WHERE: Zhangye, China
WHEN: Year round, best time to visit is June to September

For millennia, the Rainbow Mountains have been the canvas for an organic artwork, thanks to changes in the mineral make-up of the layers of sandstone that are the peaks’ base material, leading to the unexpected palette of colours. The mountain range is part of the Zhangye Danxia Landform Geological Park, a UNESCO World Heritage Site in China’s north-western Gansu province.
