Climbing up from Halterburn around Green Humbleton (287m) – the first of many hillforts along St. Cuthbert’s Way – you will soon reach the national border between Scotland and England. A short diversion to Eccles Cairn will reward you with your last views of the Borders and the Eildon Hills. At the border you will cross into Northumberland National Park, one of Britain’s best kept secrets.
St. Cuthbert’s Way drops back down via Elsdonburn to Hethpool, at the head of the College valley and home of the Collingwood Oaks. Then onwards through woodland and a good track along the Cheviot foothills, heading for Yeavering Bell (361m), Northumberland’s largest Iron Age fort. A lovely path leads through the heather over Gains Law down to the small market town of Wooler, where you will find shops, accommodation, food and drink and everything you might want.
