Even before you cross the new cycle/pedestrian bridge over teh Doon you'll have spotted Greenan Castle precariously balancing on it's cliff edge. Shortly you'll be passing it on your way to Durure where another castle echoes the stance. This is an ideal picnic spot. Pause, too, at the compact little harbour.
