Hidden Valley Nature Center is 3.4 acres of wetlands and wooded hillside nestled between the town’s Meeting House Hill School and the High School. Approximately one mile of self guided trails wind around and through the valley of oak, maple and hickory trees. These, along with many varieties of bushes and low lying flora, provide habitat for deer, skunk, opossum, raccoon and gray squirrels. As many as 160 species of birds have been sighted in the valley and pond. A man made pond is home to turtles, a few species of fish, frogs and toads along with other aquatic animals. A self guided tour brochure may be obtained at the center. There is a small museum, pavilion, lecture circle along with rest areas along the trails. An observation deck juts out into the pond.
New Fairfield Parks and Recreation and the New Fairfield Land Trust jointly oversee the programs at Hidden Valley. Each year programs such as maple sugaring, herb walks, ecological discussions, bird watching, tree identification walks, etc. are offered at the Center. The New Fairfield Boy Scouts with the help of the New Fairfield Lions Club donate countless hours of labor to maintain this preserve for generations to come.
