Blythe River Canyon
It's quite long drive from Marakele to Kruger so we opted for a 2-day stopover in Graskop to explore Blythe River Canyon and restock before hitting the next game park.
Highlights in that area include the gold digger town of Pilgrims Rest and various viewpoints along Blythe River Canyon. The area also has lots of hiking oppotunities but we found it too hot to move.
