If you’re heading north from Kumasi towards Tamale take a detour near Techiman to visit the Monkey Sanctuary between Boating and Fiema. There are 2 types of monkey in the Sanctuary - Black and White Colobus and Campbell’s Mona. The Mona live high in the trees eating leaves, while the Colobus eat a wide variety of food.
The monkeys are protected and treated as sacred. There is also a graveyard where monkeys and priestess are buried together.
