Description - 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. 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.
Recreation - Recreational opportunities include; fishing, picnicking, walking trails and a scenic viewing area. There are guided tours available, call ahead for details.
Climate - Massachusetts experiences four distinct seasons with slightly varying temperatures in the inland and coastal regions. Along the coast the water is a moderating factor that often prevents large amounts of snowfall from accumulating through the winter. Summer temperatures are usually cooler than low lying inland areas, due to ocean breezes. This region of the country experiences high humidity in the summer season and temperatures that average close to 80 degrees F. Fall and Spring are pleasant times to visit the region with crisp air and low humidity. Brilliant foliage colors can be found in the central and western regions of the state in late September and October. Winter temperatures can be brutally cold on occasion with a humidity-filled wind, but on average winter daytime temperatures reach 35 degrees F and lows reach into the teens. Spring is usually the wettest time of year, but trees, bushes and flowers are blooming by early May.
Natural Bridge State Park is located in the northern Berkshires in western Massachusetts. From East or West/Rte. 2: Take MA Rte. 2 to North Adams and intersection with MA Rte. 8 north. Turn onto Rte. 8 north and continue for 0.5 miles to McCauley Road and park entrance on the left. Follow the dirt road; it soon becomes paved.
