Ruma National Park is the only park in Nyanza Province. Also known as the Lambwe Valley Game Reserve, it was constructed to protect its vast population of rare roan antelopes that cannot be found anywhere else.
The park is located in Western Kenya close to Lake Victoria, in Lambwe Valley in South Nyanza. The park covers an area of 120 kilometres. It has two gates, and the roads are three main circuits accessible by vehicles all year long.
