Hi George, Thanks for reaching out! Our Treetop Journey course requires there be at least one adult to supervise every 8 youth (ages 6-15) in the trees. This adult can participate, but can also supervise from the ground. Our Treetop Journey course uses a continuous belay system which means that all participants are attached from the bottom of the staircase that leads you into the trees, all the way through the bottom of the zipline when you're returned to the ground! Hope we'll see you and your granddaughter soon! KF
That would be suggested.
Depends on the course.
