The National Trust for Scotland, the Upper Deeside Access Trust (now the Cairngorms Outdoor Access Trust) and Highlands and Islands Enterprise have been very successful in generating funding for, and carrying out upland path improvements works, over the last 10 - 15 years. The path work on the Mar Lodge Estate, the Upper Deeside mountain path network and the Cairngorm Estate has involved programmes of capital works of varying magnitude, including £1.3 million of path work carried out by the National Trust for Scotland.
