Rwanda has many lakes. The largest, Lake Kivu, is located in the midst of the volcanic peaks in the Virunga Mountains and forms part of the border with the Democratic Republic of the Congo. The lake has a surface area of 2,665 square kilometers (1,025 square miles) and reaches a maximum depth of 475 meters (1,558 feet).
Rwanda has a temperate tropical highland climate, with lower temperatures than are typical for equatorial countries because of its high elevation. Kigali, in the centre of the country, has a typical daily temperature range between 12 and 27 °C (54 and 81 °F), with little variation through the year.
The culture of Rwanda is varied. Unlike many countries in Africa, Rwanda has been a unified state since precolonial times, populated by the Banyarwanda people who share a single language and cultural heritage.
