Things To Do

Go spelunking underneath the Smoky Mountains.  Tennessee is home to the most caves in the United States, with over 8,350 caves registered to date.

There are two main caving adventures into the heart of the Smokies.  Both are natural wonders, offering guided tours, and both are convenient to our Pigeon Forge cabin rentals and Gatlinburg cabin rentals.

Forbidden Caverns:  Located in Sevierville, TN is one of America's most spectacular caverns.  Visitors are provided with an entertaining and educational tour past sparkling formations, towering natural chimneys, numerous grottos and a crystal clear stream.  Special lighting effects, a stereophonic sound presentation and well-trained tour guides combine to make this a most enjoyable experience.  The trails are well-lighted, with handrails at all necessary points.  Open daily April through November, 10 a.m. - 6 p.m. Closed on Sundays.  Closed Thanksgiving Day, December, January, February and March.

Tuckaleechee Caverns:  Located in Townsend, TN, Carved over tens of thousands of years in one of the earth's oldest mountain chains,Tuckaleechee Caverns at Townsend, Tenn., are known as the "Greatest site under the Smokies".  Estimated to be between 20 and 30 million years old, the Caverns are rich in history and lore in recent years as well.

 

How Formations Develop:

Cave formations are commonly known as "cave onyx." It is brittle and will break like glass.  The acid from the touch of one's hand to cave onyx will destroy the gloss on it and make it dull and unattractive.

Cave onyx is formed by surface water which combines with carbon dioxide which is given off by plants, and forms a mild carbonic acid.  The acid dissolves limestone rock (calcium carbonate) and forms calcium bicarbonate which is soluable in water.  This solution seeps down into the cave.

The limestone will stay in bicarbonate form only as long as the carbon dioxide is present.  Since carbon dioxide is normally a gas, it takes pressure and low temperature to keep it in the solution.

This pressure is furnished by the ground as the solution seeps through and the coolness is furnished by the natural coolness of the earth.

When this bicarbonate solution reaches the cave ceiling, the pressure is relieved and the solution warms up.  This releases the carbon dioxide and the calcium bicarbonate turns back to plain old calcium carbonate which is not soluable in water so it is deposited on the cave ceiling or floor in the form of cave onyx.

The rate of drip is an important factor in the rate of growth and shape of the formation.  If the drip is slow, most of the deposit is left on the ceiling. If it is fast, the major deposit is left on the floor.  A slow drip makes faster growth than fast drip.

The average growth of formations is about one cubic inch per 100 years!
