Tharaka-Nithi drops from Mount Kenya's summit zone to hot lowlands near the Tana River. Its people are the Chuka, Muthambi, Mwimbi and Tharaka.
Why it matters
Its Mount Kenya forest feeds the Tana River, Kenya's main hydropower source. It also offers the Chogoria route, often called the most beautiful way up Mount Kenya.
The economy
Tea and coffee grow in the highlands, with sorghum, millet and green grams in the lowlands.
