Aerial Treetop Adventures

Built in the trees near pond, the Aerial Treetop Adventure (ATA) course is New England's largest aerial obstacle course. Explore Gunstock from a bird's eye view. The ATA is part of the Discover Adventure Package, it cannot be purchased as an a la carte product.

91 different challenges are securely suspended within the trees in 8 high ropes courses, including the Explorer Course just for kids. Some of the features include log ladders, bridges, swings, seesaws, foot bridges and, of course, lots of zip lines.

The Adult Adventure begins with a training course where our Adventure Park guides will 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: Green course. Green is closest to the ground (10-15 feet) and the games are the easiest.

Each course gets more challenging and the elevations get higher. If you make it all the way through, you'll finish on the Black course where you will be upwards of 100 feet off the ground, crossing a 165 foot long, irregularly spaced foot bridge.
