1. Reed Flute Cave

Reed Flute Cave in Guilin, China was discovered during the Tang Dynasty almost 1,300 years ago.

Far below the Earth’s surface, where the sun rarely penetrates, is a world of twinkling glow worms, precious gems and limestone caves and mountains, a land inhabited by nature alone. Within this world are visions to rival many landscapes decorating our horizon; lakes lie still and calm, great networks of caves know no borders, and rivers and rivulets carve an ever-evolving terrain.

We invite you to explore this remarkable subterranean domain through these incredible images we’ve complied for your viewing pleasure.

3. Hamilton Pool

Hamilton Pool Preserve, in Austin, Texas, was created quite naturally when the dome of an underground cave collapsed revealing this stunning natural pool. It is now frequented by day-trippers and naturalists. That’s naturalists not naturists, although no doubt someone has tried to go skinny dipping at one point!
