Hoyles Mouth is a natural limestone cavern near Penally / it was used as a place of shelter
by hunter-gatherers in the Old Stone Age / Flint tools and adinole (similar to Feldspar)
have been found here also bones of animals like the cave bear, now extinct, dating from
before 15,000 B.C. The cave system consists of a main chamber and two passageways,
one of which runs underground for about 40m , connecting a number of small
and remarkable caverns running through the limestone .
The cave is home to colonies of lesser horse shoe and pipistrelle bats and should not be entered.
