Please note: On Wednesday April 24 at Franklin Park Zoo and Thursday, April 25 at Stone Zoo, volunteers, zoo employees and local emergency responders will take part in routine animal escape exercises. While the exercise is occurring, guests have the opportunity to participate in the evacuation portion, and may be asked to move to certain areas within the Zoo for a brief period of time (not to exceed 10 minutes). These exercises are an important part of our preparedness training, and we appreciate your participation and understanding. If you have any questions about what to expect, please don't hesitate to contact us at 617-989-2000 or

Gorilla Grove

Gorilla Grove

Gorilla Grove is now closed for the season.
Be sure to visit the gorilla troop in their indoor Tropical Forest habitat. 

Zoo Map


Gorilla Grove features over 360,000 cubic feet for the troop to explore, including vines and trees for climbing, a cascading waterfall, and a multitude of built-in foraging opportunities for gorillas to discover throughout the day. 

Venture through the observation outpost to the heart of the habitat, where you’ll get a 360-degree view of Gorilla Grove. Come face-to-face with gorillas at the viewing stations around you, or look up, and you may see gorillas peeking in at you through the skylights as they climb overhead! 

Please note:
It must be at least 45 degrees and sunny for the gorillas to have access to Gorilla Grove. If it’s raining, the temperature cut-off is 55 degrees. We take cues from the gorillas and monitor weather conditions closely.
