The city is well-connected by road to both the Ibadan and Lagos metropolitan areas. Notable geological features of the Oka-Akoko region are the steep-sided, dome-shaped inselbergs (giant outcroppings of rock) that dominate the landscape. In the past these rock outcroppings served as outposts to defend the city. Oka-Akoko lies in the Yoruba cultural region and supports a large Muslim population. Population (1995) 139,600.
