Climbing aid structure includes a grappling hook. A throw line and a climbing line are attached to the grappling hook. The throw line is thrown over an overhead support (such as a tree limb), and the grappling hook is emplaced by manipulation of the throw and climbing lines. The climbing line is then oriented in an upright position and tensioned by use of a ground anchor. Hand-and-foot engaging, line-gripping elevator devices are positioned on the climbing line for ascent of the line by a climber. The line-gripping devices include levers which wedge against the rope under the weight of a climber, to grip the rope and provide support for the climber to ascend the climbing line.
