From Haydon Bridge the road twists its way through woodland for a mile or so past Langley Castle then opens out passing the Carts Bog Inn (good food/beer). The road then descends through 3 hairpins to cross the River Allen at Cupola Bridge. More woodland through Whitfield (Elks Head Inn)before it then opens out again to climb steadily through mainly fast open bends to cross over Whitfield Moor. Descend through Alston which is a quaint small town with an amazing number of pubs for its size. Cumberland Hotel particularly recommended.From Alston the road climbs steadily to Hartside Top where a well known cafe is located. This a mecca for motor cyclists and the views to the Lake District are spectacular. Descend through a twisty but enjoyable section to Melmerby(Shepherd's Inn and Village Bakery). On through more open roads through Langwathby to Penrith. It is every bit as good in the opposite direction . A classic.
