Devil's Mill
"At the Devil's Mill, the river, after running in a rocky channel with a rapid descent enters a deep basin formed in the rock; from this basin it descends into a cavity below, where the water is whirled about with great violence, and, constantly beating against the sides of the rock, produces a sound like that made by the machinery of a mill in motion.
The Devil's Mill is best reached by public footpath. On the West side of the Rumbling Bridge there is a metal gate set into the wall. There is a steep step down on the footpath. This path is secured with fencing, and also has viewing platforms built by the Army which give beautiful views of the gorge. Devil's Mill is about a 10-15 minute walk upstream from Rumbling Bridge.After the Devil's Mill is a bridge which allows you to walk in a circular route back through the woods, with their magnificent beech trees, to the bridge. This walk is not long and can be managed by most people but it is slippery when wet, and not wheelchair friendly.
The level of the water changes dramatically according to the rainfall. Some days there is hardly a trickle coming into the pool, and the waterfall seems to be powered by underground currents. When the river is in full spate, the pool becomes a seething whirlpool and the river can rise enough to go round both sides of the central rock.
The Rumbling Bridge
"About 350 yards below the Devil's Mill is the Rumbling Bridge. On each side the rocks rise to the height of 86 feet, and approach so near each other that a bridge of 22 feet span connects them. The scene below as seen from the old bridge is frightful, and cannot be contemplated by the steadiest head without awe. A handsome new bridge has been lately erected above the old one, at an elevation of 120 feet from the bed of the river. Looking down the Devon from the bridge the prospect is truly sublime.
The best view of the finely wooded cliffs connected by the Rumbling Bridge is from a gentle eminence immediately below and opposite to it, upon the north bank. The river, both above and below, bounding from rock to rock each forming a little cataract, creates a constant rumbling noise; hence the name of the Rumbling Bridge. From the clefts in the face of the rock grow bushes and trees, among which daws and hawks nestle, and from these they are incessantly sporting, thereby giving a pleasing animation to the scene."
According to the Annals of Kinross-shire, the first Rumbling Bridge was built by William Gray, a Saline stonemason, in 1713. It is a stone bridge with a 22 feet span and 11 feet width. It is perched 86 feet above the average water level and has no rails nor parapets. In the 1700s the road would have sloped sharply down on either side making it treacherous in wet and icy conditions. Although during Victorian times there was a walkway built to access the bridge, this is no longer there and the bridge is not accessible today.
In 1816, a second wider upper arch which raised the level of the road and is edged by stone walls on either side. The bridge is now 120 feet above the water level.
The view down from the bridge is dramatic. To the north, you see the River Devon rushing down the gorge, making the rumbling sound that gives the bridge its name. To the south the view opens up and the river cascades even further down in a series of small falls.
This cache is on the north side of the river and takes you to the heart of the gorge.
Gps a bit eratic due to position of cache but clue should help.
