The wow factor: Guilin in China is famous for its stunning karst mountain scenery, which was used as a backdrop in the HSBC TV advertisement featuring a cormorant fisherman. But below ground is equally stunning, with a number of show caves open to the public, all brightly illuminated by neon lights. Among them are Reed Flute Cave in Guilin and Silver Cave in Yangshuo.

Did you know? The karst mountain scenery on the Li River between Guilin and Yangshuo is depicted on the back of China’s 20 yuan note.

Stay: A three-night extension from Guilin to Yangshuo and back with Wendy Wu Tours, including a Li River trip, overnight in Yangshuo and visit to Guilin’s Reed Flut Cave, costs from £390.
