$20 for Admission for One Adult to 2.5-Hour Treetop Obstacle Course ($45 Value)

Participants spend 2.5 hours navigating the obstacle courses at their own pace and as many times as they please. Treetop Quest recommends arriving 30 minutes before the reserved course time.

Treetop Quest

Nestled in the high branches of Gwinnett Environmental & Heritage Center, a network of ropes, ladders, and bridges invites amateur adventurers to scurry across their lengths. Although Treetop Quest’s obstacle courses hover as high as 55 feet above the ground, guests stay safe thanks to a belay system that’s impossible to detach at canopy level. During self-guided adventures, they encounter more than 70 obstacles, whooshing along ziplines, scaling rope nets, and carefully crossing suspension and monkey bridges. Before guests ascend through the branches, instructors issue them harnesses and gloves and give them a thorough safety briefing. The courses vary in difficulty and height to accommodate all experience levels and ages, allowing visitors as young as 4 to enjoy a challenge, even if it’s just trying to sweet-talk a squirrel into sharing his stash of Corn Nuts.

Amid the excitement, Treetop Quest educates patrons on the surrounding environment through plaques and info boards at each course level. The courses operate sustainably to respect their arboreal hosts; the structures are treatment-free and don’t puncture the trees in any way.
