The zoo was originally founded as the Middlesex Fells Zoo in 1905 before being renamed in honor of curator Walter D. Stone.
It is home to a successful breeding program for the critically endangered Mexican gray wolf.
The zoo features a 'Himalayan Highlands' exhibit specifically designed to mimic the rugged, mountainous environments native to snow leopards and markhors.
Its location is situated directly adjacent to the Middlesex Fells Reservation, a large state-managed forested area.
The facility maintains a 'Treasures of the Sierra Madre' exhibit that showcases species from the Mexican mountain ranges.
Stone Zoo is a 26-acre facility located in Winchester, Massachusetts, managed by the non-profit organization Zoo New England. The park is characterized by its hilly, wooded landscape that provides a naturalistic setting for its diverse collection of animals. Notable exhibits include the 'Windows to the Wild' building and the 'Treetops and Riverbanks' area, which features primates and North American river otters. The zoo focuses on animal conservation, education, and research initiatives. Visitors can observe species such as snow leopards, jaguars, black bears, and a variety of tropical birds. The layout emphasizes pedestrian paths that weave through the forested terrain of Spot Pond Brook. The facility serves as an accredited member of the Association of Zoos and Aquariums.
The elevated boardwalk at the 'Treetops and Riverbanks' exhibit offers high-angle views of the animal habitats.
Wear comfortable, supportive footwear as the zoo is built on hilly, uneven terrain.
Check the zoo's online calendar for daily keeper talks and scheduled animal encounters before arrival.
Visit the 'Windows to the Wild' building during colder months to view tropical species in a climate-controlled environment.
Do not expect a large-scale, flat-path city zoo; the hilly terrain requires more physical exertion than typical urban parks.
Closed on Thanksgiving and Christmas Day.
Do not feed or attempt to touch the animals; maintain a quiet demeanor near enclosures to avoid disturbing wildlife.
