Meet at the William H. Morrissey Visitor Center at Mystery Cave

Caves, disappearing streams and sinkholes make up a landscape called karst. Cherry Grove Blind Valley Scientific and Natural Area is a hidden gem in the story of karst topography. Master Naturalist volunteer, Ann will reveal these unique geologic features up close on this 1 mile hike. Come prepared to cross over a shallow stream on stepping stones by wearing sturdy shoes. Bug spray is recommended too. Meet at the William Morrissey Visitor Center at Mystery Cave for a brief introduction and follow Ann in your own car about 6 miles to the Cherry Grove SNA.
