Motorhome owners held a sit-in protest against barriers designed to stop people using car parks on the Lincolnshire coast as free campsites.
The final barrier, installed at Huttoft Car Terrace, was locked by council officers and police on Monday.
The barriers mean that high-sided vehicles cannot access Lincolnshire's five coastal car parks.
But Lincolnshire County Council said the barriers are necessary to stop people abusing the car parks.
Stephen Palmer, councillor for Alford and Sutton, said: "I'm very sorry to say that it's their own selfishness which has caused this problem.
"For instance, last Bank Holiday, in the May, people couldn't get on to the site because there were so many of these vans on the site with people living in them. So it stopped people using it as a car terrace."
The protesters parked four motorhomes on Huttoft Car Terrace before the barrier was locked, and they were joined by other supporters in cars.
They left the site on Tuesday, after the barrier was unlocked to let them out.
Height barriers had previously been installed at the council car parks at Marsh Yard, Anderby Creek, Chapel Six Marshes and Wolla Bank.
'Human right'
Motorhome owner Bob Farmer said he had been enjoying the views at Huttoft Car Terrace for about 40 years, but the barrier means he can no longer do so.
"I didn't purchase a motorhome to go on campsites," he said.
"The right to roam, I feel, is my personal liberty as a human right."
He said the presence of motorhomes in the car park deterred people from committing crimes.
"We don't get the perverts using the toilets or boy-racers running up and down being intimidating," he said.
Other protesters said they just wanted to access the car parks during the day.
Paul Marriott, from Spalding, said: "We feel a little bit discriminated against because we can't now go and look at the wonderful views."
He agreed that the car parks should not be used as free campsites.
"What we are asking for is to be able to go up there in the daytime," he said.
"Obviously we have camped up there, but we have never been challenged and told that we couldn't."
