The Blyde River's spectacular canyon is one of South Africa's most impressive natural formations. It is located within the Blyde River Canyon Nature Reserve which follows the escarpment above the Blyde River as it carves its way down to the lowveld. Along the river, there are many wonderful viewpoints and endless hiking possibilities. Some of the most impressive sights are: the Pinnacle rock formation, the Wonder View and God's Window with amazing vistas of the canyon, the strange cylindrical holes carved in the rock by whirlpools and called the Bourke's Luck Potholes, the Three Rondavels, rock cylinders with hut-like pointed roofs rising out of the far wall of the canyon, and Echo Caves where Stone Age relics have been found.
