At 54.600 Km the Selous is the largest game reserve in Africa . To put it in perspective, the Selous is larger than Switzerland and half the size of the U.S. state of Ohio. Until recently, the reserve was only accessible by plane or by train. However, with an improvement to the road network, the area is now accessible to everyone. The concentrations of wildlife in the Selous are understandably huge. The Selous, named after a German explorer and author, boast Tanzania's largest population of elephant currently about 10,000 animals as well as some of Africa largest numbers of buffalo, hippos, Nile crocodile and wild dogs.

Other species commonly seen are lion, bushbuck, impala, giraffe, eland, baboon, zebra and greater kudu. The Selous also contains one of the few viable populations of black rhinos in the world, with between 150 and 200 individual animals. The reserve also contains more than 350 different bird species and 2,000 different species of plants.

The Selous was designated a UNESCO World Heritage site in 1983 due to its unique ecological importance. The landscape is shaped by the Rufiji River and its tributaries, lined by Barrassus Palms, and it is the heart of the park. The Rufiji swells through the park down to the Indian Ocean forming a series of small lakes that serve as an important source of water for the multitude of the plains game. It is only in the Selous Game Reserve that one can combine game drives, boat tours and walking safaris. The hinterland around Lake Tagalala and Beho Beho is some of the most picturesque in area
