to persuade the Voortrekkers not to abandon KwaZulu-Natal. The first location for Harrismith proved to be deficient in water, so the town moved to its current location in 1850.
During the diamond rush in Kimberley, the town became a busy staging area on the Natal transport route, and hotels, grocery stores and public building started to spring up. In 1892 the railway from Natal to Harrismith opened, but due to political problems, it did not go any further for some time.
Harrismith was a major base during the Anglo-Boer War, it has progressed since then to become a charming and delightful town, housing several churches and public buildings. The annual Berg Marathon is held in Plattberg, which is one of the most prestigious cross country running events in South Africa.
