Hundreds of people have gathered on Dartmoor to campaign for the right to wild camp.

In 2023, High Court judges ruled wild camping was allowed on some privately owned commons on the moor, but Dartmoor landowner Alexander Darwall is appealing against the decision.

Mr Darwall is taking the case to the Supreme Court on Tuesday where a final decision will be made.

Campaigner Lewis Winks said the right to wild camp was “a deeply educational gateway experience” to know the land.

Mr Winks, who is part of the Stars Are For Everyone campaign, said one of the phases of the court battle where landowners could give yearly permission for wild camping was “a very flimsy alternative to a right”.

He said: “If we were to replace rights with a permissive scheme, in 50 years time when my daughter is taking her children to Dartmoor then who knows what will be left of the right to wild camp.

“The rights lock in something which is historic and something we’ve enjoyed here for generations.”

About 450 people endured wet weather to attend the event at Hound Tor, organisers said.

Campaigner Emma Goodwin added: “I hope it sends a really strong message about how important this is that even on a day like this, this many people have turned out to say ‘not on my watch’.”

Dartmoor National Park Authority said it had sought to defend the public’s right to access the National Park.

“We have been consistently clear about our role in protecting Dartmoor and promoting understanding, so people respect the National Park’s environment, its cultural heritage and those who live and work here,” it said.

“While we await the final hearing and verdict from the Supreme Court, we remain committed to working with landowners and other partners to ensure that people enjoy Dartmoor responsibly.”

The BBC was unable to contact the Darwall family.

Previously, the Darwall’s and other landowners expressed concerns about the potential harm of camping when not done responsibly.

In January, Landmark Chambers, representing Mr Darwall, said the appeal “will determine once and for all this important issue.”
