The Big Bull Bully In The Nairobi National Park A few weeks ago, we drove down towards the murram heaps near No 10 junction. I chose to use the rougher track to approach the area, in the hope of seeing something unusual of interest. About 1 km from the murram heaps we saw a big massive white rhino bull. He was very impressive and calm at the same time, as he slowly moved forward while grazing grass at intervals.
