Whistling Cave is located at Spring Mill State Park. Parking for the cave can be found at the Pioneer Village. Pick up a park map at the entrance of the park to help you through your tour.
Whistling Cave believed to be the sixth largest cave in Indiana with over 8 miles of surveyed passageways. At the coordinates provided you will find the a entrance to the cave that has a locked gate for safety reasons. There are many other entrances to the cave that are located on private properties.
Most caves, including Whistling Cave, were created by a slowly moving water over a period of thousands of years.
Rain water picks up enough carbon dioxide from the air and soil to form a weak carbonic acid. This slightly acidic water seeps into the natural cracks in the limestone bedrock until it reaches the water table. The weak acid widens the cracks by dissolving the limestone and carrying it off. Eventually, the crack becomes large enough to be called a cave.
Cave exploration is not allowed in the park except for the right dry side of Donaldson Cave or by special permit.
