Make the great escape to Missouri’s wilderness – Taum Sauk Mountain State Park. The park provides 7,448 acres of solitude amid unspoiled land with a wilderness quality hard to find in today’s world. Taum Sauk Mountain State Park is located in the St. Francois Mountains, one of the most rugged and scenic areas of the state. Almost 1.5 billion years ago, volcanic eruptions of hot ash settled and cooled to form rhyolite. Erosion has left only the roots of these mountains behind, now dotted by oak-hickory forest and rocky glades.
