The Lakes of Ounianga, a UNESCO World Heritage site in Chad, are a stunning cluster of 18 desert lakes sustained by ancient groundwater in the hyper-arid Sahara. Ranging from freshwater to hypersaline, their vivid colors and unique ecosystems defy the surrounding arid landscape, supporting diverse aquatic life and rare species. Recognized for their geological and natural significance, they stand as a remarkable testament to environmental resilience.
