Loch Rannoch (Scottish Gaelic: Loch Raineach) is a freshwater loch in Perth and Kinross, Scotland. It is over long in a west–east direction with an average width of about , and is deepest at its eastern end, reaching a depth of . The River Tummel begins at its eastern end, where the small village of Kinloch Rannoch can be found, whilst the wild expanse of Rannoch Moor extends to the west of the loch. The area surrounding Loch Rannoch, along with Rannoch Moor itself, was formerly part of the native Caledonian Forest that stretched across much of Northern Scotland. Native forest is now largely absent from much of the area, due partly to logging, and partly to the climate becoming wetter, and Loch Rannoch is now largely surrounded by commercial forestry and open hillsides, although a small area remains at the Black Wood of Rannoch on the southern shore of the loch. Loch Rannoch forms part of the Loch Rannoch and Glen Lyon National Scenic Area, one of 40 such areas in Scotland, which are defined so as to identify areas of exceptional scenery and to ensure its protection from inappropriate development by restricting certain forms of development. Tourism The area around has many attractions, which can be found on the Rannoch and Tummel Tourist Association site which has information about the glen. The loch offers good sport fishing, with brown and ferox trout, arctic charr, pike and perch all present, although there are no salmon in the loch. Fishing is managed by the Loch Rannoch Conservation Association, who issue permits and control catches in accordance with the Salmon and Freshwater Fisheries (Consolidation) (Scotland) Act 2003. Areas of forestry around Loch Rannoch owned by Forestry and Land Scotland (FLS) form part of the Tay Forest Park, a network of FLS forests spread across the Highland parts of Perthshire that are managed to provide walks and amenities for visitors. Historical sites A crannog is present at Eilean nam Faoileag in the western half of the loch. A folly was constructed on the island in the nineteenth century, reputedly by a Baron Granbley. The folly, which is still standing, takes the form of a tower, and may be based on the design of a small island prison. There may also be crannog at Eilean Beal na Gaoire at the very western end of the loch, however the level of the loch has
