Hutton Roof Crags limestone pavement

Ninety-nine hectares of the finest limestone pavement in Britain on the fell between Kirkby Lonsdale and Burton-in-Kendal, with clints and grikes running out of hazel scrub and dark-red helleborines in the crevices. Cumbria Wildlife Trust publishes the reserve as dogs on a lead and records cattle grazing at times. The red waymarked circuit from Clawthorpe Road is a mile and a half; the Trust warns that paths are narrow, uneven and muddy and cross pavement that is slippery when wet, so a dog dragging on a lead is a good way to turn an ankle. Take the OS map, because the scrub makes navigation harder than the distance suggests.
