Located around the south-western side of Lake Naivasha is the Crater Lake Game Sanctuary. This small game sanctuary is great fun to explore on foot independently or with a local guide. This 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, waterbuck, impala, 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 with 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 and other bird-life on the lake.
There is no public transport to Crater Lake so it is best accessed either by either bike or with a private vehicle or taxi. The road can differ in condition at different times of the year (depending on when it was graded last) and can be very dusty.
