Dartmoor attracts millions of visitors every year
A scenic drive through one of Britain's most dramatic landscapes may soon cost more than just the price of a picnic and a flask of tea.
Plans are being considered to introduce car parking charges on Dartmoor National Park in Devon.
The park's authority believes introducing a fee could lead to a reduction in car use and lower the carbon footprint of visitors.
Money raised could also be ploughed back into sustainable transport.
Other national parks, including the Lake District, Peak District and Exmoor already charge for parking.
The report being discussed at a park's authority meeting on Friday recommends visitors are charged £1-a-day to park at Meldon, Haytor and Postbridge.
There is currently a voluntary charge at these sites.
It also suggests Princetown, in the middle of the moor, should adopt formal parking charges.
This could quadruple its revenue from parking. At the moment motorists simply place a donation in a hollow stone cairn.
Dartmoor covers 368 square miles (954km squared) of Devon.
It was designated a national park in 1951 and attracts millions of visitors each year.
