Moss on the water. Something soothing for today's image. In stark contrast to the imposing ruins of Hermitage Castle, the little river of Hermitage Water tumbles by the castle with immense charm. The river, and castle, sit among the gentle hills of the Scottish Borders, close to the border with England. The river is a pristine example of the crystal waters that seep from the moors into the glens to tumble over the exposed rocky beds. Water splashed onto the larger rocks feeds an amazingly lush and vibrant growth of Scottish moss.
