Kenya boasts an outstanding variety of wild animals and Big Five viewing opportunities and safaris are the country's greatest attractions. Kenya's most visited park is the wildly beautiful Masai Mara National Reserve, a game viewers paradise with a high concentration of wildlife, including the Big Five, which is an extension of the Serengeti Plains in neighbouring Tanzania. Amboseli National Park is renowned for its herds of elephants and the backdrop of Africa's highest mountain, Mt Kilimanjaro. The Great Rift Valley is scattered with alkaline lakes that attract flocks of flamingos, as well as a variety of game: Lake Nakuru National Park has huge concentrations of game and is an important white rhino sanctuary; and Lake Naivasha is also a popular destination for bird watchers and those wanting to do water safaris. Walking safaris, horse riding safaris and hot air balloon safaris are all popular variations in Kenya.
The peak season for game viewing in Kenya is in the dry months between January and March, and July and October, because the animals congregate more around water holes at this time and it is easier to spot them when the vegetation is less lush and dense. The incredible natural phenomenon of the wildebeest migration draws many people to Kenya between June and August.
