Governed from its large modern capital city of Bahir Dar, on the southern tip of Lake Tana, Amhara covers an area of 170,752 square km and supports a population estimated at 19.2 million in 2013. Although the substantial cities of Bahr Dar, Gondar and Dessie all lie within Amhara, roughly 90% of the region's population is rural. The Amhara people for whom the state is named comprise more than 90% of the population, and Orthodox Christians outnumber Muslims by a ratio of 4:1. Several of Ethiopia most popular tourist sites lie in Amhara, most notably the former imperial capitals of Lalibela and Gondar. The Simien Mountains to the north of Gondar include Ethiopia highest peak, the 4,620m Mount Ras Dejen, and harbour the country's main concentrations of the endemic gelada baboon and Walia Ibex. Lake Tana, Ethiopia largest body of water and source of the Blue Nile also falls within Amhara, as does the Blue Nile Falls.
