The Lake District and Yorkshire Dales national parks have been extended by 188 square miles, with campaigners hailing a “historic day”.
The park borders have grown within touching distance either side of the M6 motorway, creating a band of protected land across the north west of England.
Originally designated in the 1950 s, the expansion of the borders aims to boost rural tourism.
The Yorkshire Dales has grown in size by 24%, with the Lakes increasing 3 %.
The move, announced by the Department for Environment, Food and Rural Affairs in October , watches the Dales stretch to the north and west and the Lakes to the east and south.
Most of the Yorkshire Dales park is in North Yorkshire, but 28% of its land is now in Cumbria and 1% in Lancashire.
Despite the change in geography the Yorkshire Dales National Park Authority said the government had no plans to change the park’s name, which was written on a designation order in 1954.
