Namibia's best-known tourist attraction Etosha National Park was proclaimed as Namibia's first conservation area in 1907, and is one of the largest game reserves in Africa. Of the 114 mammal species found in the Park, several are rare and endangered. Etosha is a combination of dried lake (salt pan) in the north and grasslands, dense brush and open plains in the south. Almost all African animal species are represented in the nature reserve. Well maintained gravel roads lead to watering holes, where game viewing is best. Etosha is home to more than 3,000 species of birds and large animals,among them the elephant, giraffe, zebra, leopard, cheetah, lion, kudu, black-faced impala, black rhino and hyena. The park is open all year, but the best time to visit is August-September. The Etosha Park is about 400 km north of Windhoek.
