Great Rift Valley, also known as the East African Great Rift Valley, is the largest fault zone on Earth, with more than 6000 kilometers, which is known as "The Largest and Most Beautiful Scar on the Face of Earth." Someone who hasn't seen the valley would think it to be dark and long. However, it offers you one of the most beautiful sceneries in the world. A large amount of old-growth forest covers the mountains. At the bottom of the valley, more than 20 lakes scattered everywhere resemble a network of sapphires embedded in this magic area. Lake Turkana in the north is one of the birthplaces of mankind.
