Nestled in the hills above the Loutre River in Montgomery County, Graham Cave State Park features an unusual sandstone cave that contained evidence that rewrote history books. Once used for shelter, Graham Cave became historically significant when archaeologists discovered how long ago human occupancy had occurred.

University of Missouri archaeologists uncovered artifacts revealing human use of the cave dating back to as early as 10,000 years ago. Clues to the lifestyle of the ancient Dalton and Archaic period Native Americans were uncovered. Today, visitors are allowed in the entrance of the cave, where interpretive signs point out interesting discoveries.

Surrounding Graham Cave is 356 acres of naturally diverse land designated as Graham Cave State Park. Several trails wind throughout the park's forests and glades. A boat ramp on the Loutre River provides access for boating and fishing. An open picnic shelter, playground areas and picnic sites make the park an ideal place for a day of family fun. For those in need of a longer retreat, a wooded camping area offers basic and electric campsites, modern restrooms and hot showers.
