With only 137 km2, the park contains three main areas that create an outstanding landscape. These are the Meru crater, which funnels the Jekukumia river, the Ngurdoto crater, and the colourful alkaline Momella lakes, which are home to many bird species. Arusha is home to Mount Meru. This active volcano is the second-largest mountain in Tanzania, with a height of over 4,566 meters above sea level.
