Bartholomew’s Cobble is named for its two rocky knolls—or “cobbles”—rising above the Housatonic River. Hurlburt’s Hill, the property’s highest point, rises 1,000 feet to a 20-acre upland field on the Massachusetts-Connecticut border that offers panoramic views northward up the Housatonic River Valley. Boasting an enormous variety of woodland flowers and fern species, the Cobble’s amazingly diverse flora earned it a National Natural Landmark designation in 1971.

Ideas for Your Visit

Explore five miles of trails and discover the diversity of this landscape—open fields, transitional forests, freshwater marshes, a pair of small caves, and more. Along the way, you’ll find one of North America’s greatest diversities of fern species as well as one of the largest Cottonwood trees in the state. Paddle the Housatonic River, tour the on-site natural history museum, and make sure you return between mid-April and the end of May, when the wildflowers reach peak bloom across the property’s 329 acres.

Join local naturalist and artist, Nanci Worthington on her long term citizen science project at Bartholomew’s Cobble. The last Saturday of each month (weather dependent) she will lead a 2 hour guided course on nature journaling where she will focus on different sections of the property each month and document the changes in landscape, flora and fauna throughout the year for hopefully years to come!

The reservation is named for George Bartholomew, a farmer who purchased the fields and uplands in the late 19th Century. But more than a hundred years earlier, Col. John Ashley had gathered together a sprawling estate of which the current reservation was only a part. The Trustees acquired the Cobble in 1946. Ashley’s home, also owned by The Trustees, still stands on nearby Cooper Hill Rd.

I love to hike the 6.5 miles of trails, walking up the Hill, down to the Housatonic River, via The Spero trail, circling back on Bailey and then to Ledges. Get on one of their full moon canoe trips, the best of the best!
