MAPS showing new access land in the North have gone on sale.
The revised Ordnance Survey maps follow the opening up of parts of the countryside previously off limits to ramblers.
Map makers have used Countryside Agency data to produce updated OS Explorer maps.
The aim is to ensure clarity for walkers, landowners and farmers by showing the extent of the areas where people are allowed to walk on land away from public footpaths for the first time.
The maps use a light yellow tint surrounded by a narrow, pale orange border to indicate the access land.
Vanessa Lawrence, director general and chief executive of OS, said: "We are delighted to support the new access opportunities by revising our Explorer maps for the North.
"These maps have been chosen for the task because their detail makes them ideal for outdoor activities.
"On the revised versions we bring together both new and existing access areas in a clear way."
A first batch of 18 revised maps covers the Lake District and all Cumbria, the Yorkshire Dales, North York Moors and much of Northumberland.
A further 17 titles will follow in the summer.
OS is revising its Explorer series in stages as access land is made available under the Countryside and Rights of Way Act 2000.
The OS says that people venturing off well-defined paths should be alert to the importance of map-reading skills.
It also warns that there are legal limitations to the new rights of access and gives a website contact for map users to check an area before setting out: www.countrysideaccess. gov.uk
The Countryside Agency's Tayo Adebowale said: "We want to encourage everyone to get out, explore and enjoy the countryside. The areas now being opened up are rich in wildlife and scenery.
"But it is important to follow the countryside code."
OS marketing manager Gail Meadow said: "The new maps show miles upon miles of new access land from the Lake District to Hadrian's Wall.
"Walking is a great way to get fit and burn off calories and the maps will help people make the most of the new opportunities
