The Aerial Treetop Adventure is closed for the season - reopening weekends beginning May 25. 

Constructed in the trees near Gunstock's fishing pond, the Aerial Treetop Adventure (ATA) course is New England's largest treetop obstacle course! Explore Gunstock from a bird's-eye view.

81 challenges are securely suspended within the trees for a combined total of eight high-ropes courses, including two demos and the Explorer Course made just for kids. Features include: log ladders, bridges, swings, seesaws, foot bridges and of course, lots of ziplines.

The adult Areial Treetop Adventure begins with a training course where our Adventure Park guides show you how to use the equipment to ensure that you understand and can demonstrate that you can safely navigate the ATA. After you feel comfortable and the guide has signed off on your skills, you move to the first adventure, the Green Course. which is closest to the ground (10-15 feet) and challenges are the easiest.

Each course increases in difficulty and height. The final, Black Course rises up to 100 feet from the ground and icludes a 165-foot-long foot bridge with irregularly spaced planks. For more details about the specific courses click HERE.
