This section is 21 kilometres in length and has a maximum ascent of 600 metres.
The route is mainly off road the last 2 miles in Scotland after crossing out of the Northumberland National Park.
This section has no points on route where refreshments can be bought and is more open, so prepare well for the walk. Although well signed a good map and compass are essential to guide you over the Northumberland National Park and to assist in pointing out the many hills that will be seen on the way.

The ascent out of Wooler becomes pronounced near to Wooler Common and the Humbleton Burn.

The walk takes you through a local nature trail onto the Common and back into the forest before reaching the open hills.

The climb reaches close to its top at Gains Law. There then follows high level moorland walking towards Tom Tallon's Crag.
This section is the most exposed and sometimes the view of the rounded Cheviot hills may be lost in cloud.

On the right Yeavering Bell (1182ft) is Northumberland's largest ancient hillfort site.
The surrounding area of Yeavering traces its history back to around St Cuthbert's time when Paulinus was said to have brought Christianity to the community.

From Yeavering there is a descent past a small holding at Torleehouse where you turn to the left and head SW towards Hethpool

It is worth leaving the route before the woods to look at Hethpool Linn where there are attractive waterfalls. The main route follows field and forest to Hethpool.

Crossing the College Burn you reach Hethpool, the only community you will pass on this section of the walk. The community has some 1920's cottages designed by Robert Mauchlin. This is also the location of the "Collingwood Oaks", a group of trees on Hethpool Bell which were planted by Admiral Lord Collingwood, Nelson's second in command.

From Hethpool to Elsdonburn Farm the walk is along a metal road running beside the Elsdon Burn.
You are sure to have company from the local livestock grazing next to the roadway.
The ascent continues from the farm steeding towards Eccles Cairn and the border between England and Scotland.

The route is now on hill paths and descending. It is not far before the St Cuthbert's Way joins the Pennine and E2 walking routes.

It now follows round the south face of Green Hambleton before reaching the Halfwayhouse at the Halterburn.

The final 1 to 2km is on a narrow country road. You can soon look ahead over the Bowmont Water and valley to see the twin towns of Kirk and Town Yetholm.

With Kirk Yetholm Green in sight you pass the Gypsy Palace, a small cottage that has been home to the Faa family over the 19th century.
There are a few hotels and B&B in Town and Kirk Yetholm. The latter also has a Youth Hostel to rest at but not many shops to visit.
