This month marks the 80th anniversary of the Great Trespass on Kinder Scout, but those who like to go walking
may be well aware there are some places that are still out of bounds.
An interactive map has been published by the Ramblers detailing some of the places where it is impossible to go - including Vixen Tor on Dartmoor, over which a public enquiry was held and concluded last year that owner Mary Alford was within her rights to fence it off.
The map covers locations all over England and Wales and even includes one spot in the Peak District, Ossoms Hill in the Staffordshire Moorlands. It was excluded from right-to-roam status under the Countryside and Rights of Way Act 2000 because it had too much tree cover, although the Ramblers hopes the new edition of the map will be updated with this status.
Others include the Cefn Meriadog Estate in north Wales, which covers 20 sq km, but has less than 3.5 km of footpaths because the parish council that drew up the definitive map of paths in the 1950s was dominated by the landowner and his tenants.
And not far from Vixen Tor in Devon, another landowner is causing trouble by refusing to allow workers access to the banks of the River Coly to install the three bridges needed to make effective the right-of-way status the path by the waterway has.
But absent bridges are not just down to awkward landlords, with Camarthen County Council being identified as the culprit in failing to rebuild a bridge at Dreflin that could help restore a popular route.
However, while the Ramblers has noted some problems around the country, there are many reasons to cheer as the 80th anniversary (April 24th) approaches. Soon after, on May 5th, Wales will become the first nation on Earth whose entire coastline is accessible via a coastal path.
So while much may need to be done, plenty of progress in opening up the countryside has been achieved.
