Limestone Way
The Limestone Way runs for about 50 miles from Castleton to Bonsall near Matlock, and then down to Rocester in Staffordshire. There's also a leg from Bonsall into Matlock. The distinctive scenery of the route is limestone - dales, outcrops and castle kopjes.
There are two path signs for the Limestone Way - an older one showing a ram, and the newer text-only one shown above.
