Haltwhistle likes to call itself the centre of Britain, and whether or not you believe the measurements, it sits at the very heart of Hadrian's Wall country. Just outside the town, on a gentle slope called Sunny Rigg, the outlines of two Roman temporary camps have been traced, rectangular enclosures with rounded corners where units on the march, or building the wall, pitched their leather tents behind a bank and a ditch for a night or a season. They are part of the Frontiers of the Roman Empire World Heritage Site, though on the ground you will see only faint lines in the grass, best appreciated from the air or in low evening light.
North of Haltwhistle, the wall reaches its most dramatic stretch, riding the crags of the Whin Sill, a hard volcanic rock that forms steep cliffs facing north. Cawfields, Walltown Crags, Steel Rigg and Housesteads are all close, and the Roman Army Museum at Carvoran gives an excellent introduction. The famous Sycamore Gap tree, a landmark beside the wall, was illegally felled in 2023, an act that shocked the whole country; the gap remains, now without its tree.
The riding around here is a mix of busy and quiet. The A69 through the Tyne valley is fast and carries a lot of traffic, while the B6318 Military Road, a few miles north, rolls across open moorland on the line of the wall, with blind summits that demand care. Minor roads north into the Northumberland National Park and toward Kielder Forest are narrow and empty, with cattle grids, sheep and wide views.
Haltwhistle is a small market town with fuel, shops, pubs and cafés, and Hexham, about twenty-four kilometres east, is larger. The weather is changeable, with wind and rain common, so carry waterproofs. Late spring and early autumn offer the best combination of light, weather and quiet trails.
