Explore a Cave
Five great caves you can explore.
Crystal Cave - Mexico
Giant Crystal Cave, in Naica, Chihuahua, Mexico, contains some of the largest crystals ever discovered. The crystals - the largest one being 39' long and weighing 55 tons - were formed over 500,000 years when a magma chamber under the cave heated and filled the ground water with minerals. Researchers believe there might be other caverns with giant crystals, but to get to them, they would have to demolish the crystals that have already been discovered.
Stephen's Gap - Alabama
This vertical cave in Alabama can be entered either by repelling the 143' drop through a keyhole, or scrambling down some rocks through a second entrance. Either way you might get splashed by the waterfall that enters the cavern near the ceiling.
Blue Grotto - Capri
The entrance to the Blue Cave is so close to sea level that visitors usually drive up in a motor boat, then change to a small row boat and lie flat on their backs as they pass under the rock entry way and into the cave. Inside, a second underwater entrance - which is 10 times bigger than the surface level entrance - provides light that makes the cavern appear bright blue.
Majlis al Jinn - Oman
This is the ninth largest cave chamber in the world; locals know it as Khoshilat Maqandeli. It was discovered by Americans W. Don Davison, Jr. and his wife, Cheryl S. Jones in 1983. Cheryl's Drop is one entrance where you can repel 158.2' into the chamber.
Crystal Cave - Bermuda
According to local legend, Crystal Cave was discovered by two boys searching for a cricket ball in the grass. Another boy, the property owner's son, was lowered into the cave to check it out. Today the 500 meter long underground cave is Bermuda's most famous, and contains waterways as well as caverns with stalactites and stalagmites.
