Botswana lies immediately to the north of South Africa. It is bordered on the north and west by Namibia, on the north and east by Zimbabwe, and is connected by a narrow strip of land on the northern border to Zambia. Its territory consists almost entirely of a broad, flat, arid subtropical plateau(高原), though there are hills in the eastern part of the country.
In the northwest, the Okavango River empties into the Kalahari sands, creating the largest inland river delta in the world. While the Okavango Delta is home to relatively few large animals in comparison to other areas of Botswana, its clear waters and countless small islands are home to a variety of birds, plants, and smaller species of animals.
Nearby is Chobe National Park, a beautiful grassland reserve(保护区) that has gained international fame for its large elephant population. Southeast of Chobe are Botswana's large Makgadikgadi salt pans, home to numbers of blue wildebeest, several antelope species, and those international lovers of salt pans, flamingos(a kind of birds).
Almost the entire remaining portion of the country is covered by the Kalahari Desert--a varied environment of sand and grassland. Although this area of Botswana is where few people live, it is one of the richest wildlife areas in all of Africa.
Botswana's two largest parks, the Central Kalahari Game reserve and Gemsbok National Park, are found in this region.
Botswana's climate can get rather cool, particularly during the dry winter months of June to August when night occasionally brings frost. The rainy summer months (December through March) are best avoided for those interested in enjoying the best game viewing conditions.
