The most spectacular stretch is the Blyde River Canyon which can be reached from Graskop via R532. Just a few kilometres north a small loop road leads to "God's Window", from where you will enjoy a wonderful view on the Lowveld. The Canyon starts at "Bourke's Luck Potholes" and ends at the "Three Rondavels". From many well-positioned vantage points one has a view of the 33 km long gorge. The Potholes are very impressive rock formations that were shaped millions of years ago by erosion. The bizarre swirl holes developed when the once rapid river carried masses of sand and debris.
