Amboseli National Park, formerly Maasai Amboseli Game Reserve, is in Kajiado County, Kenya. The park is 39,206 hectares (392 km2; 151 sq mi) in size at the core of an 8,000 km2 (3,100 sq mi) ecosystem that spreads across the Kenya-Tanzania border. The local people are mainly Maasai, but people from other parts of the country have settled there attracted by the successful tourist-driven economy and intensive agriculture along the system of swamps that makes this low-rainfall area (average 350 mm (14 in)) one of the best wildlife-viewing experiences in the world with 400 species of birds including water birds like pelicans, kingfishers, crakes, hamerkop and 47 raptor species.

The park protects two of the five main swamps, and includes a dried-up Pleistocene lake and semiarid vegetation. About 240 km (150 mi) southeast from the capital city Nairobi, Amboseli National Park is the second-most popular national park in Kenya after Maasai Mara National Reserve.

The park is famous for being the best place in the world to get close to free-ranging elephants. Other attractions of the park include opportunities to meet Maasai and visit a Maasai village. The park also has views of Mount Kilimanjaro, the highest free-standing mountain in the world. Amboseli was home to Echo, perhaps the most researched elephant in the world, and the subject of many books and documentaries, followed for almost four decades by American conservationist Dr Cynthia Moss. Echo died in 2009 when she was about 60 years old.

Amboseli National Park offers some of the best opportunities to see African wildlife because the vegetation is sparse due to the long, dry months. The protected area is home to African bush elephant, Cape buffalo, impala, lion, cheetah, spotted hyena, Masai giraffe, Grant's zebra, and blue wildebeest. A host of large and small birds occur too.

The park has several rules to protect the wildlife: Never leave the vehicle, except at designated spots; do not harass the animals in any way; always keep to the tracks; no off-road driving; and always give the animals the right of way. The roads in Amboseli have a loose surface of volcanic soil that is dusty in the dry season and impassable in the wet season.
