About a mile from the town is the entrance to the famous stalactite cavern of Adelsberg, the largest and most magnificent in Europe.
Granite and serpentine rocks predominate, but the shores of Amboyna Bay are of chalk, and contain stalactite caves.
Each stalactite, stalagmite and pilaster was measured, numbered, and removed in sections.
The Mitchelstown limestone caves, exhibiting beautiful stalactite formations, are 6 m.
Various volcanic rocks are the predominant formations, but beds of limestone also occur, giving rise to numerous stalactite grottoes all over the island.
On the shore of the lake is the stalactite cave of Jobitsinal, of great local celebrity; and in its depths, according to the popular legend, may still be discerned the stone image of a horse that belonged to Cortes.

The only remarkable feature in the island is a stalactite cavern on the south coast, which is reached by a narrow passage broken by two steep and dangerous descents which are accomplished by the aid of rope-ladders.
Of these the chief are Poole's Hole, a vast stalactite cave, about half a mile distant; Diamond Hill, which owes its name to the quartz crystals which are not uncommon in its rocks; and Chee Tor, a remarkable cliff, on the banks of the Wye, 300 ft.
In these caverns there are numerous stalactite structures, which, from their curious and fantastic shapes, have received such names as the Image of the Virgin, the Mosaic Altar, &c. The principal parts are the Paradies with the finest stalactites, the Astronomical Tower and the Beinhaus.

High (not all can be seen from any part, and probably some portions are still unexplored), shows many remarkable examples of stalactite formations and incrustations of dazzling brilliance.
Their presence is due to lateral outgrowths of crystals shooting from the side of a growing stalactite, or to deflections caused by currents of air, or to the existence of a diminutive fungus peculiar to the locality and designated from its habitat Mucor stalactitis.
In the neighbourhood is a fine stalactite grotto, which often served as a place of refuge to the inhabitants in war time.
