While in Arusha National Park we drove up Mount Meru, one of the highest mountains in Africa. This is the only place we found Blue Monkeys (which aren't Blue) and Black and White Colobus Monkeys (which are black and white). Both the Blues and the Black and Whites were only seen high in the trees. This was on our second day of the Safari (6/26 - 7/7/16). The photo has been chopped but no other pp has been done.
