This section is 27 kilometres in length and has a maximum ascent of 400 metres. It is one of the more arduous and will require in excess of 6 hours walking. You go over the highest and midway point (50km) of the complete route at the summit of Wideopen Hill.

The twin villages of Yetholm are on either side of the Bowmont Water. It is said that the churchyard was the burial ground of a number of Nobles killed at Flodden.

This is also the home of the Scottish Gypsies, traced back to James V with a writ in 1540 referring to Johnne Faa. The last Gypsie Queen, Ester Faa Blytte, died in 1883 ending the "royal" line.

The first stages of the walk take you past the Romany Marsh a small wild life reserve. You would hope to see a variety of wading birds and ducks at this location.
Having passed Primsidemill the main ascent of the walk lies ahead over Crookedshaws Hill and onto the ridge that leads to Wideopen Hill.

From here the views in all directions are breathtaking, so do not be tempted to take the short route to Morebattle by the valley.
The walk remains on the high ridge to Grubbit Law then descends into the Kale Water Valley close to Morebattle.

The landscape in this area of the Kale Valley has changed significantly over the years. Up until the middle ages there was a Loch or Lake close by that run from Morebattle to Eckford.

With time the Teviot eat a channel into the loch near Eckford draining it into the Teviot. This causing the Kale to realign and cease to be a tributory of the Bowmont Water.

The village of Morebattle has a hotel, several B&B's and a few shops where refreshments can be purchased.
The walk is now on road until shortly after Cessford Castle when it returns to farm track and fields over Cessford Moor.

The castle built around 1450, is now a ruin but was the home of the Kers, the direct ancestors of the Duke of Roxburghe.
The castle seems to be in a very exposed location. However if you recall the earlier comments on the Loch near Morebattle this explains how the original location was next to water and marshland.

The route now follows farm tracks and the edge of fields as the Way rises onto Cessford Moor.

At the end of the new route the Way reach the highest point on Dere Street. The Way is now north towards the Teviot River in the valley below.
The Teviot has by this point run the majority of its length before entering the Tweed at Kelso. It and its tributory the Kale have been relevant to today's walk with the latter having a great significance to the Morebattle and Cessford locations.

Another connection relating to the Teviot is that of the hills recently crossed. It is thought that the closeness in name and location of the river to the Cheviots is no accident.

The route although marked as part of Dere Street is far from straight once it meets the Jedwater. The crossing of it and the Teviot demand a significant zig zag route over a reconstructed footbridge.

The third days walk is nearly over with a final few minutes walking round the edge of the Monteviot House Estate. The walk meets a "T" junction at a small footbridge over a burn, left takes you to Harestanes and refreshments, the straight ahead route is the continuation of Dere Street on the final leg of the St Cuthbert's Way.
