Once there, follow the small path by the river till you hit a wider path up the hill to the castle. Note that the path loops up the hill to the left before curving right to the castle. Walk round the castle to the right slightly and a small but obvious path goes off to the right. Follow this to 'Lover's Leap' (marked with a green post and arrow) to the right, which is a viewing point with iron railings on three sides, just below this is the crag which is well hidden from the path.
