You are first able to start this sidequest as soon as you beat Gattuso and reach that cliff area for the first time. However, it becomes unavailable if you enter Ragou's mansion in Capua Nor before starting it. If you went to Ragou's place before activating the first part of the sidequest, you're out of luck.
