Riemvasmaak Natural Hot Spring lies in South Africa's Northern Cape, at the bottom of a gorge reached after a hike. The iron-rich water, pH 6.3, forms an open-air pool suited to wild bathing.
Insider tip — Riemvasmaak Natural Hot Spring is a thermal spring in the heart of the Riemvasmaak community nature reserve (Northern Cape), in the Gordonia district, on the banks of the Orange River. The hot water rises in a spectacular desert setting in the Augrabies mountains. Riemvasmaak was a community displaced under apartheid and returned to its inhabitants in 1994.
