Natural Bridge State Park is home to the only naturally formed white marble arch/bridge in North America. This 48-acre park also has two other very unique features: the only man-made white marble dam in North America and an abandoned marble quarry. The ancient marble bridge is said to have been formed by a glacier melt thousands of years ago most likely. Fishing, picnicking and walking along the unique marble forms are popular activities here. The park also offers informative interpretive programs about the historic site.
There are two walking trails on the property-- one is .25 mile and the other is .5. One takes you through the chasm and another is a wooded trail.
