Cave-Spring along the Current River. Not too long ago the only access to this beautiful location was from the river. Recently some nice folks built a really great trail (~5 miles round trip) that starts at Devil's Well (another great Ozark exemplar of karst topography).
JACOB'S CAVE ~~A thoroughly delightful smaller cave, Jacob's Cave today is one of the best show caves for access and lighting and the only Missouri cave that is TOTALLY accessible by wheelchair. Jacob's Cave is located between Versailles and Gravois Mills off Missouri Highway 5, on State Road TT. It is jam-packed with many very nice and various types of speleothems, and also boasts one of the best examples of potholes in the Midwest. An active, "living" cave, Jacob's is a true delight.
