Mikumi National Park borders Selous Game Reserve on the south, the two areas forming a unique ecosystem. Two other natural areas bordering the national park are the Udzungwa Mountains and the Uluguru Mountains. Malundwe Mountain is within the park, the highest of a belt of hills that run east and west through the park, connecting the Uluguru Mountains to the northeast with the Uvidunda and Udzungwa mountains to the west. Malundwe Mountain consists of three peaks along a ridge running north and south. Malundwe’s south peak is the highest point in the park, reaching 1290 meters elevation.
The Mikumi landscape is often compared to that of the Serengeti. It borders with Selous Game reserve in the south forming a unique eco-system with two other parks areas of the Udzungwa Mountains and the Uluguru Mountains. The road that crosses the park divides it into two areas with partially distinct environments. The area northwest is characterized by the alluvial plain of the river basin Mkata. The vegetation of this area consists of a savannah dotted with acacia, baobab, tamarinds, and some rare palm. In this area, at the furthest from the road, there are spectacular rock formations of the mountains Rubeho and Uluguru. The southeast part of the park is less rich in wildlife, and not very accessible.
The fauna includes many species characteristic of the African savannah. According to local guides at Mikumi, the chances of seeing a lion who climbs a tree trunk is larger than in Manyara (famous for being one of the few places where the lions exhibit this behaviour). The Park contains a subspecies of giraffes that biologists consider the link between the Masai giraffe and the reticulated or Somali giraffe. Other animals in the park are elephants, zebras, impala, eland, kudu, black antelope, baboons, wildebeests and buffaloes. At about 5 km from the north of the park, there are two artificial pools inhabited by hippos. More than 400 different species of birds also inhabit the park.
The Mikumi belongs to the circuit of the wildlife parks of Tanzania, less visited by international tourists and better protected from the environmental point of view. Most of the routes that cross the Mikumi proceed in the direction of the Ruaha National Park and the Selous. The recommended season for visiting the park is the dry season between May and November, with warm weather and beautiful sites that are a once-in-a-lifetime experience.
