Coast to coast along the old Roman frontier, 84 miles from Wallsend to the Solway, milecastle by milecastle
Indicative — sampled from open terrain data along the simplified route.
Hadrian’s Wall Path runs 135 kilometres, or 84 miles, from Segedunum Roman Fort at Wallsend on the Tyne to The Banks at Bowness-on-Solway, tracing more or less the whole line the Romans built to mark the northern edge of their empire. Walk it in either direction and the wall, or what’s left of it, is rarely far from the path for long.
Here’s a fact worth carrying around: for a good stretch through the central section, the wall runs along the top of the Whin Sill, a slab of hard volcanic rock that was squeezed in between older layers of rock roughly 295 million years ago while still molten, then left standing proud as a ridge once the softer rock around it wore away. The Romans didn’t put that ridge there, obviously, but they knew a good defensive line when they saw one, and building along the top of it meant the wall did double duty with the landscape rather than against it.
The route crosses Northumberland and the Solway Coast on its way between the two seas, taking in wooded river valleys like Allen Banks and Staward Gorge as well as the open moorland further west. Roman remains turn up along the whole length, from forts and milecastles down to smaller traces easy to miss at a fast pace, so it’s worth taking things slowly.
Most people walk it west to east or east to west over the best part of a week, and the central section in particular has real ups and downs along the crags, enough to catch out anyone expecting a flat stroll. It’s exposed, high ground for a good part of its length, so proper boots and a weather eye matter, and the Northumberland stretch in particular can be a long way from anywhere to shelter if the wind picks up.
