In the Valley of the Giants is the spectacular Tree Top Walk. A 600m-long ramp rises from the valley, allowing visitors access high into the canopy of the giant tingle trees. At its highest point, the ramp is 40m above the ground. It's on a gentle incline so it's easy to walk and is accessible by assisted wheelchair. At ground level, the Ancient Empire boardwalk (admission free) meanders through veteran red tingles, up to 16m in circumference and 46m high.
