Lake Bogoria is a located in the northern Kenyan Rift Valley. The lake is famous for the pink flamingoes which are found in large numbers.

Geothermal activity in the form of hot springs and geysers are located on the western shore. Lake Bogoria has the largest number of geysers in Africa.

The lake lies in a trough below the Ngendelel Escarpment, a sheer wall 600 metres (2,000 ft) high. The lake covers 32 square kilometres (12 sq mi). It is geothermically active on the western shore, with geysers and hot springs.

The reserve is in a semi-arid area. The only major river feeding the lake is the Waseges River, which rises on the northern slopes of the Aberdare Range. The Waseges runs through productive agricultural land higher up, through bush and scrub used for grazing, and then through very dry bush before entering the lake at its northern end. The lake is surrounded by grasslands dotted with bushes. There is acacia-ficus woodland to the south, and the north merges into a papyrus swamp.

The park was opened in November 1970. Facilities for tourists include the park lodge, three public campsites and one privately operated campsite. Visitors may also bathe in the hot springs, which form a natural spa
