Honeycomb Natural Bridge & Ghost Creek Falls

The Natural Bridge and Ghost Creek Falls are located in Marshall County near Grant, in the community of Honeycomb. Set amid the hills of the Cumberland Plateau physiographic section, the 25-foot-long natural bridge is the remnant of a collapsed cave. Ghost Creek Falls runs a few yards away alongside the bridge. The creek is so named because it meanders in and out of the rocky cliff, appearing and disappearing as it runs down the hill. There are also two smaller waterfalls near the home the owners built on the property that emerge from other underground areas along the cliff. In 2007, the site was named one of the Seven Wonders of Marshall County by area residents.

The natural bridge is located on private property, but the owners permit visitors, given the site's uniqueness. The property, which encompasses 40 acres, is located in a clearing at the bottom of a limestone cliff riddled with small underground waterways and springs; the type of geologic structure is known as karst. Over millions of years, the mildly acidic water has produced fissures, sinkholes, underground streams, and caverns in the region. The natural bridge is the remnant of such a cavern. Over time, the walls and roof of the opening were gradually worn away, and portions collapsed, leaving the natural arch as all that remains of the cavern's roof. The bottom layer of the natural arch continues to be very fragile, and sections of rock still occasionally fall out of the layers supporting the natural bridge. An attempt several years ago to open a quarry on adjoining property was thwarted by residents concerned about its effects on the natural bridge.

The property averages 25 visitors every week, with slightly more during spring flower season. There is a campground, beach, and public boat launch nearby for visitors to the area.
