Since May 2005, large areas of Northumberland National Park are accessible to the public as a result of the Countryside and Rights of Way Act 2000 (CROW). This means that you can now walk feely on designated 'Access Land' without having to stay on rights of way.
Up to date information about access land, where you can go and what you can do is available on the Countryside Access website.
Open Access Land across the National Park is clearly mapped on all the new Ordnance Survey Explorer Series maps, which were revised in time for the commencement of this new right.
Look out for the new waymarking symbols that show when you are entering or leaving Access Land.
