"The most picturesque, if not the highest, hills are... to be found in the county of Perth. The rivers find their way out of the mountainous region by the wildest leaps, and through the most romantic passes connecting the Highlands with the Lowlands. Above, the vegetation of a happier climate and soil is mingled with the magnificent characteristics of mountain scenery, and woods, groves, and thickets in profusion clothe the base of the hills, ascend up the ravines, and mingle with the precipices. It is in such favoured regions that the traveller finds what the poet Gray, or some one else, has termed beauty lying in the lap of terror."
Sir Walter Scott
