Packed with footpaths, bridleways and country lanes, and crossed by Britain's oldest ridgeway, Oxfordshire and West Berkshire offer some of the most varied and interesting walking in southeast England. 

Famed for the city of Oxford's dreaming spires and the Dukes of Marlboroughs' magnificent Blenheim Palace, the region is also home to the infant River Thames (or Isis), the eastern Cotswold hills and the Vale of the White Horse in the Berkshire Downs, which form part of the North Wessex Downs National Landscape.
