Underground Pool Reflection, Reed Flute Caves, Guangxi province, China
Just outside Guilin there is a hidden gem called the Reed Flute caves. It's just beautiful in there. I had to go through as part of a tour party as there was no other option so I spent all my time racing ahead with my tripod. This shot is of a pool, that when undisturbed becomes a natural mirror.
