Day 1: Melrose → Kirk Yetholm
51.8 km / 32 mi · ↑975m · ↓956m · 9hRun the entire opening half in one push. Leave Melrose's market square past the 12th-century abbey, climb through Newstead and follow the River Tweed west with Eildon Hills views. Pass the Rhymer's Stone into St Boswells, cross Mertoun Bridge and join the Roman Dere Street with views toward the Cheviots, passing Harestanes Visitor Centre. Drop to the suspension footbridge over the River Teviot, rejoin Dere Street over a horse stile and traverse Oxnam Water and Cessford Moor — past a prehistoric settlement and the 15th-century Cessford Castle — into Morebattle. Climb steeply onto Grubbit Law (326 m) and Wideopen Hill (368 m), the highest point on the trail and roughly halfway. Descend through gorse and farmland to Kirk Yetholm, with the Border Hotel for the night.
Day 2: Kirk Yetholm → Holy Island
50.4 km / 31 mi · ↑980m · ↓1080m · 9hLeave Kirk Yetholm on farm tracks shared briefly with the Pennine Way, then climb the Cheviot edge across the unmarked Scotland–England border into Northumberland National Park. After heather moorland and views down College Valley (wild Cheviot goats), drop to Hethpool. Climb to Black Law (317 m), continue along the elevated path, then over Kenterdale Hill for the long descent to Wooler. Cross Weetwood Moor and the 16th-century Weetwood Bridge, run quiet lanes through East Horton to St Cuthbert's Cave in the Kyloe Hills, where Holy Island first appears across the sands with Bamburgh Castle beyond. Drop through Shiellow Wood to Fenwick, cross the A1, and follow field paths to the causeway. CRITICAL: check Holy Island crossing times — impassable 2 hours before to 3 hours after high tide. Finish at Lindisfarne Priory.
