Crater Lake is a green, high-alkaline lake at the bottom of an extinct volcano. This 10,000 acre game sanctuary is great fun to explore on foot independently or with a local guide. The area is alive with hundreds of species of birds and many mammals, large and small. While walking through the conservancy, you can spot gazelle, giraffe, zebra, eland, baboon, and black-and-white colobus monkeys - just to name a few.
You can also take the short walk to the rim of the beautiful volcanic crater and admire the views down to the emerald-green lake in the crater. Depending on the water levels of other Rift Valley lakes, there are sometimes large populations of flamingos on the lake.
