The park was founded as a private tourist attraction in 1895 by the Lexington and Eastern Railroad. In 1910, Louisville and Nashville Railroad acquired the land when it purchased the Lexington and Eastern Railroad. In 1926, L&N's President Wible L. Mapother turned over its approximately 137 acres to the Kentucky State Park Commission, making the Park one of Kentucky's original four state parks when that system was established the same year. There are over of trails over uneven terrain from moderate to strenuous difficulty, including trails to White's Branch Arch, Henson's Cave Arch, and other scenic areas. Some of the most famous sites are the arch itself, "Lovers Leap", and "Fat Man's Squeeze". The park's "Original Trail" to the natural bridge dates from the 1890s. Other trails include the Sand Gap Trail and the Balanced Rock Trail. Five miles of the Sheltowee Trace National Recreation Trail run through the park, including the Whittleton Trail which connects the park to the Red River Gorge Geologic Area. Activities such as hiking off-trails, disturbing wildlife, or collecting plants are not legal in any Kentucky State Park, and pets are not allowed on most trails at Natural Bridge State Park. "Fat Man's Squeeze", a narrow passage in the rock formation, leads to the bottom of the arch. Natural Bridge has several unique sandstone rock formations, including the Balanced Rock. This is a huge block of sandstone balanced on the edge of a cliff near the Natural Bridge. The "Balanced Rock", is located on Trail #2, not far above Hemlock Lodge. In the early days of the Park, it was called the Sphinx because, when viewed from the correct angle, it crudely resembles the Sphinx in Egypt. Although it is now called the Balanced Rock, it is in fact a pedestal rock - a single piece of stone that has weathered in such a fashion that its midsection is narrower than its cap or its base. This formation is one of the biggest and most perfectly formed examples of a pedestal rock east of the Rocky Mountains.
