This section is 14.8 miles (23.7km) long - a map of it can be downloaded below.
This section provides contrasting landscapes, some lovely settlements with plenty of facilities, and finishes on the outskirts of the major town of Reading.
The first few miles of your walk pass through wide open countryside with large undulating arable fields stretching away to the east to a beech wood skyline.
Soon the hills begin to dominate with the Berkshire Downs rising to the west and the wooded Chilterns to the east. This, the Goring Gap, is the narrowest part of the Thames Valley with the river, a railway and a road all squeezed together between the hills on either side.
From just south of Wallingford, The Ridgeway, another National Trail and thought to be the oldest road in Britain, follows the opposite bank of the River Thames as far as Goring-on-Thames. Here it strikes west into the Downs on its way to Avebury, having crossed the Thames Path on the bridge over the River Thames.
