Pen Y Fan footpaths funds needed, says National Trust
It is the iconic Welsh peak which attracts more than four million visitors a year.
But conservationists fear the sheer volume of hikers at Pen Y Fan, in the Brecon Beacons, could erode thousands of tonnes of soil.
The National Trust, which maintains the path network, said it spends £100,000 a year on central Beacons paths.
It has made an appeal for the public to help raise cash to ensure footpaths are maintained.
