It is the Free State's only national park, and is more famous for the beauty of its landscape than for its wildlife. Numerous paleontology finds have been made in the park including dinosaur eggs and skeletons.

Geography and climate

"Golden Gate" refers to the sandstone cliffs that are found on either side of the valley at the Golden Gate dam. In 1875, a farmer called J.N.R. van Reenen and his wife stopped here as they travelled to their new farm in Vuurland. He named the location "Golden Gate" when he saw the last rays of the setting sun fall on the cliffs.

In 1963, 47.92 square kilometres (11,840 acres) were proclaimed as a national park
