Over-enthusiastic visitors as well as erosion are causing problems on Hadrian's Wall. There is a short piece at the Ordnance Survey about changes to the walking trail for those who wish to walk the length of the wall:
Walkers wishing to complete the Hadrian's Wall walking trail will have to use a slightly different route to normal if they are to prove their success.
A new stamping point – where walkers have a passport stamped to prove they have visited each of the required markers along the path – has been introduced at Housesteads Fort.
This is to divert people away from Knag Burn, where a steep slope is at risk of eroding.
The point at Housesteads Fort is the seventh on the famous walking trail, popular with hikers as it offers a combination of the great outdoors and historic relevance.
New signs – that could be used in conjunction with maps – have also been erected to keep people on the right track.
