WALKERS are being challenged to reach the peak of silliness by climbing Pen-y-Ghent, Whernside or Ingleborough wearing an off-the-wall hat.

The Yorkshire Dales National Park Authority (YDNPA) launched the project to raise funds for path maintenance around the Three Peaks.

To take part donate £5 to the project, take a ‘selfie’ at the top in your hat, share it on the authority’s Twitter or Facebook pages and challenge three friends to do the same.
