Lake Kivu is located in the East African Rift Valley, near the equator. It's Africa's sixth largest lake, and is shared between Rwanda and the Democratic Republic of the Congo. 

You can visit Nyamirundi Island, which is a popular destination for coffee lovers. You can learn how coffee is grown, taste local coffee, and buy some to take home. 

Lake Kivu contains large amounts of methane gas, which is trapped in the water at depths of 200 meters below the surface. The gas is created by volcanic activity and indigenous bacteria. 

The Rwandan government is working on using the methane gas to generate electricity. The KivuWatt project is one such initiative that has been operating since 2015. The Shema Power Lake Kivu Ltd project is another initiative that will use the gas to generate electricity.
