At the beginning of the 20th century, elephants had become a problem to the farmers in the eastern Karoo and a professional hunter, Major Jan Pretorius was assigned to shoot them. By 1920 he had shot 114 and only 11 remained. Conservationists woke up and in 1931 the Addo Elephant National Park was set up in the dense valley bushveld of the Sundays River region. The Addo elephants, currently numbering 430, are almost all descended from the original herd. The Park has the big 5 and the animals here are very relaxed.
