Wikki Hot Springs, in Bauchi State, Nigeria, lies at the heart of Yankari National Park. Its thermal water emerges at 40°C in an open-air pool surrounded by savanna, suited to wild bathing.
Insider tip — Wikki Warm Springs in Yankari National Park is Nigeria's most celebrated natural thermal pool, maintained at a remarkably constant 31-38°C year-round by geological upwelling. The crystal-clear water flows over white sand in a jungle clearing visited by baboons, waterbuck, and elephants at the river's edge at dawn. The pool is clean enough to swim in with eyes open, making it exceptional in West Africa. Book a banda at Wikki Camp to have the springs to yourself before the day-trippers arrive.
