Rab's 8½ mile walk went through the Altar Stones Nature Reserve before climbing up to Billa Barra Hill. The name of the hill is thought to be a corruption of the word "barrow," meaning burial ground. The hill top is a Regionally Important Geological Site, with a natural outcrop of pre-Cambrian rocks, similar to those found at Bardon Hill and Cliffe Hill nearby.
The route took us between two of the many quarries in this part of Leicestershire to Stanton under Bardon before returning through Thornton and Markfield.
