Towards late afternoon, the great, unyielding canopy slowly softens its fierceness, and from pastel shades of pink and blue, the colours deepen, setting the endless Karoo canvas ablaze with glorious hues of orange and red. The Great Karoo is a vast and unforgiving landscape of which the Karoo National Park is but a small portion. Being the largest ecosystem in South Africa, the Karoo is home to a fascinating diversity of life, all having adapted to survive in these harsh conditions. Karoo National Park is dominated by the lofty Nuweveld Mountains and rolling plains, where many species that originally occurred here now occupy their former ranges.
