Natural Bridge Caverns

Natural Bridge Caverns are the largest known commercial caverns in the state of Texas.The name was derived from the 20 m (65 foot) natural limestone slab bridge that spans the amphitheater setting of the cavern's entrance. The span was left suspended when a sinkhole collapsed below it.

The caverns are located near the city of New Braunfels, Texas in the Texas Hill Country next to the Natural Bridge Wildlife Ranch, a drive-through wildlife safari park. The caverns feature several unique speleothems and other geological formations. The temperature inside the cave is 21 degrees Celsius (70°F) year-round and the deepest part of the public tour is 64.3 m (211 feet) below the surface.

The caverns are still very active and growing. Water flows and drips constantly throughout, causing the formations to retain a waxy luster that can be seen in few caverns.

Famous quotes containing the words natural, bridge and/or caverns:

    It is a dogma of the Roman Church that the existence of God can be proved by natural reason. Now this dogma would make it impossible for me to be a Roman Catholic. If I thought of God as another being like myself, outside myself, only infinitely more powerful, then I would regard it as my duty to defy him.
    Ludwig Wittgenstein (1889–1951)

    In bridge clubs and in councils of state, the passions are the same.
    Mason Cooley (b. 1927)

    ... the bold care of an ecstatic trull
    Who rearranges with impartial feet
    The silence in the caverns of a skull.
    Allen Tate (1899–1979)
