To appreciate the earth's natural beauty, sometimes you have to dig under the surface. Jaunted tips you off to the best caves in the world.
- Waitomo Glow Worms Caves, New Zealand: Abseil down a tiny hole, black-water raft for 3 hours, and then see a glow-worm-studded cave ceiling.
- Jeita Grotto, Lebanon: A natural cathedral, half of it accessible only by boat. Visitors say they can feel God's presence.
- Dos Ojos, Mexico: Snorkel in crystal-clear water with bats and prehistoric fish.
- Blue Grotto, Italy: Sunlight shines up from an underwater cavity, turning the water brilliant blue.
