Discover a geologic wonder at this 48 acre park. Examine the only naturally formed white marble arch and man-made white marble dam in North America, and tour an abandoned marble quarry. The “natural bridge” for which the park is named, according to geologists, is 550 million year old bedrock marble, carved into an arch by the force of glacial melt water over 13,000 years ago; one of the best places in New England to demonstrate the effects of glaciation. The bridge spans rushing Hudson Brook as it twists and tumbles through a steep 60-foot deep gorge.
Noted Romantic writer, Nathaniel Hawthorne, visited here in 1838 and recorded his experience about Hudson’s Cave (or Falls) in An American Notebook “The cave makes a fresh impression on me every time I visit it … so deep, so irregular, so gloomy, so stern.” The site was an active commercial quarry from 1810 to 1947, producing coarse-grained white marble used in local buildings and cemeteries. From 1950 to 1983 it was a privately-owned and popular roadside tourist attraction off the Mohawk Trail. Natural Bridge became a state park in 1985, to preserve its unique geologic features.
In the summer months, knowledgeable park interpreters are on hand to explain the natural forces that created the bridge and its more recent human-related history. There is a 0.25 mile walkway above and through the chasm, and a 0.5 mile wooded walking trail.
