Editor's note: These stunning caves aren’t part of some fairy-tale world or horror movie – they can be found in some of the world’s most remote places in Asia, North America and Europe. Caves like these usually form when water seeps down through cracks in limestone rock. Over millions of years, these openings, and the limestone left behind by dripping water, can form the majestic caves you see here.
