COLOBUS MONKEYS IN DIANI! Early one morning, I walked out behind our accommodation at Diani Beach Chalets to explore the natural sights. Suddenly a movement caught my eye, it was a colobus monkey in a tree above me. Then I saw more movement in the tree canopy above me, as an entire troop of more than ten colobus monkeys slowly emerged. As I watched them, they were quite relaxed as they fed on green leaves.
