(S/E) Park at the Steel Rigg car park (grid ref. NY750676). Return to the lane and turn right. After a short way there is a signed footpath on the right and you need to follow this right of way as it crosses fields past Peatrigg and Long Side to reach a path junction just north of Hotbank Farm. Follow the farm track a short way northeast before waymarks lead you on across more fields towards a small plantation (easiest route is around it rather through it as waymarked!) to reach the Wall at King's Wicket (grid ref.NY798694).
(1) With the easiest section behind you, the switchback route now follows the Wall back to Steel Rigg car park for a distance of approximately four miles. This section is some of the best preserved and does benefit from including Vercovicium Fort (Housesteads) en-route. There are many better qualified people to inform you of the details of the Wall but suffice to say it is very impressive. The remains (mostly foundations) at Housesteads are remarkable with much to see and investigate. As you walk perhaps you should try to imagine what it was like to be stationed here in winter after enjoying the Mediterranean warmth of Italy!
(2) Leaving Housesteads the route switchbacks up and down as it follows the most advantageous contours of the natural escarpment. I particularly liked the section along the crest of Hotbank Crags and the final stretch above Crag Lough and along Peel Crags. Both these sections are very enjoyable and enable you to get a feel for the area besides enjoying the history(S/E).
In conclusion this walk is a must for anyone visiting Northumberland ... if only history was as interesting at school!
