We had a very tasty light lunch at the the Red Lion pub in Culworth after about 4 miles walking. I have modified the walk slightly since completion.
Directions
Take the M40 South. At J11 (Banbury) take the first left onto the A361 towards Daventry. After about 3 miles take a right turn signposted Edgcote. After 0.75 miles park on the left on the grass verge after a group of houses.
